Are Quicksilver power tube amps in the same league as VAC, VTL, BAT, ARC, ...?

I was thinking of 80W Quicksilver monoblock, but decided to go for more power.
My solid state amp is Plinius SA102 (class A 125WPC). Plinius works quite well with Gershman Grand Avant Garde (87dB). I listen to fairly loud and I don't feel lack of power, even though Gershman may enjoy more power. 
My room is not huge (about 15' x 7.5' x 30'). I sit about 10 feet from the speakers.
I contacted Mike Sanders and he said that they will have a new 100 WPC monoblock amps available in October. I am thinking of going for that amp, unless I find some sweat deals for used mono 120 or V4.
Thanks again.

I used tone a QS dealer. Truly great stuff. Felt his best are the mini monos. Those are the ones that Mike uses in his system.
QS does not spend a lot on cosmetics and the parts are not the best. For under $5K, you can’t go wrong.

If QS was as good as VAC or ARC at one fourth the price, both companies would have been out of business by now. 

Having said that, QS offers great value and excellent sound within its respective price bracket.

i have not auditioned QS. But experience with this kind of question in the past has always resulted in the support in your supposition. QS offers great value for the money, but not of the same level of performance. (No, the big boys are not there because VAC and ARC buyers are stupid and susceptible to marketing and biased reviewers).

So very true. Marketing and biased reviewers can only take you so far. Companies like VAC and ARC have built their reputations over a very long period of time by consistently providing high levels of performance year after year, while many flash-in-the-pan companies fizzled out after their 15 minutes of fame.
