As you've already considered, changing out the acrylic platter would be something to improve on.
Maybe the challenge of building a platter will keep me happy for a while. I have to admit I got (almost!) as much enjoyment out of the build as I do out of listening to it.
That you're even asking the question tells me the answer - for crying out loud, keep it.
Yea, I know it sounds like that. but lately I've been getting that itchy feeling that says get rid of everything and start over. As much as I like my Audio Note kit, I haven't thought twice about getting rid of it and starting over. I'm going to have to give this some serious thought.
