Tube Pre to mate with Parasound JC-1s & Maggies?

Just saw an ARC LS25 on AGon now...with some very nice tubes i see. i own Amperex 7308 white labels. nice. good luck

A newer model Rogue99 magnum will be just the ticket ,and they even have an optional phone board that just plugs in and comes with a seperate power supply which is a big plus..
The 6sn7 Vaccuum tube is one of the best ever made and has superb sonic characteristics much more realism and life than the much smaller 12ax7,or 12au7.I have also had the so called super tube all it is is a much more linear 6922
or 6dj8. if you want total nuetrality it is good if you want a little body and a more 3 dimentional sound than the 6sn7 tube is the ticket.

Audible Illusions Modulus 3A. Can be had here for 1000-1400.00.

I think you need a very lively preamp to go with the JC-1's. My experience is that the Audible Illusions isn't all that lively. Rogure might do. An older CAT. How about an EAR? Not quite as lively, but very musical and far above the AI, you might find a Hovland HP-100. Let us know what you end up with.

EE minimax is quite lively.
