It was hard to find focus in Victor Kung's room. Between the nearly invisible AER BD3B/650mm full-range open-baffle speakers ($9800/pair) and the various amps on static display—Sun Valley SV-1616D 300B integrated amp ($2450), or the Elekit TU-8900 ($3050) or Elekit TU-8850 ($1850) power amps—my palms felt sweaty, my head, dizzy. Is this SET-amp lover’s heaven?
Victor’s active setup included a VPI 40th Anniversary HW-40 Direct turntable ($22,000) with the fantastic Hana Umami Blue MC cartridge ($2000) allied to a Sun Valley EQ161D phono stage ($1585), Pre161D preamplifier ($1550),…
There's something inherently suspicious about most all-in-one solutions. They promise convenience but whisper compromise. It's a bit like those Swiss Army knives with 14 attachments: The corkscrew is barely adequate, and the other tools are terrible at everything. And it isn't just quality. The audiophile brain, trained over decades of mix-and-match rituals, recoils instinctively. Where's the fun in a speaker that arrives with amplification baked in? Where's the journey of pairing, the thrill of synergy discovered at 2am after your sixth cable swap?
And yet. Sometimes the all-in-one…
I own a lot of records. Way too many if we're being honest. It's hard for me to come up with an accurate count, and I'm not even remotely organized enough to have a formal inventory, but if I had to make a guesstimate based on linear feet I figure I must have around 10,000. About 10 years ago, I started to recognize that I owned far more records than I could ever hope to listen to, even once, in my remaining time on the planet, and since that realization my record purchasing rate has slowed to a trickle.
These days, my worst weakness kicks in when I'm visiting my friend of over 45 years,…
Sidebar 3: Measurements
As Jim Austin primarily auditioned the CH Precision L1 using its direct-coupled balanced inputs and outputs with the gain adjust set to "0dB," the input impedance set to High, and with the preamplifier powered by the auxiliary X1 supply, I performed a complete set of measurements in that condition. (The manual says not to stack the L1 and X1; the supplied umbilical cable was long enough for me to place the X1 on the floor, well away from the L1.) I then repeated some of the tests using the unbalanced inputs and outputs, then performed the balanced input's…
Sidebar 1: Pascal's Wager: Betting on Class-D Pro Audio
Twenty years ago, the Danish amplifier specialists at Pascal Audio hand-built their first prototypes in a small lakeside cabin near Copenhagen. From the start, the firm specialized in electronics for self-powered loudspeakers and amplifier systems. It now partners with audio brands in more than 70 countries.
If you're not familiar with Pascal amplification, you're not alone; it's probably the least well-known of the class-D amplification companies. It positioned itself as a behind-the-scenes supplier to PA loudspeaker…
You’re going to need to indulge me a bit, because, due to some communication difficulties, I’m not totally confident of some prices and components in this room. If I understood correctly, the handmade-in-Japan, 1-bit Sparkler Audio S503 CD Player/Transport costs $1650, and the build-it-yourself EleKit TU-8600R integrated amplifier, also from Japan, goes for $1785. The loudspeaker system appears to be custom, from AER, including that company's BD2 driver (3000 each, according to the AER website) in an acrylic stand that looks like AER's Custom (€5500/pair) but with the addition of the larger…

On the front page of its owner's manual, Greek amplifier manufacturer Lab12 describes the Melto2 ($4995, footnote 1) as a "Remote Controlled, Fully Adjustable Phono Preamplifier." I'd describe it as a clear-speaking, fun-to-use, cartridge- and record-collector's dream. Plus: It's got tubes.
Apart from delivering an uncanny level of silence and transparency, the #1 special thing Lab12's tube phono stage can do is allow users to fine-tune resistance, capacitance, and gain to create maximally effective loads for both moving coil and moving magnet cartridges. These diverse capabilities…
