“The PA-One+ utilizes an two-channel ‘audiophile grade’ HyperStream ESS Sabre 9018K2M ‘Reference’ DAC chip capable of both asynchronous and synchronous 32-bit/384kHz PCM and DSD256 decoding. For this review I ran a Roon Nucleus+ into the PA-One+ with 16-bit/44.1kHz (FLAC rips) 24-bit/192kHz, DSD64/128 local-drive downloads and TIDAL and Qobuz streaming files. I did not tube roll the Quad as even though I have acquired (and continue to acquire) ever more tubes, they tend to input/line/phono applications, and I had no varietals of 6SL7/6SN7). I did not use it as a pre-amp either, rather, I focused on it’s headphone amp/DAC abilities. I used a variety of headphones, of varying impedances and sensitivity from the Audeze LCD-2 Classic, Mr. Speakers Aeon Closed, HIFIMAN HE1000se to Quad’s own Planar-Magnetic ERA-1, which had real synergy with the PA-One+ and that I settled on for all my critical-listening and review sessions.”

SONUS FABER MINIMA AMATOR II BOOKSHELF SPEAKER $4,000 REVIEW

“First, I found that I preferred the overall sound with the speakers closer to the rear walls than usual. I settled on about 30 inches between my front wall and the speakers’ rear baffles. I thought that this would make the bass a bit too boomy, but that was not the case. I also preferred the sound with the speakers a bit closer to” each other than usual. My final placement put the speakers six feet apart and 9.5 feet from my listening position. I adjusted the toe until the speakers converged at a point about two feet behind my head. This gave me the best overall tonal balance as well as optimizing imaging and soundstage depth. I didn’t feel the need to add any rake to the setup as the tweeters were sitting at ear level for me and sounded nicely balanced as is

AudioQuest DragonFly Red Review

“The first thing I did once I unpacked the Red from its simple, but adequate box was trip a bit at just how small everything had to be inside the sleek casework. I tripped less than I did when first assessing the Apple Lightning dongle years ago and how small the amp/DAC combo is in it, but, nonetheless, knowing what AudioQuest was able to pack inside the ‘fly series cannot help but leave you impressed at Gordon Rankin’s circuit design (of Wavelength Audio – podcast interview with him HERE) and all the custom coding that went into to making it sound as ballsy and colorful as it does.”

Focal Chora 826 Three-Way Floorstanding Loudspeaker Review

“Each Chora 826 sports one pair of binding posts, so bi-wiring isn’t accommodated. Overall, I really love the quality of the binding posts, as they’re easy to loosen and tighten and look quite lovely. If I have one concern, it’s that tightly fitted black and red caps will need to be removed if you intend to use banana plugs (as I always do), and these caps do put up a good bit of a fight. I had to end up resorting to needle-nosed pliers to extract them, and it felt a bit like pulling a tooth. By the time I had them out, the caps were more than a bit mangled.
From there, though, setup is a breeze. Due to the front-ported design of the speaker, you don’t have to be quite as concerned with distance from rear boundaries. In my relatively small two-channel listening room, this is a blessing. Being able to position a pair of speakers six inches from the wall rather than eighteen definitely leaves me with more breathing room and affords a wider soundstage, since there’s more distance between me and the speakers.”

Stromtank S2500 Battery Power Supply Review
March 5, 2020 Comments Off on Stromtank S2500 Battery Power Supply Review
“There are a few words when describing the sonic results of using the Stromtank to power my system: astounding, awe-inspiring, awesome, amazing, astonishing, excellent, fantastic, glorious, magnificent, sensational, spectacular, splendid, terrific, and wonderful. As I said earlier, before the Stromtank arrived, only at nighttime could my system reach its potential. But with the Stromtank my system reached its full potential regardless of the time of day. Even though Stromtank’s literature promised it would make this improvement, it took me by surprise. Having my system sound the same both during the day and at night took some getting used to. In a good way.
The only “problem” I ran into was that I couldn’t connect my 350 Watt per channel Pass Laboratories X350.5 power amplifier to the Stromtank S2500 and play it at excessive volumes. If I did, the Stromtank would shut down because it would become over-heated. This only happened once during my time during the Stromtank’s audition period. After it shut down I had to wait a while so the Stromtank could cool down. After that the Stromtank operated perfectly, and I could listen to music again, being fully aware that if I was to connect my power amp to the Stromtank, I should be very careful about how high I turn the volume of my system, and for how long I listen to a louder than absolutely necessary. Otherwise, the Stromtank performed as advertised, and without any problems whatsoever.”


Bowers & Wilkins Formation Duo Review

“First impressions were positive – a big and expansive sound stage was painted, and even with compressed material from Apple Music, a very enjoyable sound was presented, with fine rhythmic “foot-tapping” quality to the bass line on Dave Brubeck’s Time In (Apple Music Adaptive AAC streaming). Browsing through my Apple Music library was an enjoyable spree, the speakers taking on all genres and presenting a very detailed, rhythmic and enjoyable rendition.
Especially of note was the anchoring of female vocals in the centre of the soundfield and the texture of the plucked double bass (Ilona Knopfler, Live the Life, Adaptive AAC streaming). Vocals had fine projection, with exquisite handing of sibilants and the “air” surrounding the singer. The double bass showed lovely texture, with the leading edge of the plucked sound having fine articulation – one can almost visualise the singer and the bassist”

“I hooked the C 658 up in a system consisting of a NAD C 268 stereo amplifier that the company sent along for use during testing and Polk Audio L800 tower speakers. While the C 268 is conservatively rated for 80 watts continuous output into 8 and 4 ohms (20 Hz-20 kHz at 0.03 percent THD, both channels driven), it easily drove the full-range Polk Audio towers to a satisfactory listening level. Sources included a Panasonic DMP-UB900 Ultra HD Blu-ray player for CD playback and a Pro-Ject Debut turntable with Clearaudio Aurum Beta/S moving magnet cartridge for vinyl. The music streaming services I used for my testing were Tidal Hi-Fi, Qobuz Studio, and Amazon Music HD.”

Gryphon Audio Designs Zena Preamplifier Review

https://www.soundstageultra.com/index.php/equipment-menu/937-gryphon-audio-designs-zena-preamplifier
The Zena’s visual design and build quality, the beauty of its display, the attractive owner’s manual, the inclusion of gloves and polishing cloth, and the quality of its packaging all indicate that Gryphon Audio Designs is more concerned with delivering a premium customer experience than with wringing the last dollar of profit from its products.
Per Gryphon, each sample of the Zena is burned in at the factory for 48 hours; they say that the sound quality further improves after 40-50 more hours of use. The Zena comes with a three-year, nontransferrable warranty on parts and labor. That’s common for high-end audio components, but in my opinion, anything less than five years is too short.

Frankly, $269 earphones aren’t normally expected to do such things so well, but somehow the Cupids pulled them off. If you want a substantial taste of what serious high-end earphones are all about, without putting your budget in distress, look no further than oBravo’s Cupids. At their asking price they are not just a bargain, but a musical gift. “

Dan D’Agostino Master Audio Systems Momentum HD line preamplifier $40,000 Review

“I briefly switched DACs and used a single S/PDIF cable from the dCS Network Bridge to convey signals from the Roon Nucleus+ to the EMM Labs DV2. With the Momentum HD preamp controlling volume, I heard more air around Cassandra Wilson and Rickie Lee Jones’s voices and accompaniment, but a bit less midrange profundity. After realizing that the comparison was flawed due to setup constraints—I’ve since moved equipment around on my eight-shelf double rack so I don’t run into this problem in the future and sent the DV2 back for a major upgrade—I acknowledged that a valid comparison between the two DACs would have to wait.
When I returned to the Rossini DAC/Momentum HD preamp combo, revisiting Cassandra Wilson’s performance revealed a complexity of string tone, deep bass grind, and increased color contrast and depth that, compared to what I heard from either DAC alone, left me in awe. Adding the preamp delivered Rickie Lee’s creepy vocals with much more subtlety and intimacy, and markedly greater dynamics, even at low volume. I didn’t want the music to end.”
