Our systems have similar pieces. I have the Tyler Taylo 7U. My source is the Cary 308t. My pre is the Shrimp.
I had been driving the 7u with a McCormack DNA-125 with what I though were fine results. I recently switched out the McCormack for a Tim Rawson Aleph 5+ and must say, I prefer the Rawson to the McCormack.
The DNA is a more forward presentation with defintiely more flesh on the bones. With the volume on the Manley at only 11 o'clock, it was ear splitting while still holding together nicely. With the Rawson, however, the soundstage is more seamless and coherent with a bit more detail and less congestion. For rock, the DNA is probably the way to go, for jazz, opera, & classical, I prefer the Rawson.
The Shrimp is a great piece and works well w/ SS or tubes. The Tylers are more efficient than their specs may indicate (86db, 4 ohm). My next move is to try a tube amp, maybe a CJ MV60 or ARC VS 55.
Keep us updated on your results.
