"It’s ... been a while since I have been this excited about an audio product."
"I do have a good queue of products that deserve a review here, especially in the headphone department: Audeze LCD-2C, Quad Era-1, Brainwavz Alara. Hopefully I will get some time for them as well. However, in the meanwhile I am using them to test this wonderful wonderful headphone amplifier."
"I like the touchscreen and the implementation. It’s fast and easy to get used to."
"It’s the first time when I have heard the headphones mentioned above to their full potential. In the first minute my jaw dropped ..."
"This is the fastest and the most controlled bass I have ever heard. It goes deep, it’s organic when it needs to be, but it doesn’t linger at all. It’s controlled by an iron fist. The punch is really really fun and strong."
"The midrange is really pure and lively. The instruments and voices have vibrating, lively and pure textures."
"The treble is really extended, very detailed and sparkly. It doesn’t have any touch of brightness, but it does brighten up the place in a good way if you know what I mean."
"The level of detail is amazing on HPA4. I seem to discover other sounds in some songs that I did not notice before."
"The voices are incredibly pure and textured. Depending on the artist and the song, the voice can sound incredibly pure, stammeringly clean and extended, but also guttural/throaty in other cases."
"When you talk about natural sound, about emotion in this domain it usually means that the audio component adds some coloration that give a more natural tonality, more weight to the sound, more present voices, less harshness, etc. In this case the emotion comes from the purity of the sound from the fact that HPA4 completely removes itself from the system."
"From my perspective this is the best headphone amplifier I have ever heard. It’s no competition really."
"It’s not cheap, I can give you that. Is it worth it? That is up to each and every one of you, but if you really want the best amplifier out there, an end game amplifier…this is it."
"There are many things that come into play when putting together a hi-fi system, one of which is synergy."
"After the arrival of the Benchmark Media Systems AHB2, I immediately thought of the matching HPA4 that colleagues Jaap and Yung were very pleased with."
"The key question, of course, was whether the HPA4 would really provide an audible improvement."
"Well you bet! The synergy between preamp and power amplifier is nothing short of magical, not to mention the DAC3 B that I got from importer Helios for the occasion."
"Not only a few curtains disappear, the whole window is gone."
- Geoffrey Vanhouwaert, Alpha-Audio
"The Benchmark AHB2 is a very fine sounding, easy to live with, zero-maintenance power amplifier that has enough power for most systems. If more power is needed, two amplifiers configured for mono can provide it. The decision to purchase the review sample and make the Benchmark AHB2 a new, long term reference took over a month of listening and comparisons."
"The outstanding musicality of the Benchmark AHB2 takes some time to convince the listener of its wholly musical presentation. This subtle excellence assures long term satisfaction."
-10 Audio, Perfect 10 Award
Alpha-Audio.net tested 10 DACs side-by-side. Only one received the "Alpha-Audio Approved" award. That DAC was the Benchmark DAC3.
"Are you looking for the best DAC (d/a converter) in the price range from 1500 euro to 2500 euro? That’s great! Because we’ve put ten beauties side by side. And we tested it live on camera for you."
"It was incredibly instructive to put so many converters side by side. We clearly hear differences - and the viewers could as well."
"One of the models we all agreed on is the benchmark DAC3. This is a delicious musical product. Virtually no coloring, nice stereo image and plenty of inputs."
