no volume control

To answer your question,at this time I can only listen to pandora for instance I am only able to use headphones also a three channel rotel has a volume control that I was using for 2 channel playback now only one channel as a problem of blowing fuses and am currently trying to set up with a 2 channel rotel amplifier for stereo analogue source from music fidelity dac again has no volume control which I why I am possibly looking for a good passive preamp now on audiogon a sonic eurphoria for sale and was looking to connect for two channel and best way to set up for optimal 2 channel playback.

Audio output impedance of dac is 50 ohms and input impedance of amplifiier is 33k ohms/1.0 volt.

Thanks for the information as I have been thinking about what direction to take to control the volume output as it seems so many directions to take and the lightspeed attenuator sounds like a good fit. I was looking to replicate sound to be somewhat in the middle between solid state and valve amplifcation. Could you verify this and also how to go about a purchase.
Thanks:
Gary
