Hi Guys,

Yes I'm very late into this Class D bandwagon. Got myself a used set of UCD 400
AD version & am wondering what can be done to improve the sound further.
Search the forum here did manage to find some threads but ???? Found one
hybrid thread but no schematics. Would appreciate your thoughts on this.


Thanks

I am sure there will be people suggesting swapping the caps etc., but I would really caution against it. The Hypex modules are pretty well designed, and while it is very easy to make them worse (for example by introducing longer leads on components), it is very hard to make them any better than they are.

The only possible change I can suggest is adjusting the gain (by changing the feedback resistors) to optimize the gain structure of your system.
