OK ~ I’ll be that guy 😉
No disrespect intended, just an option for maximizing musical resolution, image bloom and all around enjoyment with inherent isolation much improved over your existing Pro-Ject.
If you’re married to the Darlington Labs MP-7 phono preamp (not knocking it!), I’d suggest the best Grado High Output pickup you could afford after acquiring a Technics 1200G. Toss the current tungsten polymer record mat from Luxman on it followed by your favorite records.
While not sexy by audiophile standards, it would serve up the goods and the Americans who import these Japanese products are great guys.
@needfreestuff is correct to mention phono cables 👍 lots of good inexpensive solutions (such as Mogami) on this forum.
