Oops! In that case why don't you just give it a try? You can judge yourself whether you like it or not. I use to diy my cables, RCA to XLR won't cost too much. And Amazon has some cheap and good cable just for testing:

If you find the sound is acceptable, you may try better cables.

Just read your previous post, that you have tried RCA to XLR and hear some noise. Looks like a special case. In that case i will try to connect the pin 1 and 3 of the XLR to the RCA ground.
No, no...I'm getting NO noise from the RCA to XLR cables. Nothing, nada, ziltch. Just a black background. My point is, I want to keep it that way, running my iDSD micro unbalanced RCA out to my balanced Auditor, via XLR, in. But there's the fear of not being able to drive the amp, and thus my HD800s, with the iDSD, alone. That's why I called Rane, but Rane didn't think their product was for me. Still, I guess you're right: I could try it out just to see how it sounds.
That right, I remember now you mentioning it in your earlier post. I am surprised as well that you are finding the Auditor and the iCAN to be so close sonically. Regarding level matching, I am under the understanding that in ECO mode the RCA outputs deliver 0db and in NORMAL mode it is increased to +9db. Not sure if this takes place in direct mode as well as when preamplifier mode is selected, and may alleviate any level issues when driving a balanced input. Let us know your impressions after the iDSD micro arrives.
The headphone and portable segment of our hobby has been exploding with some really exceptional products over these last several years. This coupled with the plethora of downloadable high resolution music recently, has really made listening to music on the go exciting. I was born 20 years too soon me thinks.
Yeah, the iCAN is sonically similar in quality, even though it doesn't have quite the width and depth of the Auditor. The iCAN is a very clean in-the-ear experience, which gives it a very desirable intimacy. Now, I'm using HD800s, so I'm getting a lot of width and depth there, so I can't attest to what one might feel with other cans. What the Auditor does, however, that no other headphone amp can, is go a bit beyond the 180 degree headphone experience. The vocals breathe a bit more: they float in empty air, brass instruments and cymbals decay clearer and longer...I could go on and on about the Auditor. But, there's a certain charm to the intimacy that I really like with the iCAN. I can't imagine anyone being disappointed. The iCAN is pure, beautiful amp, much larger sounding than its price point. Still, if I had to choose today, I would stick with the Auditor. The reason I'm not, of course, is because I want to hear the iDSD along with the iCAN, the iTube and the iUSB as one package before I make any big decisions. As is, I love the iTube and iUSB...and I love the iCAN, too. I'm just not sure how it will shake out.
I'll be sure to let you know. Thanks for the interest.
