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.

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.

Thanks all for the great input.  Lots of new tech for me to research.  Last question to anyone reading this.  Is 100 or even 80 wpc enough to fully handle Def Tech 350’s or Paradigm Millenia One’s?  Both are rated at 8 Ohms and not really efficient even though they are small.  Im after the best possible sound quality on these speakers at a reasonable budget.  I don’t want to short change them.  Thanks.

One more thought for anyone interested in weighing in. What is the weakest point of my system:

Emotiva BASX PT-100 PreAmp
Def Tech SM350 Speakers
Schiit Vidar or NuForce STA-200. (tbd) Amp
wiring is quality interconnects and 12 gauge 99+% copper speaker cable with banana post connections.

Keep in mind this is a home office closed in at 12’ X 12’ space. Sources vary from Rega Turntable to Apple TV or Amazon Fire streaming HD digital content.

Greatly appreciate any experienced input.

Ceiling is about 7’ tall with drop ceiling.  Tiles are fairly sound absorptive.  The SM 350’s are on the small side but very detailed and wide range.  I also have a small sub to augment.  My seating location is strategically located in a corner where sound is balanced.

Thank you all for the great advice.  I can see I have more research to do.  Fortunately I’m not forced to get something right away, so I can take my time to make the right choice.  Right now I need to decide if it will be worth the investment to upgrade from the Adcom 545 mkii up to the Schiit Vidar.

I am planning to invest in a Quality amplifier that I can stick with for many years.  As digital sources and preamps change, I can stick with the quality Amp.  So I am not aware of an all in one solution that would make sense for me.
