Quicksilver Mono 120 vs. Quicksilver V4

My friend replaced his ARC HD220 ( hybrid ) with the QS 120’s. With his Proac D48r’s they are outstanding!

I have had the Quicksiver M120s in my system for going on 2 years, replacing a pair of 20 year old VTL MB125s that were starting to have issues and love them. I use them with a Lamm LL2.1 preamp powering a pair of Wilson Audio Sophias and do not miss the more than twice as expensive VTLs. As far as the differences between the M120 and the V4s would be a question for Mike Sanders at Quicksilver, who I have found to be a breath of fresh air and very accessible, give him a call. Also the M120s use 2 kt150s and the V4s use 4. Enjoy the music.

Forgive me for waxing nostalgic but I ran a pair of Quicksilver Monos for many years (damn, I can't remember what preamps I coupled the Quickies with).  At the time I lived less than five miles from Mike Sander's house, so it was no problem getting silver-quick replacements for those soulful if highly neurotic 8417 output tubes. Don't look at them funny!  At any rate, I eventually lost my patience with the ever-increasing cost of buying matched 8417s and bought a Primaluna Prologue One integrated.  Been happily out of the amp trade-up game ever since.

I find it weirdly disloyal in some way for you to have moved from Quicksilver after all those years. Did you compare them to the PL and decide against them?
