Happy New Year first
I am in the process of home improvement and will be adding a tube amp and pre along with tube friendly front speakers.  As part of the project I would like to take my present front speakers and move them upstairs to my bedroom and run them off the "B" speaker outputs on my Sony STR DA3000ES receiver. (the Sony's preouts on the front left and front right would become an input to the new preamp.)
The route of the speaker wire includes the attic and the temperature extremes that happen in an attic.  Also , allowing for the up and down inside walls etc., the length appears to be about 50'.  Is that too much distance for signal attenuation, RFI,EMI whatever ?
Has anyone had any experience doing something similar and can you offer some wisdom and experience?  Also a reasonable costing speaker cable (given the great length and issues) would be appreciated.

I'm not sure what the relationship of the tube gear to the B channel of the Sony is but.... I'll give input on just the Receiver and B speaker part.

I used Monster's in-wall type speaker cable for about a 40' pair of in-wall speakers that were powered from a Sony receiver.  The in-wall's sounded great and there were no problems.  If you're in an area highly susceptible to RFI, be sure all your connections are very tight.

Kimber also makes in-wall type cable if you want to go with something more expensive.  Home Depot and Parts Express have in-wall wires that should do the job with aplomb.

Good luck.

Carlman:
40' in wall speakers must be capable of decent bass
Just kidding, thanks for the rec, and you were right, there is only a vague relationship between the addition of new equipment and putting the speakers 50' away from the receiver.

But
During the holidays I spent some time with an AES Superamp and AE3 Pre driving Vandy 1C's and was so impressed that I just have to have them.  Digital amps are cost effective but the AES stuff is the real poop.
