Thanks for the quick reply and good ideas.   The digital inputs to the 
1010 (via SP/DIF) are perfectly quiet, the problem is with the analog 
inputs.   I'm (unfortunately) familiar with the distortion arising from 
mismatched sample rates on digital transfers and it is usually 
correlated with the signal.  What I'm getting is broadband noise, 
completely uncorrelated with the signal. 

[I say "unfortunately" because someone tranfered some 44.1 DA88 tapes 
(B-format Ambisonic recording of a concert by *Gidon Kremer and 
Kremerata* *Baltica*) to HD for me as a favor, but he never checked the 
computer interface which was set to 48kHz.]

Thanks...  Aaron <heller@ai.sri.com>
