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


I see that VAC, VTL, BAT, ACR power tube amps are almost twice or more expensive than Quicksilver power tube amps at the same power ratings.
Are Quicksilver power amps as good as twice or more expensive brands?
I am considering power tube amps with 80, 100, or 120Watts power ratings and I just wonder.
I don't have much budget (under 5K) and my choice is either new QS or those other brands used.
If not QS, which brands are best bang for the buck for power tube amps?
I need to drive 87dB speaker, so the power has to be at least 80Watts.
Thanks for your input.

Yes!  I have friends that own Quicksilver power amps and the build quality, and sound is as good as ARC , VTL, etc!
P.S. I have QS Mono 60's and they sound glorious. That said, I have not compared them to the others, but from what I've heard they're quite competitive, especially if one changes the caps to higher level caps.
The Tubes4Hifi Vacuum Tube Audio (VTA) tube amps are excellent bang for the buck. Their service and support is wonderful, and they have a significant following.

Their factory wired M-125 monoblocks (125wpc) are $2700 plus shipping, less if you buy in kit form.

Unless you are nearfield or have a smaller room, you'll need more power than that! But to your OP question: 'Yes'.
