Well thought out system.
I especially like your idea of using JPS Labs wire from the electrical panel to your components.I can do this easily with my front end components.
Your music tastes are right up my alley.
I read were you purchase new and used LPs.
One thing I would like to suggest is a record cleaning machine,new or used along with using WalkerAudios Prelude record cleaning solution.
It is everything Lloyd Walker says it will do.
I will not play any LP new or used that I buy until I have cleaned it with this solution.
It is truly remarkable and could very well be equal to the results you got from using JPS Labs wire from your panel to your system.
I kid you not.
