Preamp to use with Rowland mono amps

I am using both a Klyne (SS) and a First Sound (tube) with my 201s. The jury is still out. I suspect you could use just about anything you like.

Rowland will also have a new preamp pretty soon: Concerto. Lower priced than the Synergy, apparently designed as a companion to the ICEpower 201 and 501 amps. Phono options. $3900, I think. Also available as an integrated amp in combination with two channels of 201 amplification.

I have a Jeff Rowland amplifier(Model 10) in my system and have used a number of ss (including Synergy 11i) and tube preamps over the years. The best sounding preamp I have found for my system is the Conrad Johnson 16LS Series 11.

I used to run a Rowland Synergy 2i with 12 monos, it's one of the better preamplifiers out there, it's lush, clean, and fast. I have since replaced the Synergy with a Ayre K1x, everything seems to open up, sound expanded in all directions...more 3D soundstage. If you like the Synergy, you hould definitly audition the Ayre, you won't regret.

I have used to great effect, an Audio Research REF2 MK1 into my Rowland model 9T monos

i had great luck with my rowland consonance and model 6's
