Michael,

Thanks for your reply. Actually, I was planning to E-mail you directly last night until I saw that you do not accept unsolicited E-mail.

I understand exactly what you are saying and what Kotches meant in his post. However, my question is, would not connecting the pre-out of the receiver to the Aux in of the A3CR preamp mean boosting the signal twice(once by the receiver's preamp stage and again by the A3CR pre)? The pre-out on the receiver has an output level of 1 V (Impedance 470 ohms), whereas the Input sensitivity of the A3CR pre-amp is around 200 mV (Impedance 50 kohms). If the only implication of this approach is that you have to reduce the volume level to compensate for the double boosting then it is not a problem at all.

The preamp dealer suggested connecting the receiver's tape out connections to the preamp's Aux in connection. This seems fine because the tape-out has an output voltage of 200 mV, equivalent to the preamp's output level of 200 mV. However, one concern I have with this tape-out approach is that all the signal from the receiver may be channeled through the tape-out connection and that I may not get the surround effects.

I appreciate the posts you made. At least I know that I can use the DTR-6 with my stereo system. For a few days I was afraid that I would have to sell the unit and buy a better one that has an amp-in input (such as Onkyo Integra DTR-7 or better). I would really appreciate a clarification of this pre-out versus tape-out issue.

Thanks.
