Which AV processors have an analog pass-thru?

Sunfire's Theater Grand 2 does, and it is, surprisingly good for the price. More tube-like and musical than most <$2k silicone pre-amps I've heard.

I just checked the Casanova manual.

Analog inputs are routed directly to the tape-out i.e. bypasses all else in the pre-processor.

Digital inputs derive the benefit of the Theta DACs and then the output is passed to the tape-outs untouched by any other processing.

You can pick one up "previously owned" for around $5k US

The Primare P30 retailing at $4k is an excellent sounding pre/pro that I've been using in my 2-channel system for the last year. Has a 100% analog by-pass mode. A very simple design with no tone controls. In addition to the rca outs, it has xlr outs for the 2 main channels. It appears that the P30 was designed with a music first priority.

I've had a burned-in Ayre k3-x preamp in my home over one weekend performing side-by-side sonic comparisons. The Ayre was a tad sweeter and more musical but the Primare was much more transparent and detailed, as well as more appropriate midrange bloom when compared to a recessed midrange in the Ayre. IMO.

the sony es dolby digital processor from the mid 90's has an analogue pass through. But, I use a DB Audio passive switch box (five rca ins, one out); the parasond psp1500 AV preamp and the McIntosh C22 preamps to into the DB Audio box. The output goes to the Audio Note P2SE amp that drives the front speakers.

NOTE that this little switch box can also be used as a cheap passive preamp IF you have an amplifier that has a gain control. I have done this and it works great.
