Record Clamps, which one and why?
I've been very interested in the effects of different types of record clamps. Some are marketed as clamps, others as stabilizers and then ther are some that are marketed as weights. So what's the deal?
Technics SP-10 with Myrtle cutom made 3.25" thick plinth, separate arm pod made of Ebony with a leadshot filled inner cavity and an SME Imprved 2009 Series IIIs arm, Cardas rewired. Jelco headshell with the new Cartridge Man Isolator. Lots of other tweaks, too many to mention here, now.
Thorens TD-316, split plinth, solid wood design using Leafsprings instead of coil springs. A superior design IMPO.
Ariston RD-40, three spring, suspended two part aluminum plinth with heavy platter, modified-highly tweaked Rega RB300, Cardas wired with junction box, RCA-all Cardas.
Several LOMC, HOMC and MM cartridges, vintage and new.
Of the three turntables I'm currently using, one is high torque direct drive with no suspension, the other is a suspended belt drive with old tired springs and the third a leafspring suspended table. The use of a clamp has always proven to change the sound, but I'm not exactly sure that the change is necesarily one that benefits the sound. Yes, a record weight can help to flatten a warped record, but so can a steam shower while spinning on an old turntable.
Using a weight stresses the suspension of my belt drive and possibly the bearing too. And it requires that the suspension be readjusted to compensate. But then because the springs have to be tightened to compensate the suspension aspect of the turntable becomes hindered because freeplay is very limited leaving the tables suspension too taught and overly sensitive to vibration and foot falls.
Using a clamp seems to make an improvement but because the mass is so much less than a weight, if it doesn't firmly grasp the spindle there is no sonic benefit at all. If the record is warped and you don't have a steam set up, suddenly the weight seems like a better idea.
Using a Stabilizer like the Thorens which uses mass evenly distributed to the outside edges of a record label when the stabilizer is mounted and is theoretically designed to flatten records and increase inertia and dampen vibrations. I'm not really convinced that these stabilizers stabalize anything.
So, here is a list of some of the more common clamps I've tried. Not a complete list mind you because some were DIY, but most of these names you will recognize if you're in to vinyl. I can't say that any one of them is better than the other, can you? But I left what in my opinion is a brief explanation of what my experiences were. You can decide for yourself, that's what makes this hobby fun and us all different with different tastes. Love to hear of any others not on this list too. Is this even a provable subject. None of these accessories has anything other than a clever explanation of what does in Theory.
Sota-Reflex, a good clamp but I don't see justification for price
PIG-cheap awesome clamp made by KAB I think
Thorens-expensive eye candy, that's about all
Harmonix-same
Souther
Clearaudio-All, didn't keep any
Pro-ject Puck-The only one worth its price tag
JA Michell-I can make a better, cheaper one with Home Depot parts
TT Weights-Just machined eye candy, no real science here
Bren1-No science here either, priced to high for what it is
Rek o kut-made a great vintage prof clamp rare but really good
Mapleshade-Good high mass clamp similar to the pro-ject
Locus Design-A really nice design, definitly makes improvements
VPI-Great for VPI tables only, same with Music Hall
Denon-Awesome little weight/clamp, very hard to find.
Misc. $20-$55 ebay Brass, Copper, Lead/Lead filled. some with bubble levels, many out of Honk Kong with names never heard of, some never to be heard of again-Actually some were pretty good.
My personal favorites are both made of Hardwoods and were DIY projects. One was a design to be made of aluminum but I had a very thick chunk of Ebony so I had one machined, then machined a cavity in the middle close to the base to experiment with leadshot, silica sand, pebbles, marbles, etc. And I've had some great results worth sharing with anyone interested.
