"Many people I respect had lauded the DAC1, and I was interested to hear it in my home. Many reviews of the DAC1 had mentioned its headphone amplifier but had said little about it. Being an avid headphone listener, I wanted to see how well the DAC1 would stand up against my usual headphone amplifiers."
"Since then, months have passed during which I've used both the DAC1 and ADC1, and I can say with confidence that Benchmark’s reputation is well deserved. The three most important elements of any product -- build quality, sound quality, and customer support -- are all present in their designs."
"The ADC1 is the most powerful recording tool I've ever used, and is probably overkill for the casual recorder. But if you have a serious vinyl collection to archive, or are setting up a small digital recording studio, it should flawlessly perform to high standards. The DAC1 will have a wider audience and can serve many functions: headphone amp, digital preamp, and, of course, D/A processing."

"Thanks to the special, discrete analog circuit/relay attenuator, this may be the most transparent line-stage preamplifier in the audiophile world."
"If you got a great-sounding source, the LA4 presents the audio in its original state — with gain or attenuation to the amplifier. I have never heard such low-level detail from a pre."
"The better the DAC, the better you hear it through a quality amp and speakers. It is quiet as a top-notch DAC, with S/N exceeding -135 dB and, feature-wise, it comes with unbalanced/balanced I/O and a really slick user interface."
"I use the four-input LA4 for audiophile A/B testing of DACs, monitoring my Hi-Res home recording/editing/mastering projects, as well as just listening how good my vast collection of 24 bit and DSD music sounds through an accurate amp and speakers."
"A steal at $2,500!"

"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."
