cj Premier 11 capacitor upgrade

Looking at conrad johnson's website, I see that they're offering their C1 capacitor upgrade to several vintage amps/preamps including the Premier 11. These are their proprietary Teflon capacitors. I always thought that the Premier 11 was a very musical little amp and would welcome anyone who has either had or heard this upgrade to comment.

I just saw it on their website also and plan to get the upgrade done to my CJ Premier 8A monoblocs so as soon as I do I will let you know how they sound.

I have recently had my prem 8a's upgraded with cj's teflon caps.

added transparency, a little quieter and overall a more sophisticated musical presentation

highly recommended.

I just upgraded the caps on my Premier 12's. Outstanding. I have 88.5db speakers and they always sounded a bit sluggish with the P12's. Not any more. Now more attack and overall better control and detail. Lifted another veil or two. Everything sounds better and its only been a few days. Very close now to the LP140M's, except the 140's have a little more bass. We'll see if there's more bass with break in - plenty now anyway.

Hi Ddrave44,
Just to be clear, you had the Teflon cap upgrade offered by conrad johnson? They are supposed to require a lengthy break-in and sound terrible until they do.
