Don't be too quick to give up on the Grado. It is a decent cartridge. If you buy a used package of tt/arm/cart as you suggested, your choices will be more limited. That Grado in a good arm, on a good tt, will sound a lot better than it did on your MMF5. Then decide on a phono pre, and that choice will determine to a great extent your choice for a better cartridge.
Best way to spend $2k on a used Turntable & Arm?
I have a limited budget to spend on a used table and arm combo. I have a new Grado $120 cart. but could consider a complete outfit incl. cart. for $2k. I have liked the sound of the Sotas and perhaps Linn but think that I like the sound of the Sota better. I am curious about maybe VPI, Rega or Clearaudio, or anything that will maximize performance in this limited price range. I used to own a Music Hall MMF 5 but was not knocked out with it. Of course I like tubes and will get a phono pre separately. Thanks for the help.
