Mytek Manhattan II as preamp


Is anyone using their Manhattan II Dac as a preamp and is it better than a really good preamp with great Dac? I currently have an Ayre K5xeMP preamp to my Mark Levinson amp but have a Mytek Manhattan II on the way and curious if straight Dac to amp will sound as good or better than Dac to pre to amp. Is the Manhattan II analog volume control that good?

I  have a Mytek Manhattan II that I tried as a preamp and it was good but not as good as my Audio Research LS-28 line stage. I use the analog volume control setting and that sounds marginally better than the digital volume control setting. Try it and see what you think.
I must say, the Mytek is outstanding performer as a Dac through my Ayre preamp but the sound is dull, not as airy and soundstage much smaller using it as a preamp. I guess I didn’t realize how good and big a difference my Ayre K-5exMP is! Dac with good separate preamp is way to go.
