I've strayed....

So after looking for some time at what tube gear to purchase

and coming really close to a PrimaLuna and a Rogue Cronus Magnum integrated amp, I ended up with a McIntosh C-28 pre-amp and an MC-2105 Amp.

Partly because my current speakers are (from what I've read here) not really tube friendly, partly because I can tube either piece in the future partly because I've read great things about this combination and partly because I've always wanted McIntosh gear.

With that out of the way, what else do I need to know or should I just have at it, set up the gear, start listening and begin tweaking or... is there a methodology for optimizing sound like start with flat tone controls, position speakers, once speakers provide you with xyz, adjust the bass until... etc.

As always, thanks in advance.
