To Jason Thorpe,

Very nice review of the Vivid Kaya 45 loudspeakers. As a Torontonian now living in California, I enjoyed the Canadian references throughout the review.

I wonder if you can give me a little bit of advice. I am narrowing down on three speakers for my smallish office, 12’L x 11’W x 9’H: Paradigm Persona 3F, Vivid Kaya 45, Yamaha NS-5000.

I have heard the Paradigm Persona 5F and feel that the smaller Persona 3F with an Anthem STR preamp with ARC3 DSP would work. The same preamp [paired] with Vivid Kaya 45 [speakers] -- I am not sure because of the side-firing woofers. I have not heard the Yamaha yet since it is not available yet in the USA, though I understand it may be in the summer. I may come up to Toronto to have a listen this summer whatever the case.

I have heard the Vivid Kaya 90s, and liked them a lot, and the Vivid Kaya 45s are supposed to play in smaller rooms and can be placed closer to the back wall, due to the canceling of some of the rear sound waves.

My office is treated with acoustic treatments and it sounds real good now. Can you give me some feedback as to whether the side-firing woofers are a bad choice for such a small room?

If you have heard the other two speakers on my list, do you have a favorite amongst the three?

Regards,

Dimensions of 11’ x 12’ x 9' make for a fairly small room for the Kaya 45s -- it's also quite square. But if you do have it well treated, you might be fine. Also, if you’re using Anthem Room Correction (ARC), you may well be able to ameliorate any nasty standing waves. I also don’t believe the side-firing woofers will cause any problems, since low-frequency sound waves are so long, though the only way to be sure is to listen to them, unfortunately. I also suggest you contact Vivid themselves, as they can likely give you some further insight.

Regarding the Personas -- at the Toronto Audio Fest this past year, I had a chance to hear the Persona 9H loudspeakers driven by the Anthem STR integrated amp, and they sounded fantastic, so I think you have a hard choice ahead of you.

I also had the chance to hear the Yamaha NS-5000 speakers, but they’re large boxes, and might well overpower your room. But again, maybe ARC will be able to help.

In the end, though, if it were my money, I think I’d choose the Vivids. . . . Jason Thorpe

To Hans Wetzel,

I’ve read your article about the Gryphon Diablo 300 and you wrote that you used Sonus Faber’s Venere S to test, among other speakers. I want to ask if [the] Diablo 300 and Venere S speakers were a good match? I got the Venere S speakers and am going to change to the Diablo 300 or the T+A 3100 HV. Home demo is not available in my country, so I’m [wondering if the] Diablo 300 would be a good match for my Venere S speakers. Thank you.

Hieu Nguyen

I think Gryphon’s Diablo 300 is a fantastic amp, and with its massive power reserves, would work well with just about any loudspeakers, including a pair of Venere Ses. As you can tell from my reviews of both the Diablo 300 and the Venere S, products that I used in tandem with one another for each review, I certainly liked what I heard. I think you will, too.

I will say, however, that the Diablo 300 is probably overkill for this application, as is the T+A 3100 HV. Something like Gryphon’s Diablo 120 or T+A’s PA 2000 R, the latter of which I reviewed back in 2016, should have no problem driving the Venere S speakers to their full potential. With a 90dB efficiency rating and a nominal 4-ohm impedance, the S should be a breeze for either amp to drive, since each offers at least 200Wpc on tap into a 4-ohm load and plenty of current. Personally, I’d opt for one of these amps and pocket the difference for upgrading my DAC, turntable, or speakers going forward. Should you decide to plump for the Diablo 300, however, you can be secure in the knowledge that you’re buying one of the very best integrated amplifiers out there. Good luck! . . . Hans Wetzel

To Howard Kneller,

Thank you for your very insightful review of the Furutech cables and connectors.

I am in the process of changing my power cables and I’m strongly considering the FP-TCS31 as my bulk wire of choice. I currently already own the FI-28(g)/FI-38(g) AC and IEC plugs that I intend to use with this cable. I require ten cables in my system, so the choice is a big one and I cannot change my connectors to the NCF version at this point.

You briefly mention these FI-28(g)/FI-38(g) connectors in your review but I was hoping to get some more clarity. How would you rate the power cords’ performance with these connectors on them? I basically like a very open, transparent, and fast sound and wanted to see whether you think that combination would fit the bill.

If you have any other recommendations regarding bulk cable from Furutech or any other manufacturer I would be glad to have them.

Thank you.

Best Regards,
Rahul

Thank you for your e-mail and kind words about my Furutech review. The company’s FP-TCS31 bulk power cable, which uses the Alpha PC Triple C conductors, is an excellent choice considering your sonic preferences. With the FI-28(g)’s and FI-38(g)’s gold-plated connectors, you may find another Furutech choice for bulk cable, the FP-S032N, for example, to be a bit too warm sounding and bass heavy.

I am not looking to have you spend more money, but do not forget the absolutely crucial role played by the AC wall outlet. I suggest your power products be from only one manufacturer, whichever one you choose. Sticking with Furutech, you may like the GTX-D NCF outlet, whose rhodium-plated conductors may also give you just what you are looking for.

Note that too much of a good thing can be just that. Sometimes, no one power cord or wall outlet works best in every area of a system. You may have to experiment with several products to obtain the balance that suits your sonic preferences. I would therefore take one step at a time.

I hope this helps. Please let me know how it works out. . . . Howard Kneller

To Jeff Fritz,

I am writing about your quest for new speakers, and your final pick: the Vimberg Tonda. I heard the Vimberg Mino at RMAF this year and spent quite a bit of time in that room discussing the new brand with a few of my friends and with Doug White of [Vimberg US dealer] The Voice That Is.

I currently own Wilson Alexia Series 1s, which are speakers I have aspired to own for years. I never felt like I was missing anything with them, but the Vimbergs really impressed me and my friends. They are some of the most musical speakers I’ve heard. Horns were bright and powerful but not edgy or shouty. Piano sounded like the real thing. Bass was tight and deep. Soundstage was huge. All this in a crappy hotel room!

I’ve heard people denigrate Wilson as “colored” and not neutral. I’ve usually dismissed these criticisms, but I admit the Vimberg sound seems truly neutral. I’ve heard similar sound from other speakers that utilize Accuton drivers. There must be something to these drivers . . . they never fail to impress me.

I am curious how you would characterize the Tonda vs. the Alexia from what you currently know. I realize you didn’t spend a lot of time with the Tonda, but you’ve probably heard the Alexia a million times and are likely familiar with its capabilities. I’m going to follow your articles and I am looking forward to your thoughts once you spend some time with them. What I’m really looking for is an educated opinion on whether they constitute an “upgrade” from such a well-regarded speaker as the Alexia. Maybe you could compare against other well-known speakers that you have a lot of experience with? Do you have any thoughts regarding speakers employing Accuton drivers?

Thanks in advance and I look forward to following your journey.

Marc

First, let me address your question about Accuton drivers. I do think they are very good drivers, and that is certainly borne out through the measurements that Accuton publishes. However, a raw driver that is well designed in no way automatically translates into a great, or even competent, final loudspeaker product. In fact, I can say that I’ve heard a number of Accuton-based loudspeakers from brands other than Vimberg and Tidal that have not impressed me, just as I’ve heard a number of excellent drivers from other OEMs in really poor commercial speakers. The bottom line is that all Accuton-based speakers are not created equal -- not even close.

Do I think the Vimberg Tonda would be a proper upgrade path for you? I do, actually. I’ve heard the Alexia a number of times at shows and it has some strengths, dynamics being one. Neutrality is not, however, a strength that I would attribute to the Alexia. You can examine the measurements that John Atkinson posted on Stereophile’s website and draw your own conclusions, which may or may not support what you hear in your own room with your electronics. From what I’ve heard, as well as from what I’ve seen from measurements of the Vimbergs (and Jorn Janczak-designed speakers in general), these are exceptionally neutral loudspeakers. My educated guess would be that you would experience a more neutral sound than you have now, but also one that is higher in resolution.

I am not reviewing the Vimberg Tonda because, at this point, I’m not a neutral observer. I bought a set of Vimbergs, as you know, so clearly I’m biased. That bias comes honestly though: I think the Vimberg speakers are tremendous performers and are better than many well-regarded, five-figure speakers on the market today, which is why I laid down my money. . . . Jeff Fritz

To Jason Thorpe,

Enjoyed your review of the VPI Prime Signature package. It became my destination table this past spring and have greatly enjoyed it since. I opted for the Rosewood finish, which takes it to a whole ’nother aesthetic dimension and obliterates any concerns regarding appearance -- it’s stunning.

The one thing you missed on is the cueing mechanism of the tonearm -- it is damped. It's just another one of those analog things where you gotta do it just so to make it work. It requires that you lower the lever .5” or so (somewhat quickly and purposefully), then release it and the damping kicks in. It takes a few tries to get the hang of it, but once you get it, it’s second nature. Gives you a few seconds to get to your chair before it eases into the lead-in groove.

If you should opt to make the Prime Signature part of your daughter’s inheritance, there is one more piece you’ll need to consider. The FatBoy Gimbal tonearm is a monster on that turntable! Gave myself one for Christmas and while I’m still getting acquainted, it’s obvious that it’s a significant improvement over the 3DR and ensures that this will be my final analog front-end -- unless, of course, my ship comes in with the winning lottery ticket!

Best regards and wishes for a happy holiday season,

To Jason Thorpe,

Just a quick note to thank you for your excellent review of this extraordinary album. I was about to order the Classic Records copy. My wife and I are HUGE Junkies fans and saw them again three weeks ago in London for another amazing night of music. Margo [Timmins’s] voice still sounds amazing and the whole band were just awesome. Also got to meet Margo, Pete, and Jeff. Will order the Acoustic Sounds album now.

Thanks for your great review.

Cheers,

To Hans Wetzel,

I came across your reviews of Dynamique Audio cables while looking up Nordost Heimdall cables, which as search engine results so often go, you didn’t review. My curiosity about the Dynamiques, in particular, their interconnects as a possible indicator for my purposes (S/PDIF), is about the degree of warmth they bring. Or do they fall in that tonal category called neutral?

I realize some people don’t make the distinction between neutral and warm, considering the natural warmth of most live acoustical instruments to be neutral. I wish it were so easy. It’s struck me since picking up this hobby again several years ago that high-end listeners, and the equipment developers that are designing for them, fall into two broad categories: those of us who start with or gravitate to tonal/timbral accuracy in choosing equipment, which to me means a modest degree of warmth; and those who are more focused on “sonic effects,” i.e., detail, transparency, staging, PRAT [pace, rhythm, and timing], and such. The latter tend to characterize the sound as “neutral,” tonally. To me, it’s some degree of cool. I came to realize that these different preferences stem from a variety of factors, such as hearing ability, musical background, and perhaps what one has come to believe is considered good sound. As for myself, while of course I like those sonic effects, “neutral” soon leaves me wanting to throw my equipment out the window.

Gene Goldenfeld

Well, you’re correct that I didn’t review Nordost’s Heimdall cables, but I did review a “loom” of their Frey 2 line. As for your question about warmth vs. neutrality, I’m not sure I can provide a straightforward answer, as it appears you and I define these terms differently. But I certainly appreciate your perspective and the kind of sound that you’re looking for. Broadly speaking, I don’t think Dynamique’s cables will impart any real sonic signature on the sound of your system; however, compared to Nortdost’s cables, which I certainly think meet your definition of “neutral,” Dynamique’s cables may well sound somewhat warm. But if you’re looking for a cable brand whose overall sonic signature is quite warm and very sweet through the midrange, you might have to look elsewhere. For what it's worth, though, if you’re using a competently designed, modern DAC, your S/PDIF cable choice shouldn’t affect the sound quality of your system. . . . Hans Wetzel

To Jeff Fritz,

I have read many of your excellent audio reviews on SoundStage! Ultra, mainly DACs and those rather special Esoteric VRDS-NEO transports, which I also hold in high regard.

My audio experience and product research is firmly based on the studio side of the industry, but I am also an audiophile like you at heart. I have been looking at a couple of DACs recently, which you have reviewed and possibly even owned: the Weiss DAC202 and Hegel HD30 -- these two DACs are about the same price now used.

Now I know the Hegel HD30 is a newer DAC, and has more features compared to the Weiss DAC202, but if you were to select one or the other, taking into account the quality of both volume controls and purely on the overall sound quality (i.e., which converter mirrors the best analogue sound and reveals the room acoustics/instrument echo trails the clearest), which would you choose?

The only other converter I will be trying to get my hands on will be the Bakoon DAC-21 battery-powered DAC. I have a soft spot for certain high-quality battery DACs, having owned a LessLoss DAC 2004, which was completely handmade, hand-soldered, and hand-assembled -- a great DAC with those now out-of-production Burr-Brown PCM1704K chips.

I look forward to hearing from you.

Paul

I have not used the Weiss DAC202 in a great while, so my memory of it is sketchy at best. I know that when I reviewed it years ago I was super impressed, but that was a long time ago, so I can’t be sure of where it stands now. On the other hand, I know the Hegel HD30 really well, having used it for months now. So my initial reaction would be to tell you to go with the Hegel. It is a really fine DAC with clear, precise sound quality. The one hesitation I have with that recommendation is knowing that Hegel recently released the new H590 integrated amplifier-DAC, with reportedly a better-sounding DAC inside than the standalone HD30. Could a new Hegel flagship DAC be too far away? Probably not.

I have no experience with the Bakoon DAC that you mention. I will give you one bit of advice, though: although I am a huge proponent of buying some products used -- amplifiers and preamps come to mind -- I don’t think buying a used DAC is necessarily the best way to go. DAC chips have gotten way better over the years. A newer DAC might outperform an older one that retailed for twice the price. In other words, DACs are always getting cheaper and better. The bottom line from my perspective is to buy as current as you can when it comes to digital. Good luck in your search. . . . Jeff Fritz

To Garrett Hongo,

I have been in this hobby for 65 years and have grown up with classical music, and your wonderful review of the Esoteric K-05X SACD/CD player painted a wonderful word picture of what you heard in your listening to classical music. Unfortunately, it is a little more expensive than I can spend [unless the wife can loosen the purse strings]. Thus, the reason for my e-mail: Would you, if you have heard the K-07X Esoteric SACD/CD player, be able to give me your impressions of its presentation of large orchestral classical music, especially its string sound?

I have read extensively on its technical merits, the transport, and the power supply. Can you make some general descriptions of how these technical differences translate into transparency, bass definition, frequency extension, lack of steeliness, presentation of soundstage, [and whether it has] sweetness like tubes?

I would appreciate so much your insights. It was a great review.

Highest regards,
Tony

Thanks for your question and your appreciation of my review of the Esoteric K-05X player. I’ve only heard the older K-07 player and that was at a show long ago now, so I can’t give you a useful view of the new K-07X player, though our own Tom Mathew did review it in January 2016, so I do recommend reading what he wrote. But, in general, I find Esoteric players quite superior to others in their price range, a lot because of the attention to the rigidity and reinforcement of the proprietary transport assemblies. However, that said, the K-07X player uses a different transport mechanism than the K-05X.

I think the Esoteric K-05X transport has a lot to do with bass response, extension, and refinement (what you may hear as transparency). As far as sweetness and lack of steeliness go, I attribute that to the DAC. I had a Cary 303/300 tube-output player I’d kept for years (because of finesse and sweetness of string sound) before the K-05X. I found the Esoteric was comparable in sweetness, but even better with resolution. A better DAC does wonders for string sound, depth/layering, and resolution.

Mind you, I’m not endorsing the K-07X as I’ve not heard it. My recommendation is to audition a K-07X and judge for yourself with attention for what concerns you and what I’ve pointed out about the K-05X. . . . Garrett Hongo

To Jeff Fritz,

That [“Jeff’s New Room”] bump-out might not be a bad thing. I feel like sometimes symmetry creates its own problems with lower-frequency hotspots.

Will you have the bathroom/closest doors open or closed? I think it’d be interesting to try both. Your new listening room may have two tunable bass ports.

Congrats on the new house. Looking forward to reading about the set-up process.

Yuan Lu

I am sitting here wondering how I could have missed such an interesting proposition! I can easily imagine that you are right, and that the closet and bathroom, being essentially enclosed in the overall structural envelope of my room, would have a significant impact on the sound depending on whether the doors to those spaces are opened or closed. I will check that out, and also measure the differences acoustically (if there are in fact differences to measure). I am slowly learning about the new room’s sonic signature, and this adds one more variable I will have to take into consideration. Thanks for pointing it out. . . . Jeff Fritz
