Calling all First Sound Preamp Owners

You got it Kevin! I'm running the Audience PowerChord on my FS, and I think it's great. I haven't heard the other ones though, so I can't offer a comparison. Another PC that gets positive reviews is Virtual Dynamics' Nite cable.

As for tubes, I know Emmanuel likes the Siemens 7308 as shown above, but I personaly didn't care for them as much as some folks here. I really prefer the Amperex USN-CEP 7308s or the Philips E188CC SQs instead.

try the a-frame pq amperex. It offers a very balanced view of the recorded acoustic.

Audiofankj -- You mention that the biggest improvement was with the tube rolling to NOS Siemens 7308 gold pin tubes. Where did you purchase them as I hear they're scarce?

Thanks,
Kevin

I purchased my pair from Kevin at Upscale Audio, which I believe is an A'Gon dealer on here as well. Their website is www.upscaleaudio.com

Good luck.

Kevinzoe, I've tried Siemens 7308, Amperex 7308, Amperex 6922 PQ
and Philips 6922 SQ. All are excellent tubes. In my opinion, the
Siemens are the best, but you would also be very happy (I think) with
Amperex 6922 PQ White Label made in USA. They are very close to the
Siemens sonically, and they are easier to find. Don't let the scarcity of
Siemens 7308 tubes lead you into a sense that only they will satisfy your
quest for better tubes for your First Sound. Do a search for
"Amperex" on Audiogon, and you'll probably come up with
some for sale. If not, they appear from time to time with relative
frequency.

Also, you might read "Joe's Tube Lore" if you haven't already.
It's a good primer on 6922 and 7308 tubes. Here's the link:
