"After just a couple of minutes of Thrasher Dream Trio, a jazz album featuring drummer Gerry Gibbs, pianist Kenny Barron and bassist Ron Carter, I realized, "I'm really enjoying this!" I didn't hear any of the kinds of flaws that would normally distract or discourage me when first "meeting" a speaker. No obvious "cupped hands" coloration from the woofer. No boom in the bass. No major frequency response anomalies. No edge, grit, glare or grain. Just really good sound."
"Anyone who needs to be sold on why high-end audio is worth the expense would probably be persuaded if they hear saxophonist Gene Ammons' recording of "But Beautiful" through the SMS1. You get a gorgeous, almost glowing rendition of Ammons' big, romantic sound; portrayals of drums and piano that sound accurate and realistic without sounding over-realistic, and a natural sense of space that captivates you without trying to wow you."
"If you're looking for a high-end bookshelf speaker -- or even just for a good speaker, period -- you should give this one a listen. I think you'll realize, as I did, that after the first couple of tunes, you're blown away not by how spectacular the sound is, but how good it is."

"RMAF 2018 was really good, with significant numbers of attendees, and more new-product introductions than I remembered ever seeing there."
"Led by engineer John Siau and based in Syracuse, New York, Benchmark Media Systems has built a sterling reputation for making compact, well-engineered, moderately priced electronics that challenge the state of the art, both on the test bench and in the listening room."
"What I took notice of were the specifications: total harmonic distortion of less than 0.00006%, and a signal/noise ratio exceeding 135dB from 20Hz to 20kHz."
"If those claims are true, and there’s no reason to believe they aren’t -- Benchmark gear has always performed as specified on the test bench -- the LA4 should be about as transparent-sounding a line-stage as you can find at any price."

"Benchmark describes its product as a 'reference Stereo Headphone Amplifier and Reference Line Amplifier with Relay Gain and Input Control', which should give you some idea of what's going on here, but only hints at the fact that this is actually two completely separate products packed into one relatively compact unit."
"The headphone section is powered by a power amp from THX, employing the same AAA (Achromatic Audio Amplifier) technology first used by the company in its AHB2."
"Benchmark's line amplifier uses relays for input selection, gain control and muting while four independent 256-step attenuators ... feed the the headphone ... and preamp outputs."
"As PM notes in his Lab Report, this design gives the HPA4 not only outstanding performance, but also rather impressive - to say the least - signal delivery."
"All of a track or two should do the trick, as whether with revealing headphones ... or used as a preamp, the HPA4 simply drops jaws with the sheer impact, openness and vivacity of the way it plays music."
"It was one of those real 'performer in the room' experiences and I was instantly transported back to the time I spent monitoring the recording as it was being made ..."
