$4000 to spend on a SS power amp - help me choose


Audiomeca Mephisto II CD Player
Emotive Audio Sira preamp
VMPS Super Tower R / SRE (ribbon tweets; ribbon mid panel)
Acoustic Zen cables everywhere

I own a Graaf GM 200 OTL as my first amp; the SS will be
a back-up or possibly drive the bass in a bi-amp situation w/
the Graaf & a VMPS active crossover.
