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

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 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.

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've got a Quicksilver tube headphone amp, and for the money (under $1000), it is excellent!! Sounds great and very well made....

Think of Primaluna. The best value for money. 

It appears that I can't be wrong with QS monoblocks and I need to get at least 100 WPC amps.

@i

Yes you can go wrong but not due to the quality. Again, unless you are nearfield or in a smaller room, 100 watts on a speaker that's only 87dB in an average room won't be enough power. I would seriously consider replacing the speakers with something more efficient if you plan to work with an amp of only 100 watts. Otherwise if you try to push things a bit, if you want to rock out, you'll run the amps out of gas.

+1 @ knotscott

VTA is very good w/ great customer service. The VTA ST70 replaced a highly regarded high power amp. I am surprised at how good it sounds especially for the $$$. It is a bargain and a helluvan amp. I've had the 70 & 120 The 125 monos should have the same rich sound.

Hi ihcho
I´m a happy owner of a pair of 80W mono QuicSilver amplifiers for more than 25 years driving the Melior One speakers - in my secong equipment- and the sound and pleasure playing a Mozart Quartet or Kid Ory Blues is charming.
Power election it will depend on your speakers, but QS is an absolute bargain. 

I love my Horn Monos.  Quicksilver doesn’t play the “review game”, so he’s not sending out amps for free in return for good press.  Instead he relies on word of mouth.  I will say this; back in the day, Quicksilver was a darling of both TAS and Stereophile and reviewed very favorably against all the “giants” of the industry.

Purchased my Quicksilver Minimite Monoblocks  new and have owned them since 2006. I consider them to be some of the best sounding power amplifiers I have ever heard.  

Regarding their design, they are simplicity itself, using point to point wiring and quality transformers. Mike Sanders is also one of the most honest people in this business, and stands by his products.

yes.  and no

About five years ago I compared the mono 120s with the ARC 150 and I thought it was a tossup. The Quicksilver’s weren’t just good for the money, they were just as good.

My Mid Monos sound wonderful and are very reliable. I have owned ARC and Cary tubed power amps and they are easily in the same league soundwise.  If you need more power consider the V4. The capability to use different output tubes which both the V4 and the Mid Monos is great.  I prefer the sound of EL34 tubes to 6550/KT88s but you can use either in these amps as per your liking. 
BTW, The mid monos at 40W/channel drive my 89db speakers to more than adequate level and play as loud as the 100WPC solid state Belles Power Amp  I was using before. Tube watts seem more powerful and satisfying to me than solid state watts. I see there are some used  Quickliver 80w monblocks for sale at Echo Audio.

In response to reliability and service...   I have had a few tube failures... it happens.   The first time I called and Mike answered as he usually does and told me not to worry , probably no damage just replace fuse and isolate bad tube He was right, these amps are super reliable.  Mine have many many hours on them. I listen every night for a few hours.  All weekend long.  They see a lot of use  A LOT.   I only paid $1050 used,they were a little over a year old but honestly I would gladly pay $2100 for these amps new and still feel like it was the bargain of the year.  

Buy the 120 monos and be done.  
Buy once , cry once is what I always say. 

No

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….

Conversations evolve……roll with it….

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.

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,

enjoy

No.

So, who has lived with both and can articulate the sonic differences and similarities? Too many yes’s not enough information on sound. I am assuming the primary characteristics we are really interested in is sound quality. 

Mike Sanders of Quicksilver makes excellent tube gear! His mono amps are particularly fine! An easy recommendation!

I'm fine with amps that are total sleepers....there is nothing on those Mid Monos that doesn't need to be there.....ie, faceplate 

I'm listening to them as I type....huge wall of sound with my Forte IV

I know, I feel like I'm betraying Mike by not buying another Quicksilver amp....

I'll alway be a QS fan.... not selling the headphone amp either.

Yup, quality amps!

  They would not be in business long if they sold subpar and halfa$$ed components!

 

"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. ."

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

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 

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 own the M120s, and they are just phenomenal... I would put them up against any and all oncomers. 

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 need to drive 87dB speaker, so the power has to be at least 80Watts.

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

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.

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.

Yes

Yes!  I have friends that own Quicksilver power amps and the build quality, and sound is as good as ARC , VTL, etc!

Yes!

By what criteria?

I can think of objective factors such as the quality level of construction & design; parts quality, which would include transformers, capacitor, etc.
Then there are more subjective factors such as how they sound, especially in comparison to stated competitors.
Then, there’s durability, warranty, fixability, customer service, and price.

Yes!

Yes.
