pre-amp with home theatre pass through

I believe it has what you want.

Sell your old one and pick up the RDL1 (used)

Sonic Frontiers Line 1,2 and 3 also the Gamut preamp

I have a SF Line 1 with a similar setup. The HT passthrough is great. If this is your main TV which is on most of the time, keep in mind that any tube based pre-amp is going to get alot of hours logged on the tubes even while in HT passthrough mode, at least that's the case with the SF.

the mcintosh c2200 tube pre has a ht pass thru,i couldnt tell ya how it works as ive never used this feature on mine but i know it has it.
