Mind you, raising the volume significantly isn’t a quick process if you use the remote control as there is no acceleration to the volume knob’s fairly sedate rotational pace. Yet give the chunky knob a few seconds to reach 12 o’clock or beyond and you are rewarded with wildly swinging VU meters and sound that packs serious enough power for ASBO level SPLs with all but the most insensitive speakers.
With even modestly efficient speakers the Vouvray is more than happy to indulge party-level sound pressures and it didn’t hold back on the dancefloor when I spun up the anthemic ‘We Come 1’ from Faithless’s seminal Outrospective [Cheeky 74321 86555244/16]. If an amp can make me leap off the chair to thrust a pointed finger in the air and belt out the chorus like I am at Glastonbury, it’s a good ‘un in my opinion. Job done, Supravox
Wilson Audio • Chronosonic XVX Loudspeakers and Subsonic Subwoofers $329,000 Review

About the fine-tuning. As with other Wilson speakers, a step in the setup of the XVXes is measurement of the listening position, both in distance from the speakers as well as the floor. This is done to determine the correct settings for the various modules, in order to achieve exact time alignment at the listening position. But there’s also an important procedure that tailors the speakers to the amplifier with which they will be used. While previous Wilson models other than the WAMM used predetermined steps for time alignment of the drivers, the Gantry and Micrometer of the XVX allow infinite small incremental adjustments to correct not just for listening position but also the unique time smear of the partnering amplifier. Wilson Audio determines this through measurement of the amplifier, and those data are provided to the person setting up the speakers. Daryl Wilson admits that there are some similarities among the amplifiers he has measured, especially ones with similar topologies, but, as he put it, “Every manufacturer has its secret sauce.”
Grimm Audio MU1 Music Library/Server Review

It may seem counter-intuitive that a downsampled version should sound better, but it’s testament to the quality and undoubted innovation of the code and clock that ultimately feeds the MU1’s balanced AES3 digital output.
Hearing it makes clear just what the engineers were trying to achieve. That the design has managed so much more, not only justifies the existence of the MU1 as a digital source, but also proves that a DAC is only as ‘good’ as its partnering digital front-end.
Pass Laboratories XP-32 line preamplifier Review

I had two high-performance preamplifiers on hand with which to compare the Pass XP-32: the MBL N11 ($14,600) and the Benchmark LA4 ($2599) that had so impressed Kal Rubinson when he reviewed it in January 2020.
First up was the MBL, with sound pressure levels matched within 0.5dB at the listening position. (The N11 was set to its unity gain condition, which limits the maximum gain and which reviewer Jason Victor Serinus had preferred.) With the MBL N31 DAC in front of the preamplifier and the Parasound monoblocks behind it, the back-to-front soundstage on my Mozart Piano Quartet recording was as apparent as it had been on the XP-32, with as much image depth. The tonal balance, however, was a tad warmer and the presentation of acoustic objects within the soundstage was a little more—and how I hate using this word—palpable. For example, toward the end of the Joni Mitchell track, a high tenor voice appears in the center of the stage, floating slightly behind and slightly above Joni The MBL pushed this voice a little farther back than it had been with the Pass Labs, as well as a touch higher. A close-run thing, but like I said, more palpable.
KEF KC62 Subwoofer Review

The fact that a literally breadbox-size subwoofer can produce actual 25 Hz-and-lower content at any musically useful level is newsworthy. And so is the KC62 as a whole: if you insist on breaking Hoffman’s Iron Law, or at least bending it to its limits, KEF’s inaugural Uni-Core design does so as dramatically, and as classily, as any sub I’ve seen. Within the “iron” caveats of a small room and/or relatively modest level demands, it will match the performance of a well-engineered 12-inch sub in every important parameter except peak dynamics and level. There may be other mini subs on the market, but none I know of go quite as low in quite as small and elegant a package as what KEF has managed with the KC62.
BENCHMARK MEDIA HPA4 PREAMPLIFIER-AHB2 POWER AMPLIFIER-DAC3 B DAC REVIEW
March 3, 2021 Comments Off on BENCHMARK MEDIA HPA4 PREAMPLIFIER-AHB2 POWER AMPLIFIER-DAC3 B DAC REVIEW
This is a time-domain plot of a -90 dBFS signal applied to the Oppo BDP-105D on the left channel. It is included here as a reference. The self-noise of the QA401 spectrum analyzer in time-domain mode is shown on the right channel which is grounded. The QA401 can be seen to have a suitably low noise level for something that isn’t an Audio Precision analyzer. Again the trick is here is in the range extension the Benchmark is providing me. The QA401 has a signal limit of 2VRMS but the Benchmark DAC3B is at 12.3VRMS. All the signals that will be presented in the following figures are far smaller than 2VRMS so the QA401 is safe with the Benchmark but the fact the output level is so much higher than 2VRMS range extends the QA401 by 15.8dB. With this trick the QA401 has the SNR of an AP but only because the Benchmark has such a high, ultra-low noise, output.
