Just a follow up to my original post. Those who say upgrade the DAC have no clue what the NAD M2 amplifier is. It is a DAC on steroids. It is purely digital built in collaboration with Diodes Zetex. Since it only sold for one year, I doubt anybody here has actually heard it.
For @2psyop the Audiogon detective go to my Instagram and look at the photos of my two systems. Satisfied? I had the Herron/Tetra in my condo but took it to my cabin where there is more room and sounds a lot better. The smaller system is now in my condo. I did try the transport in my cabin system but I already have an Audiolab CD player and my Rega RP7 turntable.
In the end I purchased a Primare DD35. I am still on the fence if I like it. The build quality is top notch but the sound is different than my Aurender. It is a little bass heavy that I am not fond of. A/B testing between the CD and a FLAC file is quite noticeable. In hindsight I think I needed to put more money into a transport to better the Aurender. Live and learn.
