"The DAC2 DX had some of the lowest distortion of any DAC we have ever tested"
"Listening to my music collection via USB was a pleasure with this DAC. It had a very musical sound, reminding me of a Class A triode tube amplifier. When you check out the bench tests, you will see why."
"IMD was less than 0.001%, so I have to say, “Excellent”. See any peaks at 14 kHz, 21 kHz, etc? Neither can I. Now we know why the DAC2 has a bit of Class A triode in it. When peaks are present, they are only at the second harmonic, which is the triode signature."
"The DAC2 is one of the few D/A converters that can handle intersample overs without DSP overloads or analog clipping. DSP overloads occur in most DACs and these cause bursts of non-harmonic distortion. Some DACs avoid the DSP overloads but still exhibit analog clipping of intersample peaks. In contrast, the DAC2 cleanly reproduces intersample peaks. This seems to be a big issue from an audibility standpoint when listening to CD-format and MP3-format sources."
"I have used Copland’s Fanfare for the Common Man as a test track more than any other. That is because it has everything: tremendous dynamics (it’s an early Telarc disc and there is no compression), very loud percussion, blaring brass, and whatever else you want to throw in there – it’s just a great recording."
"The sheen of the gong and bright overtones of the brass were stunning through the Benchmark DAC2 DX. This may be an old DAC in HiFi time, but it is certainly up to date in sound."
"The Benchmark DAC2 DX represents a product that was initially released several years ago. They perfected it over that time by small changes and addition of features. The result is a DAC that has virtually inaudible distortion, and a full set of codecs, all at a price of less than $2,000. This compares to some other DACs that are new and unproven in reliability. It makes sense to put aside that, “Got to have the latest and greatest,” attitude that most of us have, and consider a DAC that has had several years to work out all the bugs and really deliver a superior sound."
"For my money, the Benchmark DAC2 DX represents one of the best values in high end audio today."

"Since the HPA4 arrived, I have rediscovered so many of my favorite works all over again with improved detail retrieval dynamics and transparency that it’s hard to pull myself away!"
"It drove my power hungry Abyss Phi TC headphones with complete authority, but it was still dead silent and nimble enough to amplify my easy to drive Focal Utopia headphones."
"Rarely have I come across such a wonderfully revealing amplifier that can drive many different types of headphones so darn well! The solid build construction and various controls make the $2,995 price tag seem a bit low based on the other headphone amplifiers in this market space."- Peter Pialis, Headphone.guru
"Benchmark Media Systems’ LA4 preamplifier presented an utterly realistic reproduction of what was contained on each recording I played through it -- and weak recordings stood out more than usual. The LA4’s clean, analytical abilities are unmatched by any similarly priced preamplifier I know of. The LA4’s touchscreen brings it up to date with current user interfaces, and permits functions, such as balance control and muting at the device."
"If you want a preamp that editorializes, look elsewhere."
"If, like me, you value a high-resolution, totally neutral musical performance, add a Benchmark LA4 to your system, particularly if you already own a Benchmark DAC."

"You’ll have a tough time finding a cleaner, quieter, more transparent line amplifier and headphone amplifier anywhere, at any price. I found it to be a new reference. Once I heard it, I could not live without it, so I purchased the review sample. The HPA4 deserves my highest recommendation."
"The HPA4 is the latest product from Benchmark Media Systems, an upstate New York audio manufacturer. Benchmark calls it a headphone amplifier, but it’s really two products in one, combining the LA4 Line Amplifier introduced in 2018, with a headphone amplifier. It is also based on the same THX Achromatic Audio Amplifier technology used in Benchmark’s acclaimed AHB2 power amplifier."
