Transport with volume control?

Thanks all for the helpful information. My understanding is that the course VC on the Goldmund is more of a level match than useful line attenuation hence the need to have some form oof extenal atenuation.
I will pursue some of the routes suggested.

The McCormack SST-1 has digital volume control (this is a fact-I own one). However, when lowering the volume this way, you would essentially be throwing away resolution. My one word suggestion: DON'T!

I have an older Goldmund VSR alize 3 DAC and when I hook a cheap DVD player with volume control to the DAC I can attenuate the volume. Although the quality is not as good as with a proper transport. SO, DVD digital outputs are indeed controlled with the volume on remote; at least with my Goldmund DAC.
