Class D Amplification Announcement


After 60 some odd years of disappointment, Class D has finally arrived. As per The Absolute Sound’s Jonathan Valin, the Borrenson-designed Aavik P-580 amp “is the first Class D amplifier I can recommend without the usual reservations. …the P-580 does not have the usual digital-like upper-mid/lower-treble glare or brick wall-like top-octave cut-off that Class D amps of the past have evinced.”

Past designers of Class D and audiophiles, rejoice; Michael Borrenson has finally realized the potential of Class D.

If you started driving in the early 1960's, you know what a crappy car is and you know the worst car you can buy today is leagues better.  Our stereo equipment today has gotten so good for knowledgeable enthusiasts it's also hard to buy something poor like we listened to 60 years ago, relatively speaking to the state of the art that existed then and now.  Unless we listen to every piece of equipment, for us average listeners reviews are mostly what we got.  It would be nice if every review could give an absolute answer about relative value to competing equipment.  Sometimes the reviewers compare, but more often they don't.  I seem to think it happens more with lower priced audiophile speakers because like in cars, it's easier to design a $200k Ferrari in some ways than to bring a high percent of that performance in a $20k car.  I think reviewing equipment is an art and what I've learned is that reviews are a good guide but reading the review is also an art where if you read enough of them you get more insights into what technology and equipment is really good and a good value, too.

Just got my AGD Audions back after they were upgraded to the latest revision-MK III. The power supplies were greatly improved. Before the upgrade they were not very good at powering my difficult to drive Quad 57s.

Now, they pick up the Quads and dance them around the room. Wow, what a difference! I was considering other amps but no longer. Can't imagine anything better.

JV is confusing Class D amps with poor digital playback (usual digital-like upper-mid/lower-treble glare). Overall, Class D amps don’t sound like that, to the contrary, they are flat and artificially smooth, and unresolving.

FWIW, I have heard both examples. The upper mid glare is usually on cheaper examples. 

My Peachtree Pre/ Dac and Gan 400 Amp has about 100 hrs. of use....For $ 3500 for the pair...I haven't heard a combo so Musical...so Real...so alive ...so good for under 10K....darn close to AGD sound which is the best I 've experienced .  You're 95% there for a whole lot less $$.
