Record weights

I have one one in use on my linn lp 12.I don't think i can ever go without it.In terms of cost it puts many cartridges to shame without it.I feel from my experience/opinion it is without a doubt a 200.00 steel compared to a high dollar mc cartridge.I have not tried it with a mega buck cartridge.It relaxes and opens up . Airy with no glare. Today i played an old lp and heard new stuff that had never before emerged.I had to run errands this am but had trouble leaving after a few tracks.WOW.Highly recommended.R.W.

Well the best is probably the Durand record weight which weighs 550g, but costs $3500US! I also like the Combak TU-812MX “Million” Maestro Analog Record Clamp which weighs 360g, but again not cheap ($3kUS). I own a few Stillpoints Ultra LPI’s which Roy Gregory raved about. The LPI weighs 680g & are a lot cheaper ($550).

I love the KAB record clamp, ~$35.  It uses a tight coupling to hold the LP down, not wieght, and it has a neat little bubble level built in.  Especially useful for suspended 'tables.  I have used it for about 6 years without any issues.  Cheap and cheerful, as they say.

I own and love the Durand -- seems like a good weight -- low enough that I can still use it on my spring suspended EAR turntable but high enough that it couples well -- it outperformed the Oyaide weight in my head to head comparison

melbguy, Why, pray tell us, is the Durand record weight "probably the best"?  I actually think it is not a well thought out product (for reasons outlined below), but I would never say it could not "sound good" (which can mean anything to anyone); I would say that almost anything you can make or buy would be as good, if weight is a determinant of the good.  Likewise to Shun Mook and MPingo. Puhleeze! 

Folkfreak, My beef with the Durand, right or wrong, is just the opposite of what you say (that it couples well).  Correctly if I am wrong, but does it not have an array of small ball-shaped spacers, mounted into the bottom surface at regular intervals around the circumference?  Seems to me these stand-offs elevate the weight off the label, thereby greatly reducing its capacity to "couple" to the LP and soak up spurious energy.

As to the OP's question, I would say that weight of 400 to 500g is all you need.  I use a SOTA record clamp and/or the record weight made for the Kenwood L07D.  They both work well enough.  I would not say that one is better or worse than the other.
