Quicksilver amplifiers

Hi
Anyone familiar with Quicksilver amps?
What are they like?
Any extraordinary Atriburtes with their sound?

I picked up a pair on that auction site, reasonable. They're the Mid Mono amps, mono-block amps.
I like it that they can take many different power tubes and have a built in bias tool on board.

I have never heard ANY Quicksilver amps though.

Any comments appreciated.

One more thing,I own a Minimax preamp that has a high gain,would it be a simple task for a local electronic repair person to lower the gain on the pre?

Thanks!

Little late for wondering if they're any good, isn't it? :scratch2:

I didn't read the OP as looking for information to be used to support or prevent a purchase. He stated upfront that he -already did- buy a pair.
Seems to me he was asking anyone else on AK about their experience with Quicksilvers.

What's wrong with that ?
 
I lived with a pair ot the original 8417 based mono blocks for a few months. Loved them, very open, wide soundstage, great overall sound. 8417's tubes are getting hard to get, but not impossible. If I ever acquire another pair, I would NOT mod them for other tubes, as I have read mixed reviews of the results.
 
I used to own a large 150 pound amp that was a prototype quiksilver built.
It had 8 EL84`s per channel and about 200 watts I surmised , maybe more.
It was the best amp I ever owned until a power transformer blew.
The guy I sold it to really loved quiksilvers. I did too.

I've no personal experience on this one... but...
Last fall a fellow local to me was selling a set of modded ( to EL-34) Quicksilver 8417 amps. I called him... we talked. He was very honest and stated that the amps lost quite a bit of "magic" with the conversion to EL-34's.
 
I just spilled watermellon juice, all over my amps and they sparked and caught on Fire..
Now I'm really upset!
I going to see if they're totally ruined.
Im so freaking outraged...

Not good; hopefully you caught them in time, before too much damage.

I run Bogen amps with 8417 tubes and really like them; the 8417 is a great sounding tube, IMHO.

That was exactly my point. Doesn't one usually inquire if something good, or will work with their system before they buy it?

Hey...buy gear as you see fit, but it just struck me as after the fact.


BTW...glad nothing too serious seems to have happened to the amps.

Ideally....... yes they inquire before hand.

OTOH I know I've found myself in situations where I had to make a quick "on the spot" decision about equipment ... unfortunately without the benefit of any prior knowledge in hand. In those situations I'll try and find any information I can to help determine exactly what I have, applicability, etc........ after the fact.

Update on the Quicksilver, mid mono block amplifiers:



These are very interesting amplifiers,they really excel at transparency. Highs and mids expose more music than the Accuphase gear I own and the ASL gear,which I think says alot.
They are musical,and low level details are exposed in the recording,subtle nuances of lesser transients come into focus,and their decay too. The bass has NO mid bass hump at all.

Which is good I think,because whats there,when amplified is really,really clean and defined. Also,I run large bookshelf speakers on heavy sand filled stands,and the low frequencies are handled by a B&W 600 powered sub,so this is a sub/sat system,which in my room,sounds the best.
So far, I like what I'm hearing and I consider these to to be impressive pieces.

BUT,we will see how a longer run with them turns out, and more tube rolling..tweaking too.

I'm using an Eastern Electric Minimax preamp with them and an Arcam Diva 192 CD player,I tried an Accuphase c-200 preamp, and that brought the whole sound down a few notches,no synergy at all. Chock one up for the Minimax.

I'll update more info, as I see fit.

Happy listening!

Power tubes are EH 6CA7 Fat bottles.
I need to upgrade the Sovtek 6922 tubes.
Any suggestions or thoughts? are the Sovteks OK?
Any good new 6922's?
I'm thinking EH,I like their tubes.

Sounds like they have been modded to run those tubes. Here's a shot of one of the ones I had, all stock I believe. I think I have a whole series of pictures, let me know if interested.

My units are stock, with the exception of some dampening material I just stuck to the inside of the units,they're the Mid Mono model,and look different than your picture.
They can run 6L6,El34 and their like,kt88 and others,according to the manual.



They have a LED bias bulb and one pot that you use for both power tubes to bias,seems to work well, too.
Funny thing,when I first got them the other day from the FEDEX man, I put them in the basement and fired them up to see how/if they work, I was using these older Marantz HD series 770 speakers and the minimax pre,along with these new:



(TM) Planet Waves ,cablestation HI-Definition 24AWG 75ohm coax cable



That's what it reads on the Cable.



These cables have neat way to terminate the end with RCA plugs,you simply cut an end clean,then insert the RCA plug into the cut cable,it then touches the wire at the end of the cable,then tighten a screw that then drills/punches a hole to the shied part,thus locking down the cable. works good too.



The bass with these cables and the large Marantz speakers downstairs was thunderous,maybe too much.



ya, the Marantz have 12" woofers and my large book shelve speakers in my main systems are 6 1/4" BUT they still salute with decent power,why did the bass come across so much more down stairs and not up?



The only diff was these new weird cables, I'm going to try them upstairs and see if the result is sim.



I now, have these new cables hooked up to my sub upstairs, as I changed from speaker wires going to the sub, to RCA cables running from the pre to the sub.



I did notice that I have to turn the sub WAY down as more volume goes to the sub than ever before.



If I knew more about the wire and the ratings on it,I would probably have more of a clue.



These PLANET WAVES (TM) wires were given to me where I do work sometimes.

An Audio company (forgot the name) installs custom systems on these 50 million dollar Yachts, and I do the wallcovering work for the shipyard, Delta Marine. They use these wires for the audio and video in the yachts,as all the staterooms have custom home theater systems.



The rca temination were so cool how they came on and of so easy. Plus, you can buy the wire and within a minute have a decent interconnect at any length you want. Take the plugs off and put them on other wires if you want.



So anyway, I'm going to disconnect the sub and put these wires on the pre-out and see if the bass kicks up. Maybe theres something missmatched with these cables and too much bass somehow comes through,I'm going to find out.



The cables are Audioquest Diamondback that are running to the power amp now,and these have always been top preformers. I do know Quicksilver has there own cables that they recommend,that might be worth a try also.

I liked the JAN Sylvania 6922s.

Usually get them from Tube Depot, Tubestore, or Jim McShane.

6922/6DJ8's are not output tubes. I have them on my preamp. I like the Sovtek 6922 bass better than the Bugle Boy's I have.

I have two amps that use EL34's for output. Like the bass of the EL34. KT88's are more detailed, but get down as low to my ears. I have the Gold Lion (KT88) re-issues.
