I have an Audible Illusions 2c tube preamp that recently had ceramic tube sockets put in by Art Ferris at AI. It has kept me happy for 20 years. Occasionally you'll see one pop up on Agon for about 400-500. With a good solid state amp like you have, you'll love the sound. The tube socket upgrade made the preamp way more quiet and eliminated tube microphonics (subtle ringing). My preamp sounds significantly better than when I bought it in 1991. I've upgraded my entire system using Agon in the past 2 years with the exception of the preamp. It also has a very good phono section in it. If I were to upgrade mine, I would probably only consider 2 companies--AI and Modwright. It would take about 2000.00 used to make a noticable improvement. I just don't feel the need.
how to pick a preamp?
Due to a personal ephanney (was going to build a 4 ch. Stereo) got the 1st amp a parasound hca 1200 set it up with a B&k ref.30 for its capability of 4 ch stereo. After listening to just 2 ch stereo (as I was told, (if not scolded) for a few months I understand now!!! It can't be improved by more chs. So new direction-- going to keep it 2 ch.but now concidering a diff. Pre as I love the sound I get from the hca 1200. How do I evaluate a good pre vs a great pre. Funds are limited to about 3 to 5 hundred for a used quality vintage pre. I want accruate, quiet warm stereo sound. Any help would be appreated!thanks to all those prevouis members who tried to educate me earlyer. It was not in vane just had to here it myself and you were right!!!
