Red Wine Audio Isabellina HPA
“ So where do I begin? I say this because my file with my impressions was lost when my Dell computer took a dump a while back. I have since transition to an 21.5 iMac so I am having to do a new write up of the Isabellina HPA ( http://www.redwineaudio.com/products/isabellina_hpa ) and the Signature 30.2 ( http://www.redwineaudio.com/products/signature_302 ) My first Isabellina HPA was...” --mrarroyo
HeadAmp Blue Hawaii SE Electrostatic Amp
“ About having to wait a while to get it is not that bad because I ordered mine August (1987) and it finally arrived yesterday (07/08/2012)... I got the Alps RK50 upgrade with it. Only joking I ordered it last year because I was only 5 in "87" but anyways waiting a year isn't that bad because it's here now (it actually came 3 days early). It's not that long to wait at all and in the mean time...” --Snake Eyes
Meier Audio Concerto
“ Overture The Concerto, the newest amp from Meier Audio, is essentially equivalent to the top Meier, the Symphony, with a less features and a few tweaks. As such, it employs Meier’s Active Balanced Ground topology, and includes his famous Crossfeed image enhancer (which is supposed to be improved from the Symphony, and as always is defeatable), and a gain switch. That’s it for “features” –...” --Skylab
NuForce Icon uDAC-2 (Black) USB DAC (24bit/96kHz) and Headphone Amplifier
“ I just completed a full review of the uDAC-2 with measurements on my personal blog. Some of the results were bad enough I contacted NuForce before publishing my review to make sure I didn't have a bad DAC. They verified my results and confirmed my uDAC-2 was "within spec". At their request, I've included their comments in my review. I plan to be testing other similarly priced USB...” --nwavguy
Ray Samuels THE SHADOW
“ Not only is Ray a great guy to buy from & deal with, he makes an outstanding product. The Shadow is everything he says it is & more. Extremely transparent, it doesn't color the sound at all. It gives your IEM the energy & power they need to spread their wings and FLY. Paired with my Westone 4, which are already pretty damn amazing, it opens them up...” --jamesta
Arcam rPAC USB/Headphone DAC
“ Hey guys, I have seen this little box recently and it intrigued me a lot. It has an impressive build quality. It has a very thick aluminum case and it feels like a tank can get over it and wouldn’t hurt it. Ok…Now I am curios..would it hurt it? Why am I thinking of this? Because of this crazy video: Hmm…All i need now is a tank… Does anybody knows a...” --dan.gheorghe
Benchmark - DAC-1 Black
“ Caution: Anything I say in this review is what I think of the DAC and according to my taste as a audiophile, you should always be aware there's a degree of YMMV in any review. Also, I did most of this review using speakers but I will comment on how it sounds with the Beyer DT880 600 ohm edition. Introduction: I've experienced and purchased many pieces of equipment in my short...” --NinjaSquirt
Musical Paradise MP-301
“I purchased a sample of this amp to review. Normally I don’t do that, but in this case I did, for two reasons: 1.I wanted to try a 6V6 based amp, to get a chance to try this type of tube 2.It was CHEAP! Holy poop, is it cheap - $200! The MP-301 is actually transformer-coupled. And indeed, it had no problem driving low impedance headphones. Zero hum at all. It’s surprising enough to find an OTL...” --Skylab
Audio-gd Phoenix
“ Lots of ink has been spilled about this amp already. The “big thread” on the Audio-GD Phoenix is VERY long – so long it’s only useful as a running dialog about the amp – reading through it to glean information has become very difficult. But it shows that there is a lot of continued interest and excitement for this amp, which is in my experience somewhat unusual for an amp that sells for more...” --Skylab
JDS Labs C5 Headphone Amplifier
“ It's a solidly made piece of gear that sounds very, very good. To my ears, at least as good as the O2 - a well known reference by now. Perhaps slightly more openness and clarity. The size is very reasonable; about 100 X14X60 mm. Sound is smooth, soundstage is full (though not overly so); no harshness at all. Only issue for me is too few steps on the ...” --zazex
