I cannot believe that this whole discussion went by without anybody asking his room size, the kind of music he listens to and how loud? Those were the major considerations for me when I decided I wanted to go back to separates. For example, I have a 28x15x7 room, I like orchestral/organ music and I sometimes like it loud. For me to add tube power amps, we would be talking something along the lines of VTL Wotans (or the like), which are very expensive.
I bought an Audible Illusions 3. Hooked it up to my Pioneer receiver pre in/out circuit, which disconnected everything but the power amp section, and used the Modulus as a control amp. Never looked back. Also a preamp is not really speaker sensitive while a power amp is and must be matched to your speakers. Now I have Quickies V4's and the AI M3A. Just my 2 cents.
