mcintosh c2600 and ma6600 question


My Mcintosh c2600 has just arrived. Still waiting for my c452 amp. Anxious to try it out. 

1. Is it possible to connect Macintosh c 2600 to my ma6600 integrated while I wait for my amp? 
2. Would there be any sonic benefits? Or introducing a 3rd component would degrade the signal from my source? 
3. If indeed possible, how would I actually do it? Which volume control should I be using? I have an mcd550 as a source. 
4. Are there any dangers in doing this? 
5. I also have a krell kav500 amp, would  this make a good pairing with c2600? Speakers are VA Mozart.

right, well separates should be better so not sure why you would regret that. I've heard others hooking up tube preamp with integrated with good results. 
separates definitely sound better, but I wish I kept the ma6600 for my other system, it was a sweet sounding amp
Mike at Audioclassics suggested I trade in the MA6600 for a C47/MC275 combo saying that would be a big improvement. What do you think?
Depends on your speakers. If you’re going the tube route then why not go fully tube and get a tube preamp as well. I’d go for the new C70 or C2600. A C22 would be a nice match to mc275, buy I think they discontinued the line. Whats does the rest of your system look like?
