I had a DIP between my Classe DAC-1 and Classe CDT-1. I used Illuminations D-60 in and Orchid out. The combo worked quite well until I installed a P300. Then the DAC and CDT sounded better without the DIP. I believe that the conditioned power helped to lower the jitter further than the DIP could. Further improvements came after swapping out the Orchid for AT&T ST glass. Just my experience, your's will vary.
How to cable my DIP?
I've just added a new DAC (Classe')which I run balanced via AZ cables to my BAT VK3i. It has added a new dimension to my system while keeping the WAF of the CAL-10 which is now being used as a multi-disc transport. I have picked up a Monarchy DIP which only accepts a co-ax or toslink input. I will run the DIP to the Classe' via an AZ digital aes/ebu cable. My question is, with the digital magic going on in the DIP, does it matter what kind of co-ax I use, assumming that it would at least be a true 75 ohm (probably a Canare) cable?
