SOTA I-clamp vs Reflex clamp

The Reflex clamp is way better than the i-Clamp. With the i-Clamp you just push down on it and turn the little knob on the top to keep it from moving.

The Reflex clamp actually grabs onto the spindle and when you lock it down it forces it's way down and locks the record tight. Plus, it's mass is higher and heavier and made like a tank. The i-Clamp is a light piece of plastic.

You wouldn't want to use the Reflex clamp on a lighter, sprung table.

I'll be using for a Thorens TD150... I wouldn't consider it lightly sprung.. But this is my first TT and I'd like to start out of the gate with the proper setup

One of the biggest mistakes I have made in audio is selling my SOTA Reflex Clamp. It is by far, the best clamp on the market for non-threaded spindles. If it were not for my VPI Aries being a threaded spindle type, I'd buy another but this time I would keep it for life!
Regards,

I have both, and use the Reflex exclusively on my Sapphire. I tried the I-Clamp on my PL-15D, and it just didn't work all that well on that, either. Went with an old Audiocraft SD-600 clamping weight for the Pioneer - much more satisfactory. In general, mass is your friend.

Good luck & happy listening!
