Preamp for ARC-Proac System - Is Balanced Best???


Hi Folks! I need some advice bad! I've been auditioning every type of amp out there for my Proac 2.5's, and the ARC VT100 mk2 tube amp keeps coming out on top. As many of said, you can't go too wrong with this amp. I've currently got a Rogue 66 preamp, Cardas neutral ref speaker cables, Harmonic Tech truthlink IC's, and a Cary CD308 CDP. An audio engineer friend was over last night and he looked at the amps schematic and said "Beautiful design, but you should be feeding this in balance mode rather than single ended. This amp was really made for balanced input". Looking at the tube topology, this appears to be so. So my questions are:

1) Should I expect a significant improvement in sound running it in balanced?

2) If so, please offer suggestions about the preamp. Optimally it would have a phono stage and a volume remote, and both single ended and balanced outputs - but I'm willing to compromise as needed. Especially the phono stage. If the price goes down sufficiently without one, I can get an external one.

Thanks. Thanks. Thanks!

Since Rogue offers remote control as an option w/ the 66, why not have them do that? Also, ARC gear is a matter of taste. It does have a slightly thin, threadbare, "white-ish" face to it (at least the many pieces I've heard). I've found this to be true just as Conrad-Johnson has a slightly thick, full, "burnished" sound. I've not heard anything from C-J in 5-6 years, though. The 2.5s have a wonderfully transparent and full bodied sound (sounds contraditory but is true).

I also own 2.5s and have had them for over 5 years - they're not going anywhere. I've always used tube amps which work just fine. However, if ProAc uses primarily one set of amp/pre-amp to design speakers, why is there no real "family sound" to their speakers? I mean, could the 2.5s and the Futures sound any more different? And I couldn't bear to be in a room for more than 5 min with the Tablette Sigs. There certainly is no "ProAc sound" as there is with Spendor, B & W, Revel, etc.
