Weird Setup - Will it Work?


I am helping a friend buy a new stereo, and she wants it to control speakers in two room (living room and kitchen). She also wants a tuner. I am steering her toward a Portal Panache amp, and originally thought she could use her old NAD receiver for the tuner. Now that I know she wants two sets of speakers, and that both speakers should be able to play the tuner and the CD player, I thought of this setup, but am wondering whether it would be potentially dangerous as it could set up a feedback loop between amplifiers. Here it is:

- Tape out from NAD receiver goes to Panache input #1
- CDP goes to Panache input #2
- Tape out from Panache goes to NAD input #1

When she wants to play the tuner, she simply switches her NAD to FM and her Panache to input #1. When she wants to play a CD she simply switches her Panache to input #2 and her NAD to input #1. The potential problem arises if she has the both the Panache and the NAD switched to input #1 at the same time. In this case, the Panache is "hearing" and outputting the NAD, and the NAD is "hearing" and outputtng the Panache. That makes a loop. Are preamplifiers any more immune to the potential feedback problem that could ensue?

The way around this would be to buy a CDP with two outputs, such as a Jolida. But I'm trying to save her money and get a less expensive CDP (e.g. Cambridge Audio 500SE, which I think is quite good sounding in its price range). So, I'd like to stick with the first approach. OR - any other ideas? If not, I'll be asking for recommended integrateds or receivers with two switchable speaker outputs!

Thanks.

Easy to see what you are trying to do. There are a number of ways. Kill that feedback idea. She has to be at the tunor and other unit to control station, and volume. So put a speaker selector there and you go NAD tape out to P#1 and Cd in p#2. Vol and speaker selector on the P unit.
Elevick's is the best solution. Do the 'complex' set up of the receiver for her, show her how to use it and let it go. Most people are not audiophiles or tinkerers. Give her the convenience she wants and she will be happy!
I spoke to Joe Abrams (Portal) and he confirmed that the Panache can easily drive 2 sets of speakers with the way it handles low impedence. She could put a Radio shack volume control in line to the kitchen speakers, keep it out of the Living Room speakers. That's reasonably flexible I'd say! Thanks all.
