Which AV processors have an analog pass-thru?


Which AV processors have an analogue pass-thru? I want to use a seperate tube pre-amp when listening to two channel and need a AV processor that has a analogue pass-thru. I believe Simaudio has one but are there others?

I am confused why you would need this... why wouldn't you just plug the source into the preamp directly? I cannot think of an analog source that you would want to share between an AV processor and a preamp.
There are several analogue sources that you may want to keep that way. For instance, a tuner, TT, cassette, etc... would all provide you with analogue signals. No need to convert them to digital and then back to analogue. Hence a pass through would be something to look for. However, RCLad may be better suited to either looking for a two channel tube preamp that has a processor loop or plugging those sources directly into a preamp / processor that has analogue inputs. That is, if he can find a processor that suits his needs and offers good two channel sound. Sean

I added a tubed preamp to my HT system for music and did just what Slartibartfast suggested. My Sony C333 SACD player is connected directly to the tubed preamp. The main L/R channels from the A/V processor, a B&K Components Reference 10, are also connected to the tubed preamp. You can also accomplish this goal by connecting the tape monitor out to the tubed preamp; my understanding is that the signal passes through the A/V preamp virtually untouched.

The Anthem Pre 1L and 2L are both tubed preamps with a processor loop - kinda the opposite of what you asked but they were built with your situation in mind.
I guess my viewpoint is that if you are concerned about audio quality, you shouldn't be wiring your system this way. You should run the 2-channel output of your processor into an input on your preamp or a processor loop if available before running your preamp into an analog pass through input on your processor. This is a bigger pain to deal with because you need to set the position on your volume control for movies but my perspective is that the noticable loss from movies would be much less than from music using an analog passthrough.

The Krell HTS2 has an analog passthrough.
