Preamp to Run Revel F52s & C52s

I have the F32's and C32 and run mine with a McIntosh MX135 in theatre mode and when I am listening to 2 channel I am using an Audio Research LS26. I get a very good detailed sound out of both. I did gain a good step forward by adding the seperate 2 channel preamp and using it's unity gain for pass thru on surround. You may want to keep the Onkyo in place and just buy a 2 channel pre amp with unity gain. Some manufactures call it cinema pass thru, theater pass thru,processsor pass thru, etc. You will gain a much better step forward by adding the processor pass thru. It basically allows you to have 2 systems in one. You didn't mention a budget?

something anyone should experience is the axiom piece for a simple 2 channel that will blow you away! Great music doesnt have to break the bank Good Luck

Thanks Theo, I have to admit complete ignorance to the ever changing electronics world. How does the theater by-passs work? Wiring etc.... Would like to keep budget around $1500
