Who is using their DAC as a preamp?

how bad a deal can it be when one has two options for volume control and signal development?

it has to be considered a plus.

... a backup.

... another perspective.

... a change of pace, if nothing else.

although its not a deal breaker, I look for that option in what ever DAC I believe I would like to buy next.

I wonder what quality the Mytek dacs have? I have read that the PS Audio pays special attention to their volume controls. 

I've been using the Oppo 205 as a preamp as well, straight to the mcintosh mc275, but am considering putting a ps audio stellar gain cell in between to see if there's an improvement.

For late night listening, I currently have a Schiit EQ (Loki) in the effects/tape loop connection of the Rogue. I just boost the lower frequencies a little...basically I use it as a loudness switch. Since the EQ has "true" bypass, I can just use it in line between dac and amp if I decide to ditch preamp.

An excellent choice for late night low volume listening, and the Schiit Loki at $149 is a bargain, does all what you said and more,   https://www.schiit.com/products/loki   just put it between any of these configurations: 
1: Between source and poweramp (if you have source volume control)
2: Between source and preamp
3: Between your preamp and poweramp.
4: Or in the tape loop on an integrated amp.

There is a poster on another thread that uses a 1/3rd octave 31 band eq, as his passive device ( it has dual channel gain controls ). He compared it, flat, to 5 K preamps, and says it is superior to his ears. I have the same eq ( and I tried it via his recommendation ), but did not feel it came close to my Luminous unit in sq. However, it bettered some of my cheapie preamps ( RGR, Hitachi, AGI, Citation, GAS, SAE, Dynaco ). I sold my 2 megabuck preamps, which were both bettered by my Luminous unit.
