I think you are right on about getting little help by auditioning a DAC or any other gear in the context of a totally different system at a dealer. If you were using a dealer they should just let you take it home anyway isn't that what a good dealer does anyway.
I like your system a lot. The Blue herons are awesome and love the hovland preamp. What is your current source components? I personally would buy one of these DACs that are being recommended here used and see what you think. I would personally recommend the MHDT paradisea or Havana as a great starting point.
