Does anyone swap?

Hi everyone,
I was thinking that I would like to hear some other DAC's in my system, but I don't want to buy one in order to accomplish this goal. So I thought that maybe I would offer to swap my Birdland Odeon-Ag with another 'goner for 30 days or so. If you've got a DAC (preferably with volume control) and you'd like to try the Odeon-Ag in your system, let's swap! I think the Birdland is absolutely fabulous, but I'd like to hear some others.

Chicago area 'goners are a plus, but I'll mail it if the swap is a good one.

I don't know that this kind of thing goes on very often. Any thoughts on the idea itself are also welcome.

Cheers.

Tom
