You need a Z-Systems RDP-1. Stop torturing yourself. We audiophiles are prone to that. I assure you, this will be some of the best money you spend when it comes to preserving your sanity.
But you'll also need an outboard DAC. This was Stereophile class A for a reason, and you still can't find anything else like it. It was 5k new but you can find them used around 1200 and up. 2k is not uncommon, but watch eBay for deals.
Read a few the glowing reviews:
