"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."

The concise conclusion to John Atkinson's Measurements sidebar: "All I can say is 'Wow!'"
In a Follow-Up, Jim Austin wrote of using the Benchmark processor with the same company's AHB2 power amp—a combination of high source output voltage and modest amplifier gain that he describes as "optimal for minimizing noise and distortion"—and reported hearing "richer and more interesting" reproduction of very subtle details.

"The benchmark combination offers a full range of equipment that can hardly be topped, leaves nothing to be desired in terms of sound, and meets professional requirements without any ifs or buts."
"The HPA4 has the HIFIMan one hundred percent under control, eliciting neutral timbres, tons of spatial information and crisp dynamics."
"I connected everything the household had to offer in terms of speakers - Spendor S3 / 5, Ayon Seagull / c, Quad ESL57. It goes without saying that the American coped with the dynamic boxes with ease. But even the quads, which have some meanness on the part of their impedance, did not pose a challenge for the amp."
"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."
