Need suggestion on tube amplifier with XLR inputs

It sounds like you might be in over your head. Wouldn't a simpler system result in a better sound? That has been my experience.

With all due respect, this sounds like a horribly overly complex setup, which would be difficult to wrap your arms around.

I recommend stepping back to see the forest from the trees. For starters, are you using this rig mostly for movies in surround, multichannel music only, or 2 channel music? IME, most 5.1,7.1 etc. has most music from front mains, and the center channel is mainly spoken dialogue. Any rig that is bi or tri-amped is going to rely on expert knowledge of crossovers etc. to get any kind of balance. You mention everything except what your speakers are. That would help.
Can we translate your question to something akin to,

"I have X speakers in a HT setup w/JL subs, driven by Krells. What amp would make sense for the other 5 channels?" Cheers,
Spencer

If you have 3 midrange drivers in each channel I would put them in series since you have an electronic crossover- that will make them easier for a tube amp to drive.

However Jim and Spencer are both making good points- getting the system to blend and work together as a unit is likely your biggest challenge.

I don't feel like I am in over my head here. I am just trying to put together a system that utilizes the advantages of the different amplifier technologies. I don't have $30,000.00 to spend on a tube amp that can push my subs so I have to use SS for the low frequencies. As for the mids and highs, I would like to use tubes as they produce a warmer better quality sound (according to most reviews) and since my mids and tweeters are more efficient than my subs I think that I can us a less powerful tube amp (mainly one that I can actually afford) to drive these speakers. The reason for wanting them on their own isolated channels is so that I have more granularity in tuning each of the speakers so they sound right in the room that I have them. I do agree that a simpler system more often then not sounds better then one of extreme complexity but I would like to try to put one together that does sound good as I have a severe case of audiophilia and thoroughly enjoy messing with this type of stuff for hours on end. I am actually so into it that I have built all of my speaker enclosures using various software to tune each of the different drivers. I am not sure of how or if I even can but I would like to post a picture of my sub woofer box on here and I think once you see that you will agree that I am not in over my head with this... :-) So I guess the question remains, what would be a good tube amp for each of my speakers, I have 2 Morel's 531's which are rated at SPL: 86 dB 1W/1m and I have one tweeter PylePro witch is rated at SPL: 109 dB 1W/1m. So obviously the amp for the tweeter does not need to be very powerful at all but the one for the mids will need to be somewhat powerful. Since I would like to use two different amps to drive these what would you guys recommend for each of the stated speakers? Thanks again for any and all input!

Also let me know how to post pics if that is even possible as I would like to show you all my sub enclosure....

What is the cutoff frequency of the sub? That will make a big difference as to how much power the mids will need. Can you rearrange the drivers in that box so that they are in series?
