Elizabeth,
(aka the "alien"-->your answer to the abduction thread was hilarious, btw!)
Thanks, I won't. I had wanted to somehow put the Dodson DAC in the chain. Right now, the only jack is on the output of the Onkyo, which is ok, but would have to be considered the system's weakest link. I own a Ramsey SHA-1 (or something like that) headphone amp, which I'd been running from the line level output on my Sony Discman. It USED to sound great to me, but with the acquisition of the Summits and the Dodson, it now sounds,...um.... less satisfactory, even with Sennheiser HD-600's. I own no suitable cassette deck either.
So NOW what do I do? I'm spoiled and want the same phenomenal sound, or at least close, from the headphones, but I'm also a cheapskate, and my wife will probably kill me (or at least give me a stern talking to) if I suggest sinking a few more grand into more "stuff."
