Which turntable is better?

meanwhile, just listed, NOS Pioneer PL-600 in sealed box for $700.

I second whoever said to get a Rega P8 demo or maybe used from a dealer. The arm on that one is phenomenal. Just make sure you have it set up with as few vibrations as possible, ideally on a shelf or at least on a vibration control device if you're not sitting on a slab.

For the money, the Mofi Ultradeck is a great deal if bundled with the master tracker cart or above.  Prices have been significantly discounted lately. I like the Delrin platter material also.

Rega P6 if a fair buy. The used P8 will perform noticeably better.

I know the Technics 1200+ turntable series are a solid sonic audiophile choice, not so sure about lower models.

I would suggest this Marantz tt-15s1. I like some things about it.

It is at half-price, around $1500 at A4L.

Good luck.

Also, you should always have more than 1 turntable. Maybe, get a Technics at a later date.
