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.

The 4420 is roughly the same as my 200.2, the 202 is a little less dynamic and doesn't seem to drive larger high demand speakers with as much authority...the 200.2 can provide 75 amps and I believe the 4420 does as well.

I've eyeballed the Parasound 2250 V2, and both McCormacks, DNA .5, & .125. My gut says the McCormack would be the nicer amp but haven't heard them, only about them.

Used prices on all 3 are attractive, I guess I have my sights set on the .5 or equivalent, and/or better.

I don't believe I need more than what the .5 provides, but more is always welcome...some amps work as good with lower ratings.

I'm driving Polk SDA SRS 2.3 TL speakers and they can be power hungry. These speakers are freshly recapped and while the 200.2 works well with them,  I believe it's time for a step up in dynamics. 

I also am using a VTL 2.5 preamp so impedeance matching may play a factor.

I don't plan on driving these much past reference level, im after more clean sound at slightly raised volume levels than all out foundation shaking.
