I use a retired receiver as a headphone amp. Its source is the analog out from my CD player. The CD player raw coax output goes to a external DAC then to the main system via my CJ PV14L preamp. I believe that I can connect the receiver to the DAC using the CJ's EPL (external processor loop) circuitry but the CJ manual language is minimal and isn't easily assimilated.If I understand the manual correctly, with “CD” (DAC) input selected, when I select “Source” out, the signal will go to the power amp as usual but if I select “EPL” out, the signal will loop to the receiver as if the DAC were directly connected to it. Or should I use the "Theater" out, which according to the manual "sets the level at unity gain for both channels"? I guess I'm not clear on "line stage", "line level", or "unity gain". I'd love to actually have the PV14L drive the receiver and headphones but I don't think that's doable with the current equipment. My concern is overdriving the Parasound's preamp section and damaging one or both preamps.
Secondary question: Can I safely connect the receiver’s tuner to the the PV14L via its “Tape Out” to the preamp's “Tuner” input?

EPL loop is basically a tape loop but designed so when using the theater out disables the preamp gain for use with a Dolby processor ( use the processor to set overall gain to keep all channels in calibration). Use main gain to set front two channels only.
Since you're using pre feed to a receiver, you can use either out put. My get best sound feeding main out to receiver amp input
C-J says that any source signal will be present at the EPL OUT jack. So, if I understand what you're saying, I can choose either EPL OUT or Theater OUT to feed the DAC signal to the receiver's CD IN. EPL OUT will have gain controlled by the C-J volume controls; for Theater OUT (unity gain) the gain is controlled by the receiver's volume control. Right?
I'm not clear on what you mean by "get best sound feeding main out to receiver amp input." The C-J "Main" OUTs will remain connected to the amp in my main system. The receiver I'm using for a headphone amp is an old Parasound DR65. It's only inputs are the line sources (CD, Tape 1 or 2, plus phono) so any input from the C-J will feed into the receiver's preamp section. I don't want fry anything.
No EPL out is fixed at input gain, in other words volume in is volume out. You are bypassing vc on cj. Think of it as tape out. EPL in completed this dort of tape loop.
Use unity gain out for your recvr using its vc's.

Yes to the secondary question. Receiver's tape out to any line input of the CJ. Not sure on question #1.
Thanks.
