Really like my system now. The only improvement I wish to get is clarity and soundstage. Next step is to get acoustic panels behind the speakers. Also I'm shopping for a DAC.
Have you experimented with and without the PS Audio conditioner in the system? Maybe try the amp plugged directly into the wall outlet and the sources into the conditioner.
I see you use the AZ Satori. Excellent choice, but isn't the Satori a single cable? Are you using the standard jumpers from bass connections to tweeter connections?
You'll need to either contact a Ref 3a dealer or Diane at Divergent Technology as there are quite a few updates, depending on the age of your Dulcet. Prices are variable.
You didn't mention what speaker cables you are using, but since I also have the Dulcet speakers, after much experimentation, I have found that bi-wiring works best on them.
