What preamp & power amp to buy?

Thanks for your response guys, I will try and audtion the Rowland 625 and also talk with Andy Payor from Rockport regarding what works and what doesn't.

A quick search of Virtual Systems on Agon showed systems where Rockport speakers were paired with Boulder (mentioned above) and also Gryphon monoblocks. Might also be worth auditioning or asking Rockport about these.

Good luck, your "problem" is arguably one of the better ones to face!

If cost is no object then IMHO I would flying out to all the Rockport dealers to see/hear what they are paired with and assess the performance.
If you can afford a 100K worth of electronics I am not sure what you are going to glean from this forum - I doubt that many people own equipment in that stratosphere.

Please do not take this response in a bad way - but if you do not have a budget relatively speaking... a trip to a few dealers makes more sense to me then advice here.

Go to Lamm Industries. They have the best sounding gear.

I second the recommendation for the LAMM products.
