Of the three amps I find listenable around here my version of the 3886 comes in last by a nose. It is so close to number two I believe optimization of the 3886 may make it number two. The one I use was built with stock on hand and is not really optimum. On the other hand both #2 and #3 are some ways from the #1 amp. Also, #3 is still ahead of anything else tried in the marketplace... about 100 other "audiophile" amps and even some common stuff. As for common, the Insignia at Besty Bu is pretty darned good and very cheap. Please, this is just an opinion. Thanks.

so what is the cheapest consumer A/V $/W with hackable analog power chip amps?

my quick look shows a Sony STRDH740 - "7x145 W, @6 Ohm" for $300 msrp - of course they are playing games with the rating - 240 W rating for the mains power??

whats inside? can we parallel 3 of the channels per side for a OK stereo amp? parallel+bridge for (likely weedy) monoblock?

maybe look for more realistic rated lower power chip amp based A/V amp

Pioneer VSX-822-K 5x80W at least claims a 450 max line power - $230 from Walmart

The TDA7293V came in years after I had done testing. Clearly, that one is the best sounding by quite a bit simply using the data sheet design. The very cool things are higher voltage and designed with the intent to run multiple chips in parallel for greater current. Have not implemented my specific design using this chip but is on the to do someday list.

As for higher power, I greatly prefer more channels and a single amp connected to every speaker instead of trying to make a powerful amp pull a huge train with all those losses.
