Best way to spend my money

I have used AntiCables interconnects for years, when I don’t want to make my own. Very good bang for the buck. Also I’d look at the “used” market. Cables don’t wear out.

I've checked on xlr cables like mogami and they are cheap enough, less than 100.00 for the pair....I guess the only question is what would be the best bang for my 900 left over...thr power supply which I can pickup for well under that or a new cartridge?

Not only is it affordable, but the Mogami like 2534 quad XLR cable (w/ Neutrik connector) is also one of the lowest-capacitance XLR cables available on the market.  Very dependable and sound good.

Mogami noted above is fine. Many of our treasured records experience mogami right after X microphone…. it’s good to have a few in inventory.

+1 on Mogami XLRs.  My suggestion would be to find a used (or new) SoundSmith MIMC Star cartridge. This cart should work with your phono pre and once they have 100 or so hours playing time on them, they really get holographic and sound amazing. That cartridge, like the Lyra Delos, made me want to explore the more expensive models in the respective lines. The process taught me about the law of diminishing returns. Both the Delos and the MIMC Star are super solid.  The MIMC Star is a little closer in sound to the Benz.  The Delos has that amazing Lyra openness on the top end.  

Anyway.  Have fun you cant loose.
