Default High Power Chip Amp

Is there a design here for a high power Chip Amp? Say three or four chips in parallel. The single chip amps just doesn't quite cut it for me or my Dynaudios... I have seen several from Asia on E-Bay but am extremely hesitant to order from China because of all the rights infringement going on over there.

Thanks for any suggestions,

Mark

Alexw88 has made a triple LM3886 board and I have made a bridge unit so you can connect 6 pcs. of LM3886. Check my sig about BPA300 Round 3 group buy.

More info can be found in the application note AN-1192

Am still trying to figure out if I can aquire all the same SMT compoments over here or not without having to buy huge quantities... The project looks really good though, I especially like the idea of the Lundahl transformers!! I can get those out of Canada.

For that much power, it really makes sense to go with a hybrid digital. The initial and operation costs would be much lower.

or go fully discrete or use LME49811 + discrete triple EF output stage.

Guys... and Gals,

I am only wanting to build one because it's a project I have not done yet. I've always been intreguied by the thought of those chips in parallel and I once had the chance to sit and listen to the Rowland amp for a while which was a definite knock out!!! Digital... sure... but later on when it's perfected.

The new hybrid digitals (which are much different from the pure digitals) are very easy to get working and get you smug, not smog.

star882 is on the quest to bless the entire world with class D amps. I don't know, if he has a financial interest in it, but he wants to bring switched amp luck and happiness upon all solid state and chipamp affectionates, whether they want it or not.
