Aram,
That is a rare and wonderful VMPS speaker. I am a VMPS dealer, and we often use the AMPZILLA Monoblocs with the larger Floorstanders.
In a couple weeks, we will be exhibiting with the VMPS RM50 and the newer AMPZILLA 2000 Second Edition Monoblocs (300/500wpc each)
James Bongiorno just won Absolutes Sounds "EDITORS CHOICE" Award for that very amp. Brian Cheney used the original version in voicing your speaker and the combo won "Best of Show" (for James Bongiorno and his amps) several years ago.
I have also had many customers using the bigger and newer (squared version) BRYSTON amps. Others swear by the NuFORCE Monoblocs which sound markedly different. Your speaker will certainly allow you to hear the distinct and subtle differences between components.
On a "warmth" scale they might be ranked as below.
AMPZILLA slightly warm, but still exceptionally detailed
BRYSTON (squared versions) less warm
NuFORCE least warm
If you need any assistance in "tuning" your pair feel free to e-mail me.
