This is what I'm affraid of because I like my Marantz a lot but I really want a warmer sound. I use the tuner on the Marantz so I figured using the pre-outs to a tube power amp might do the trick. I also don't think I can do power amp and pre amp in one shot right now, so I guess I'll see how it goes. I was looking hard at the Latino St70 or ST120, little more in my price range than the something like a EVO 400 Primaluna.
I do know how to solder a bit so building a kit might be an option for me.
Awesome, there are so many amps out there to check out that I don't know where to settle. McIntosh looks great but they are pretty expensive, so are the Primalunas.
