A few years ago I was in the same position as you are now. I had a TW Raven GT SE with the AC platter and Black Night battery PSU. This PSU gave me lots of trouble, even after returning it twice to the manufacturer for repair. So I decided to sell it. I know I’ll be at the receiving end of demeaning comments from certain folks here, but I decided to try my luck with an old Micro RX-1500. Even in it’s basic form with aluminum platter the sound was surprisingly good. This made me decide to upgrade the table with stainless steel platter, copper mat, R-15 mass loaded feet and brass outer flywheel ring. I also had the motor drive fully refurbished. There’s plenty of space for up to 4 tonearms. The required gunmetal armboards are fairly easy to find and there are 1 on 1 replicas as well. In this fully dressed up version the RX-1500 runs circles around the TW, no comparison. Very important part of this outcome has been the use the SF-1 Kevlar belt. String drive will be equally good, but don’t use the standard rubber belt.
Of course the Micro can be easily dismissed as ‘old school’ technology, but I haven’t regretted this backward step for a micro second. It has secured itself firmly as my proverbial ‘last table’. And with your budget you can easily stretch to an RX-5000, assuming your rack can handle the weight.
