Grip Beyond Anything I've Ever Seen Or Heard

The 350 controls the woofers. And when I say control I mean full on domination. Grip beyond anything I've ever seen or heard. Normally an amp will have a speaker on a leash but these appeared to be physically joined at the hip.

The sound from the 350 is brutally honest. It is simply a gain on a wire, all it should be and all I wanted.

"The right amp at the right time."
"The eloquence 150i is a master of space and time... with a rock 'n' roll heart beating inside that compact chassis."
"The 250i behaves, unapologetically, in exactly the manner you’d demand of any high-end unit with vast reserves of power: with grace and guts. And eloquence."
"The Audiant sound is authoritative and clear. It’s dynamic and airy, with resolution that allows you to hear deeply into the music."
"The 150i was so grain free, so natural sounding, so musical, and refined that it did absolutely nothing to give away that you were listening to either solid state or tube."
"The DP32 and 100p is one of those famous combinations that lets you get on with enjoying the music."
"The 250i is pretty close to my dream amp!"
