Yeah, I was thinking again about you thinking your amp and speakers might be a little bit bright. I am looking to invest in a mains unit that filters noise out of the Mains supply. Something like this. The Tacima CS947 https://www.whathifi.com/best-buys/accessories/best-mains-products Since removing noise from the USB power lines on my DAC with the Jitterbug helped. I am looking to see if I can purify the mains electricity. The general impression of these mains products, is that pro-reviewers report the same thing. Better dynamics, and reduction in brightness. ... It's got to be worth a try. At the least, it's anti-surge protection. I am very interested also because the Rega Brio, which I have suffers a fraction of mains hum. A 50Hz signal very quietly in the speakers. I can hear it if I put an ear right next to the speakers. I can not hear it if I move my ear just a few centimetres away from the speakers. (Apparently this mains hum is not uncommon in amplifiers. Not that I ever remember it before.) ... However it will be enough to fractionally alter the sound. Regardless of this though, the Rega Brio is an exceptional amplifier, and has won many awards. No one says a bad word about it. .. It is truly amazing to listen to, from my experience. If one of these mains products can do anything, then I will be ecstatic. ... it might be what you are looking for, for your system. Although the Jitterbug might be enough to make you happy. Or any other noise reducing gadget. Someone mentioned that the Schitt WYRD works well, and it reviews well. There is also the iFi USB 3.0 line of products. They can work on 5V power supply to the Mojo to charge it. If you are playing and charging, who knows if it will help. Also you can use it to cure noise in the audio signal line. It re-clocks though, so hopefully it will not interfere with the Chord DAC sending for signals.
