Monarchy DIP/Unsampler boxes effective tweak?

No, but I have put a ferrite ring on the existing power cord, just in case the DIP is a source of noise on the power supply to my other components.
I'm not sure that I noticed a jump in performance, but I tend to assume that digital components have the possibility of injecting some level of noise back into the power supply so a ferrite on the cord seems like a wise precaution.

Hello Chad,I have a Mark2 ,I used a Moray James PC on and got a worthwhile across the board improvement,def. better than the stock PC!

I've tried both the standard DIP and the DIP upsampler and prefer the standard DIP. I was using a JVC DVD player as a source and an upsampling MSB Link III as a DAC. For this set-up, they were both worthwhile tweaks but the standard DIP was better.
