The input voltage amplifier configuration allows balanced as well as single-ended inputs, and balanced feedback to be used. The amplifier is fully balanced throughout, including the output transformer.

The overall topology of this 110Wpc push-pull amplifier comprises an input cathode follower (6922) and two differential plate-loaded voltage amplifiers (6922s) in cascade, followed by a driver cathode follower (5687WB) direct-coupled to the output tubes (KT88). And my easy-to-drive Alón V Mk.IIs sing quite happily on 100Wpc, thank you very much. Both of these guys are very picky and can afford anything on the market.Ģ) Sonic Frontiers' President, Chris Johnson, claims that the designs of the Power 2 and 3 amplifiers are so close that, if one owns speakers that require no more than 100W per side, he would not be able to tell the difference between the 2 and the 3. Aside from the fact that I enjoy reviewing four-6550/KT88-pentodes-per-side tube amplifiers because they tend to be very versatile and cost-effective, I was especially interested in the Power 2 because:ġ) I have two well-heeled audiophile friends who constantly rave about their Power 3 amplifiers. Ultimately, I was able to squeeze the Sonic Frontiers into my review schedule. "Well, let me discuss it with Wes Phillips." "But this is a direct trickle-down from our Power 3 200W monoblock! What we've done is make a 110W stereo version on one chassis. Johnson's facial expression resembled that of the young executive who's just been told he's not getting the promotion he'd expected. It looks like a very interesting design, but maybe you'd be better off having it reviewed by someone who could get to it a bit quicker."

"Uh, well, actually, I have quite a full plate of review samples in-house, so I really wouldn't be able to get to your amp for quite some time.
A review sample will be ready for you in two weeks. So you're still looking for your dream amplifier under $5000? Well, here it is! The Sonic Frontiers Power 2. "Hey, Bob Reina! I enjoyed your review of the Cary SLM-100 amplifier in the May 1996 Stereophile. I was attacked by Chris Johnson of Sonic Frontiers at HI-FI '96.
