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.

My QS Mini-monos are my favorite amps and I've owned quite a few different amps. Not much to look at but they sound sweet. . 
I own the M120s, and they are just phenomenal... I would put them up against any and all oncomers. 
Absolutely!!!   I have had my Mid Monos since '15 and they are the best sounding amps I've ever owned.    They are a huge bargain compared to a lot of other amps.   If you owned Mike's new 120 monos you would not be disappointed.   

I am having a new amp built...  why?   I don't know, late mid life crisis I guess....  one thing is certain,  I will never sell those amps.   In fact I just picked up a preamp and tuner to pair with them in a second system .

I have sat here many nights listening, saying to myself, why am I getting a new amp?   They are that good for the money.  
I recently bought the Quicksilver Headphone amp.  It is literally built better than most power amps .   It is a tank,  like a 2/3 size Mid Mono.

Its awesome !!!  All Quicksilver gear is point to point wired, heirloom stuff that will outlast the owner.   Dont let the plain looks fool you, it is high quality

Function over Form: my favorite type of gear. And the builder has passed the savings to us. Thank You Mike Sanders!
