Hi
I am running an M3 factory 2006, with Bendix tubes in, superb sound. It got a lot more bass slam and depth from the normal tubes. I have a CD1, DAC 1.1, and a pair of conquest with TJ Solid mesh tubes and sylvania 1957 6SN7WGTAs.
Rest in the amps are philips. Tube in the DAC is a Mullard cryo.
Speakers I use are Zingali overture 2s 2006, and a REL sub, which integrates real nice.
On your system, and M3 would compliment the Conquest really well, a big step up. I would go for new M3 rather than second hand M5/6. The current M3 is amazing build and parts quality, and the higher models a lot more money for smaller jumps in quality. Let me know how it goes.
