LJM L12-2 New build Need a guide

Since have an good quality 500w smps from failed Dclass project laying around for some time. Now I want to use it to built HQ amp with xlr inputs that would be used both for home-FI use and small parties like birthdays and so..

Supply is +-55v
Looking for stereo amp, but if it could be made so can be used in bridge mode too, it would be great.
Also would like to use all quality components.
Am going to buy those in a kit so please recommend supplies in EU if think I should replace any.

Here is a link of supply.
