A few members asked me to post impressions of my new amplifier. I am not the most seasoned reviewer but I will do my best to convey something useful and interesting. I don't have a ton of experience with tube amps. I have always stuck with solid state in my 2 channel (Linn) and headphone rigs until very recently. A couple of years ago I started getting into this headphone hobby and have gone through the following progressions in my chain: HP: HD600, HD58X, Amiron Home, DT1990, Elex, Quad Era-1, LCD2, Arya, Verite, LCD4, Ananda, Aeolus Source/DAC: Meridian Explorer2, SOtM sMS-200, Mac Mini, V850, Qutest, A18, Codex, Bitfrost2, Linn Sekrit Amps: V280, H16, Lyr3, Quicksilver Audio I also had ZMF Pendant for a day but there were issues with it so I could not get a great feel for its capabilities. I had the MacMini/Qutest/V280/LCD4 chain for the longest period of time. If you have any questions about any of the gear above feel free to ask. When I decided to sell my LCD4 and switch to the Aeolus as my primary driver I figured it would be a good time to explore tube amplification. I had heard that tubes had great synergies with the ZMF line. One amp that intrigued me was the Decware Zen Triode OTL. I took advantage of the Black Friday Sale and ordered one. The only hitch is that they have about a 6 month backlog of orders. I figured I would get another tube amp in the meantime and sell one after comparing them. I first picked up a used ZMF Pendant but one tube socket was loose and the amp was noisy so I gave it back. Then I ordered a used HA2SE that got damaged during shipping. I bought a new Lyr3 and thought it was ok but decided to send it back before the trial period expired. Finally, after reading a bunch of positive feedback I decided to order the Quicksilver Audio Headphone Amp. I had considered it earlier but was not crazy about the aesthetics. As more positive comments poured in, I decided that it was good enough looking to try. Quicksilver manufactures these amps in Stockton, CA and have been in business since 1981. Mike Sanders, the owner and founder, personally tests each product to ensure it is performing optimally before it leaves the factory. Quicksilver Audio’s transformers are custom built to his specifications. The amps come with a 3 year parts and labor warranty. The Quicksilver Headphone Amp is a transformer coupled single ended class A triode using (2) 12AX7 and (2) 6BQ5 tubes. It has one single ended input and one single ended output. It retails for $998. I ordered it directly from Mike and received it within one week of ordering it. The amp and tubes were packaged nicely. Aesthetically it looks much better in person than it does in photos. It seems like it is build very well. I have spent a few weeks breaking it in and getting acclimated to how it sounds. Even though the Pendant I tried had some issues, I immediately noticed an energy or feeling that I didn't get from my V280. The V280 is a great, powerful amp but can sometimes be little tame in the treble. It also has images well but gives a somewhat distant presentation. There is a something very organic and live sounding that tube amps seem to be able to impart. I felt the Lyr3 only gave a small taste of that special sauce. This is probably due to the fact that it is a hybrid amp. The Quicksilver immediately impressed me with its sense of space, power, and that magical sound that instruments and voices can make. Power - I typically have the volume pot between 10-11 if it was a clock. The Aeolus are fairly easy to drive but it seems like this amp has enough power for just about anything out there. Additionally, the speed and power of the music is great. I am not missing the outstanding bass response on the V280. Soundstage - The different parts of the band have nice spacing and there is a nice height and width to the soundstage. It definitely has bigger soundstage than the Lyr3 or the V280. The Aeolus is not a soundstage monster so I feel like the Quicksilver is maximizing its abilities. I felt the Arya had an abnormally large soundstage that at first was impressive but ultimately sounded like a parlor trick. It didn't sound realistic. Sound - The Quicksilver/ZMF Aeolus combo is leaps and bounds better in timbre than anything else I have owned. Guitar plucks give goosebumps. Vocals are pure and are not too far or close in the mix. You can feel the weight and textures on the piano and drum strikes. There is some sort of subtle reverb in everything that gives an energy and live feeling to the music that makes it more fun and interesting. Ultimately, it is incredibly balanced and puts a smile on my face when I listen to music. Outlook - I've been so impressed by the Quicksilver that I considered cancelling my Decware order but ultimately decided to let it ride. I will give both a shot when the Decware arrives. Im curious to see how an OTL and a SET amp differ. Let me know if there is anything I didn't cover that you want answered.
