I have been using one for about 3 months now. I can say for my system and my ears it is without a doupt the best thing I did for my humble analog. It has given me a quiter background and a wider soundstage. I am running this on a MMF-7 Pro-ject 9 Arm with a ZYX Airy 3 SB Lo. I have no idea where up the chain in tables and arms one would loose any benifits. I hope to move into a new table with a Moerch arm in the next few months. I will report back on that.
