B&K ST202, modify or replace

I’m currently using a B&K 200.2 and have this ST202 on center channel duty. I would like to recap this amp and possibly use it as my dedicated 2 CH amp. I’ve read up on the mods to this amp, it looks like a fairly easy amp to work on and I would like to explore the possibility of really taking this amp up a few levels.

I’m confident with my soldering and fabrication skills, I just don’t know what current parts to use and replace to make this amp shine again.

I’ve contemplated the used market, possibly a McCormack DNA .5 or .125, maybe I can take this 202 even farther than those. ...not sure.

I’ve looked into the MC mods and the prices aren’t too bad but being a diy’er I’ll always look at doing things myself as well if possible.

I’m definitely looking to increase clarity and dynamics while keeping a low noise floor.

All input appreciated.

I don't find these 2 amps in the same league of one another.  To be fair I haven't heard an ST202, but at one time I owned a Reference 4420 and for my taste, the DNA .5 would slaughter it.
The B&K was soft & pretty, kinda laid back... The difference in dynamics and detail is where the difference lie. 
If you increase power supply capacitance,  use better caps throughout the boards, I'm sure that you improve it, but I would not expect the B&K to ever overcome the DNA.... hope this helps, Tim
