GigaWatt PC-4 Evo+ Power Conditioner

Written by: Jeff Fritz
Created: 15 October 2019

GigaWatt is not widely known in North America, but Mark Sossa, of distributor Well Pleased Audio Vida, hopes that will soon change. Founded in Poland in 2007, GigaWatt’s history stretches back further, to 1998, and the founding of Power Audio Laboratories by Adam Schubert, a young electronics engineer with a passion for high-quality audio. P.A. Labs remained obscure until the Audio Video Show of 2002, where Schubert and his products gained wider recognition from attending audiophiles and the press. After that, P.A. Labs created GigaWatt as a separate brand, with Schubert at the helm.

Luxman D-380 CD Player

Written by: Garrett Hongo
Created: 01 October 2019

In Eugene, Oregon, where I live, there used to be a mom-and-pop electronics store downtown, near the bus station and public library. It was the kind of place you went to pick up a pair of old Advent or Infinity speakers, a new stylus for your vintage record changer, a used CD or DVD player, or basic lamp cord to wire up your living-room stereo -- everything you needed for a cheap but good system was there. It was called Thompson Electronics, and I guess it had been there since the 1960s, occupying a storefront kitty-corner to the St. Vincent de Paul, where I’d sometimes scrounge for used LPs. Making only one downtown stop, I could get mounting screws for a phono cartridge and a new old record.

SGR Audio Model III Symphony Equipment Rack

Written by: Jeff Fritz
Created: 15 September 2019

I’m not an audiophile who haphazardly throws money at components. Nor do I open my wallet because of some preconceived notion of what proportion of an audio-system budget “should” be allocated to a given product category. This thinking has led me to assemble and own, over the years, audio systems that some might say are unbalanced, at least in terms of cost. For instance, I’ve almost invariably chosen to spend large portions of my budget on loudspeakers, because I’ve found that a change in speakers usually provides me with the biggest improvement in sound quality. I typically spend less than a tenth as much on a digital source component, because in the last decade or so great digital sound has become so affordable.

TAD Evolution One TX Loudspeakers

Written by: Jeff Fritz
Created: 01 September 2019

In November 2017 I reviewed the Technical Audio Devices Micro Evolution One loudspeaker, aka the TAD ME-1. It now costs $14,995/pair USD, including TAD’s ST3 stands, and at the time we gave it a Reviewers’ Choice award. The ME-1 is pretty small at 16.2”H x 9.9”W x 15.8”D, but its size had little correlation with what I heard. Of the many things I noticed about the ME-1’s sound, what most surprised me was what I wrote about in the penultimate paragraph of my review: “It filled my Music Vault with full, rich, detailed sound that never fatigued me and never bored me.”

McIntosh Laboratory MT10 Turntable

Written by: Jeff Sirody
Created: 15 August 2019

McIntosh Laboratory was founded in 1949, when vinyl was a growing source for music reproduction. But it wasn’t until nearly 60 years later that the venerable company, based in Binghamton, New York, introduced its first turntable model. The debut of the MT10 turntable ($11,500 USD) was polarizing: Those who first saw it loved it or hated it. I remember some of the comments: “A turntable with a meter? Why?!” or “I don’t care how it sounds, it just looks too odd.” But most of the people who panned it had yet to hear it.

Magico A3 Loudspeakers

Written by: Hans Wetzel
Created: 01 August 2019

Reviewers' ChoiceIn June 2016, when I reviewed Magico’s S1 Mk.II loudspeaker ($16,500/pair; all prices USD), I loved it. “The finest two-way speaker I’ve heard,” I declared. In late 2017, when Magico announced their new entry-level model, the A3, I was cautiously optimistic. The A3 struck me as a vitally important product for Magico, which had built its reputation on speakers whose performance ceilings were exceeded only by their sky-high prices. As with everything else in life, if you want the state of the art, you have to cough up the dough. The A3’s original price of $9800/pair put it in direct competition with models from many hi-fi heavyweights. And there was something else: Would the A3 look and feel like a Magico speaker? Most important, would it sound like a Magico?

Merrill Audio Element 118 Mono Amplifiers

Written by: Aron Garrecht
Created: 15 July 2019

Merrill Audio Advanced Technology Labs, LLC, was founded in 2010 by Merrill Wettasinghe, who not only earned a BS in electrical engineering and an MBA, and enjoyed a career in R&D and marketing with Hewlett-Packard, but has long had a passion for purity of sound. In 2011, Wettasinghe released the first Merrill Audio amplifier, the Veritas monoblock ($12,000 USD per pair, discontinued). The Veritas was considered a breakthrough product not only for its sound quality, but also for being one of the first amplifiers to be based on Hypex’s Ncore NC1200 class-D power module. At the time, it was also one of the few amps to use point-to-point litz wiring of ultrapure copper, rhodium-plated binding posts of solid copper, and top-quality XLR connectors -- all made by Cardas.

Valve Amplification Company Master Preamplifier

Written by: Garrett Hongo
Created: 01 July 2019

When I was a teenager growing up in South Los Angeles in the 1960s, the most vaunted among us were the guys who tinkered with their cars and souped them up with fuel injection, overhead cams, dual carburetors, heavy-duty MacPherson strut suspensions, and 8-track super stereos with speakers arrayed in the dash, the doors, and the rear deck under a tinted back window. This was the SoCal car culture celebrated by the Beach Boys in “Little Deuce Coupe,” “Fun, Fun, Fun,” and “Don’t Worry Baby” -- male-teen sexual prowess sublimated and distilled into small fleets of superb, gleaming machines and gallant jalopies. A guy I knew in my neighborhood was always under the hood of his ’50s Dodge coupe, working some sort of magic I had no clue about. His father and uncles were partners in a gas station and garage, and my friend had been a grease monkey since childhood, at first just pumping gas and changing tires and spark plugs, but quickly advancing until he could swap out stock parts for custom, fine-tune an engine’s timing, raise a car’s suspension, and supercharge everything in his inline six engine until it could accelerate faster than a stock V8. He was a marvel among us and his wheels were so cool, he got all the girls we could only dream of dating.

Constellation Audio Revelation Andromeda Phono Stage

Written by: Jason Thorpe
Created: 15 June 2019

Reviewers' ChoiceAs soon as Doug Schneider approached me about my reviewing Constellation Audio’s Revelation Andromeda phono stage, I hopped on their website and snooped around.

You gotta love these guys. They offer two -- count 'em -- phono stages, and not just because LPs are now big on Instagram. No, Constellation Audio is spreading analog love around, like soft butter on toast.

Audio Research Reference 6 Preamplifier

Written by: Aron Garrecht
Created: 01 June 2019

Reviewers' ChoiceIn late 1972, Audio Research Corporation released what would become one of ARC’s bestselling preamplifiers of all time: the SP-3. While available, the SP-3 earned praise for its low noise levels, wide soundstages, and awe-inspiring transparency. More than one audio publication described its overall sound character as “a straight wire with gain.” ARC sold thousands of SP-3s at $595 USD before discontinuing the model in 1976, but what I find interesting is how much of the SP-3 remains evident in more recent ARC models. By today’s standards, the SP-3’s faceplate of brushed bronze over satin black, rotary analog controls, and big pushbuttons look dated, but the three-box segregation of the faceplate and orientation of controls aren’t all that different from those of ARC’s SP-20 preamplifier ($9000, recently discontinued). Then there was the SP-3’s tube complement: six 12AX7s in the analog stage with two 12AX7s in the tone control circuit. This arrangement in the analog stage, albeit with different tubes, can be found under the hood of the subject of this review: ARC’s Reference 6 preamplifier.
