Well holy crap, this thing works.
First impression after insertion is yes, I hear a difference. It is a more analog sound, everything is smoothed over, but possibly too much so? I thought on some bright and edgy tracks this is exactly what I have been looking for, but on others they sounded perfect already, so this may roll off the treble too much?
After 2 days of running I am astounded this tiny little passive block of metal is doing as much as I hear it doing. I mean I already have an Etherregen, and a SoTM ethernet cable with its filter, how much more "filtering" do I need? Apparently lots. Not going to give any adjectives, not going to print any exclamation marks, but I am not going to use the money back guarantee- it’s staying. My digital front end retails for about 30K, and this little 200 British pound black box makes it sound 9-18% better. If it gets even better after a few hundred hours, like many components do, I am going to freak. Seriously, people spend 5k to upgrade their DAC to get this type of improvement. Thanks for the thread @ozzy.
