@blkwrxwgn - If you're hoping for great sound quality for 2-channel listening, I think you will be disappointed with the P6. It is feature rich, however ultimately sound quality is not it's forte.
Have you exhausted all of your troubleshooting of your current system? If you don't get hum playing sources other than HT through the Freya+, there is no reason why you should have noise when listening to HT. That is, unless the noise is coming from something in the HT receiver.
Have you tried just plugging another source component into the input of the freya+ that you use for HT bypass input? Don't forget to turn the volume down. If there is noise with another source component, you know the noise is likely from the Freya+ and could possibly be resolved by replacing the Freya+. However, if there is no noise with a different source plugged in directly into the input, you know the noise is coming from somewhere in the HT system.
BTW, your receiver is from a very high-end company and it is pretty expensive. Does it not provide adequate SQ for this purpose?
