Audio Aero Prima vs. Resolution Audio Opus 21


We currently own the Prima, and have heard the Opus 21, though only for a short audition, and not in our home. Just curious what you might think of the differences? We love the warmth and intimacy of the Prima. It could perhaps dig a little deeper for increased dynamics and resolution. We may spend the $150 to try out the Opus 21, but my concern is having a non-tube player. There is a certain thinness and dryness to most digital that I don't care for. We would spend up to $3K as necessary, but are for a number of reasons apprehensive about the modded players.
We prefer the dimensionality and airy sound of the Prima to the pristine accuracy of say, the Audio Note CDP/DAC's.
Any thoughts and/or recommendations? Stick with what we have? Spring for a $1000 interconnect? OK, not so fast!

A DIN-RCA or XLR connector simply has the single DIN on one side, then splits into two RCAs or XLRs.
The DIN handles both the left and the right channel in one connection. (It has five individual wired connectors.) My cable connection that I had specially built by Audience is actually a "Y" cable. (It has one DIN connector, and two XLR connectors at the other ends.)

Hope that helps!
Just to clarify this, if I ran the standard RCA or XLR on the Opus 21 into a preamp, would I have any issue with the volume control on the unit--since I have not bypassed it with the DIN connector?
I believe the answer is no. You would set the volume on the Opus to max and use your pre for volume control.
