Experience with Monarchy Audio DIP

Just wonder if anyone has experience/owned either a Monarchy DIP (Digital Interface Processor) Classic or Combo and got significant improvement in the sound. First I thought adding another box between the source and a DAC would be a none-sense but wow, I was wrong. For my curiosity, I borrowed a DIP Classic from a friend and put it between my HK CD player/Apple TV and my tube Cal S`igma tube DAC. I immediately heard a noticeable improvement. Things seemed livelier. More seriously listening revealed that the bass was tighter and the highs had a bit more air. Imaging was more precise, clearer notes on instruments and vocal was more solid.

Hope that other people hear the same things I heard. I want to order one but still not sure if I should go for the DIP Classic or Combo. The Combo also converts up to 96Khz but I dont know if I really need that and the DIP Classic is on sale for $240. Can any DIP Combo owners share their thoughts?
