Amp upgrade advice


I am looking to upgrade the amplifiers in 2 of my systems and could really use some advice from experience audiophiles.  I’ve laid out the current systems in my office and kitchen below.   I am happy with the pre-amps and speakers in both rooms.  They are both augmented by subwoofers.  I am interested in upgrading the Amps.  I’ve listed the amps I currently have.  I’m planning to sell thee current Adcom’s to fund upgrades with a few extra dollars.  My research is pointing me to the B&K Reference 125.2 amp.  Both rooms are smaller with smaller speakers so I am thinking quality Amps rated at 125 W should be plenty.

I am asking for your advice:  Am I on the right track?


Office. (12’ x 12’   Closed room)
Pre-Amp. Emotiva BAS X PT-100
Speakers Definitive Tech SM350

Kitchen ( 10’ x 20’. With one open side)
Pre- Amp. Emotiva UMC-200
Speakers Paradigm Reference Millenia One

Amp’s to sell?
Adcom GFA-555 MKII
Adcom GFA-545 MKII

Looking at B&K Reference 125.2

Thank you for any advice.

Benchmark is a breakthru in technology

Schiit Vidaris a breakthru in pricing for SQ - has some interesting modules in it too

Lots of good Class D amps out there too

- you do not list a budget
I wouldn't touch Class D  with a 10 foot pole.  Why not look at Emotiva amps, they would match the preamp in one of your systems and they seem to be pretty cheap.
In terms of budget, I’m hoping to get $400+ for the 555ii and $275+ for the 545ii.  I’m hoping to trade up for not much more than 150% of trade ins.  I’m hoping downgrading power on the 555ii will yield higher quality for the size of my speakers.
