Dragonfly 1.2 Feedback/Impressions ?

I'm beginning to play with computer based audio, looking for some feedback from others that might be using my DAC. I'm running a Macbook Pro with Audirvana, the Audioquest Dragonfly 1.2, Infinity Creshendo 3006 speakers, powered by a Fisher X100B amp.

I really like the Dragonfly with headphone listening. It's open, warm, and detailed. I tried running it into my Citation I/MC275/Bozak B302 main system and didn't seem too terribly impressed - my Rotel 1072 seemed much richer.

I am using 24/96 files from HD Tracks and ripped CD's. The quality of the recording seems to be much more important than the same resolution and sample rate so far. I have some 16 bit tracks that sound wonderful and frankly some of the 24/96 stuff from HD Tracks just doesn't measure up.

Is anyone running the Dragonfly in a mid sized or full sized system with impressive results, or is it just too much to ask for this device? 3.5mm to RCA cable recommendations? Other tips appreciated - I'm totally new to computer audio. I travel for work, and am completely sold on it's benefits and performance in that application. If I have to spend more $$$ I'm seriously considering the Schiit Bifrost Uber Analog unit based on everything I've read.
