Highly recommended! Mr. Panson know his stuff very well and this is one of the rare DIY PCB designs that is actually very good. I believe from own experience PCB design add's (or degrade) more to audio design then choice of components.

It is no surprise this kit has such an extraordinary low THD levels, since again the PCB design is excellent, and fits most of the rules to achieve low distortion

With kind regards,
Bas

How about the sound quality ? How good are the LME series based amps ? Why don't more people use them as opposed to something like the 3886 types ? I have ordered a pair, But still waiting for a shipping conformation and more information... from Mr. Panson

I have used the LME driver chip in a very successful commercial design. THD spec and sound wise it is very hard to beat. The LM3886 has it's own place, but superior results can be made with this driver IC and a good discrete power stage. I think Panson pretty much nailed it down, and is about the best you can get out of it.

With kind regards,
Bas

Sebastiaan, Thank-you for this information, I now feel inspired to try to build a amp based on those pcb's once I get them.

Strangely I also didn't see more kits based on this chipamp. Looking for a higher power version of the one made by Panson (at least 250w/4 ohm).

IC is out of production. I got 24 of the last distributor stock but no boards are stock. Panson board had good reputation but required 5 leg internal diode transistors, so not for the bargain basement type. Last I checked his webstie was under maintenance.

You may find this to fit the bill: Modulus-686: 380W (4Ω); 220W (8Ω) Balanced Composite Power Amp with extremely low THD
