Chain Link Fences So beautiful!!!

I want to buy this!!!

Sweet and smooth mid...., enjoyable clear high.

Thin bass with el34

Spectacular mid-range with remarkable, lifelike reproduction of the human voice. Natural highs. These throw a deep soundstage. Very musical. Smooth.
Well built and built to last. Over 17 years of ownership, I've needed only 2 or 3 modest cost repairs.

Bass not up to the standards of the mids and highs. Bass is flabby.

I've been using these original 8417 mono amps for 17 years. I listen a few hours some weeks, other weeks not at all. I alternate among several sets of 8417 tubes, whcih are not manufctured any more. These amps sound best with the 8417 tubes, which in my experience seem to last forever.

These amps produce lifelike three dimension sound images which suck you into the music. Properly fed with a pristine signal, playing through well set-up speakers, the Quicksilver 8417 monoblocks bring it home, alive. Superlative.

Customer Service

Excellent sound, sturdy build and convenience afforded by separate mono amp units

This model is the original 8417 mono amp now using Sovtek 5881 tubes. Matched with Audio Research SP9 MkII preamp and Sonus Faber Concerto Grand Piano speakers, the monoamps sound great with tight bass, natural mid and crystalline high. With minor modifications, these monoamps may accommodate a variety of tubes namely EL 34, KT 88, 6L6 and 6550. But if you can still find the rare gems of tubes, the 8417s, go get them and your effort will be highly compensated.Kudos to Quicksilver Audio!

Imaging and sound stage.

EL34 is not the best with them.

Somewhat thin with original EL34 with Quad US monitor. Boy, what a difference with 6550C! (Russian Made, requires matching eight of them, costing quite a bit.) They produce beautiful imaging and almost holographic sounds stage. I always used directly from a high-end Sony CD player without preamp.

Sound

Heat, weight

I traded in my adcom on the PS amp. It didn't work very well so I took it in and took a chance. I took home the two monoblocks, along with a pair of castle eden's. I was a very happy camper. WIth my arcam CD player, I was able to hear new sound couldn't distinguish on my old system. Before I had some electrostatic speakers, I'm glad I got rid of them. The warmth with tubes and conventional speakers is amazing. Definately an A+.

Imaging, awesome amp the price

bass a little thin

Well i bought these for a thousand bucks with, el-cheapo el-34's installed....I was not happy as the majic from my system was gone, I have Lamm research mono's also, but don't use them very often as i have allot of little kids running around. Back to the QS...after re-tubing with gold aero kt-88's (about 100.00 each)....wow!! a cheap priced amp that sounds almost as good as the Lamm (12,000 give or take). The only minor complaint is the bass is a little thin...everything else is great!!! My other equipment is as follows:

Altis Reference CD
Audio Research DAC-2
Audio Research LS 15 preamp
QS Mono 60's
Joseph Audio Reference 30 Speakers
Light-Star Silver interconnects and spearker cables

ARC, CJ,

These are excellent amps, especially for the money. Quicksilver uses a very simple circuit, which, as here, usually improves the sound. I liked them from the first time I turned them on. The image well, are very musical, and are sweet without being euphonic. They are only 60 watts, so as one of the reviewers noted, they may not put out a lot of bass and would not work with inefficient speakers. I use monitor speakers and a subwoofer, so for me they are just about perfect. I may never buy another pair of amps. I bought mine from Richard Messer at Renaissance Audio in Florida. His prices are very competitive and he is a good guy to deal with. 941-955-5888

I wrote a poduct review before now i have compared these amps in direct comparison to other amps. I compared it to arc vt 100 and at first I was dissapointed with the quicksilvers .the arc blew it away in the soundstaging department but the vocal on the quicksilver was without reproach.I was still not happy with the quicksilvers because of the lack of information. THAN I tried 6550's watch out. The bass wow it is so tunefull extended not TIGHT BUT REAL.the soundstage opened up but with perfect timber.thhe highs and mids make the ARC sound so steril. I will say it is euphonic more than immidate , not solid state fast but REAl magical .I love it . im now using silver audio syphony 32's they are great reference quality. NOTHING BAD everything is musical and right

Before purchasing these amplifiers I reveiwed Conrad Johnson, Graff, Sonic Frontiers, Bryston, and a few others. These amps presented the music with a timber and clarity that the other amps could not achieve. In comparison, the Conrad Johnson had a golden hue in the sound stage. The Graff was brighter and the Sonic Frontiers was sterile. I still love these amplifiers, but the Quick Silvers were more transparent liquid and presented the vocal and mid range in a first class maner. The Bryston, I love, but was too expensive and the mid range wasn't as magical. Elsewhere on this web site a person states that the Quick Silver compared with the Conrad Johnson had a slow presentation. I have found this is not true. I believe it was the associated equiptment wires, pre amp etc...
