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.

They are great amps!
last I read, the transformers are all hand wound ,and most of the wiring is all hand wired not on boards,

Thanks for all responses.
My question was mostly on the sound, and then build quality and parts, and then probably their services.
It appears that I can't be wrong with QS monoblocks and I need to get at least 100 WPC amps.
I will look for one in the short future.
Was picking up a really nice set of speakers from dealers home in Malibu…. while his preamp was a top of the line ARC, his choice of amp was Quickie….

Nice….
