Sounds like a poorly designed piece of kit for the price.

As mine was burning in, I thought there was very little burn-in change compared to some DACs I've had. After about 300 hours I noticed that it was more relaxed and that it had changed character. But again it wasn't as big a change as with other equipment.
I've also found it sounds better through my external tubed preamp than using the built in digital attenuation. (!?)
Also found its susceptible to incoming noise on the USB and spdif inputs (getting rid of electrical noise before it arrives improves it a lot). its also susceptible to noisy power (likes shielded power cords and up front passive filtration).
Have you experienced the lack of noise for reference to notice? Power isolation transformers are good for digital gear. Removing the RF and other frequencies inducted into power lines lets the DAC power supply do it's job better. Usually relates to a quieter background and better imaging. Apartment living shares a lot of common noise throughout the wiring of the building. If you notice your gear sounding better at night, you could use some power conditioning. IMOI use a USB converter to AES/EBU so no noise for me. I also haven't noticed any power related noise. :blink:

:veryevil: the journey continues down the hobbyhole.Well HC as you know all I have are the Emotiva Power Cords at the moment. At this point I hear no noticeable noise. I'll compare once I get one of those isolation transformers. As for right now I would have to say to difference will be very subtle. We'll see.
I've been having some issues with my M51 when feeding my SRM-717 through balanced cables. The thought at this time is that I'm getting some DC that is tripping the 717 protection. I have a message into NAD and I plan to try and measure the output to see if I can confirm it.
Outside of that I am very happy with the M51 and hope to resolve this so I can continue to enjoy it!
