"After one year of setup," Bednarski told me, "we debuted our line at the January '95 CES. You know, Victor and I came out of Hewlett-Packard, a real pay-as-you-go company. And that's how it is here at BAT—no outside financing, no debt, and, I'm happy to say, a loyal and growing customer base." BAT is one of the few high-end companies that can claim a genuine…

Designer Victor Khomenko goes through a lot when designing BAT products. For one thing, he "listens" to the circuit boards and components.
Victor: "We have to listen to the noise they make to know how they're behaving. Listening through a normal home audio system, you'd hear no noise and think everything's fine. But we have to go deeper than that. Like a doctor with a stethoscope, we amplify the completed boards to check their heartbeat and breathing. The nature of the noise tells us a lot. It should sound uniform,…
Most of the time the VK-D5 was wired up to the VK-5i preamp to take advantage of differential operation. Unsurprisingly, the two pieces mated beautifully. I wired up the front-end, the VTL Wotan amps, and the JMlab Utopia speakers with either Synergistic Research Designer's Reference or TARA Labs The One, with its multiple Isolated Shield Matrix Floating Ground Stations. The VK-D5 also served the Forsell Statement amplifier on the Radian HC speakers. (This combo must be heard to be believed. The Forsell's inherent bloom perfectly complements the HC's…
The BAT offered superb error correction, playing without skipping through the Pierre Verany test CD's track 33, which has a deliberate 2mm gap in the data. The BAT's output was noninverting from both single-ended and balanced jacks with the blue Invert LED off. (Pin 2 on the XLRs is wired to be "hot.") At 2.175V, the output level from the single-ended RCAs was 0.7dB higher than the CD-standard 2V. From the balanced jacks, the output level doubled to 4.36V. The single-ended output impedance was a moderate 882-908 ohms at middle and high frequencies, but rose to a…

The analog output levels of the $4500 Balanced Audio Technology VK-D5 and the $4950 Wadia 850 matched to within 2mV, so no additional level matching was necessary. All comparisons were done using the Levinson No.380S preamplifier. As well as side-by-side comparisons involving disc swapping from one player to the other, I used the BAT to drive one of the Wadia's coaxial data inputs via a 0.5m length of Mod Squad Wonderlink I fitted with BNCs. Interconnects were balanced: initially, the softer-balanced CZ-Gel for…
There's plenty of nail-biting over digital these days, and with good reason: SACD, DVD-Audio, "Red Book" CD...it's enough to get an audiophile totally confused. Balanced Audio Technology's solution to the dilemma is the VK-D5SE, a $6000 one-box player that simply gives you, according to BATman Victor Khomenko, the best playback possible of that big collection of 16-bit/44.1kHz CDs bending your shelves.
The VK-D5SE is an updated version of BAT's VK-D5, that I reviewed in the May 1998 Stereophile (footnote 1).…
