How are you implementing surround sound in your home theater while including tubes. Even if just in the front end. Are there five channel tube preamps, affordable ones? Am I trying to do too much with incorporating my hifi into my HT?
Follow Ups:
...a c-j MET1 6-channel tubed preamp and 2 Music Reference EM7-2.5 SET poweramps. The main speakers, open-baffle line-arrays...
...are rather sensitive at 97dB, so the 2.5-Watts-times-4 are plenty for 4 sections of my triamped systems.
The bass sections of all 3 front-channel speakers are driven by a 7-channel Outlaw poweramp.
The MET1 is hardly 'affordable', but you might find a Copland CVA 306... http://www.divertech.com/coplandcva306.html ...used. The EM7-2.5 poweramps are bargains at about $750 each, but not many HT systems can sound good with 5 Watts per speaker.
All digital-to-analog conversion is done within my 2 disc players; I use the 6-channel-analog outputs.
As is visible from the white label, I've converted one of the tape-outs to an additional center-channel output, since that system too is biamped and I didn't want to use an RCA-cable splitter.

I only have one room for both music and HT. My approach is to use the VAC integrated amp for my front L/R speakers and a 5 channel YBA amp that has tube-like characteristics for the center, side and rear speakers in a 7.1 setup. I use a YBA preamp that will control the multichannel amp as well as the VAC for HT applications. The VAC has an HT setting the decouples the internal preamp from the power section. It works well.

The only MC tubed pre's I can vaguely recall cost $10K or so (Conrad-Johnson?). I might get a local manufacturer to custom build one for me funds permitting. I also want five (5) tubed monoblocks but that just might be asking for trouble with inefficient speakers, lossless audio, and dynamic impacts of HT.
Oscar, as i stated below just use two ordinary preamps. And I am going to use cool running T amps on the rear.
If I ever do this, it'll probably be in the form of power amps, because I already own 4 channels worth of single-ended amplifier, with another 2 channels under construction. But although these amps are cool-running for tube amps, 5 channel's worth of them would still likely make my room uncomfortably warm in the summer months.
Most of the speakers that I'm interested in should be fine with SETs--fairly sensitive, easy impedance curves, etc.
I am thinking I will use SET on the front and make use of the T amp I have on the rear channel.
I am also going to follow Doc B's advise and use two Foreplay preamps. Although I won't have remote volume control, it will be affordable and I need the exercise that will come from getting up and down.
When I just want to listen to the FM tuner, I will just turn on the preamp for the front, and it will have the tuner inputs.
I guess that will work, but I don't know about Dolby or any of this fancy 21st century stuff.
I think I am giving up on integrating my PC with home theater for watching tv.
and High res format players will have 6 channel output which will output a DD signal.
