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.

OK, now I get it. so my recommendation would be USB out to DAC. DAC output to passive pre. since it does not appear that you need a source selector, I would recommend the Lightspeed Attenuator which you can buy from member Georgelofi. do a search to read the long thread about the LSA which is considered to be one of the true high end bargains out there. I've had one in my system while by main pre was out being upgraded. Cost difference about 20X, sound quality difference not all that much.

If you can tell me what the output impedance of the MF dac is, and also what the input impedance of the Rotel is, I can tell you if the Lightspeed Attenuator is suitable for your system.

Cheers George

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

Hi Sugar1. The 50 ohms drivability from your MF dac will easily drive the combined load the Lightspeed Attenuator and Rotel amp and the 1v sensitivity is also a great figure to have
