Does a turntable mat make any difference?

It gets rid of the RC network between the transformers and will definitely extend the high end. The question is will my old ears be able to hear it. It will also take a big load off the MA 2s as the processor is pushing the amps to make high end up to the limit which I think is 6dB. Sorry folks for commandeering the thread.

The best mat will be heavy and have the hardness of vinyl. More important is that the record be firmly held to the mat. Reflex clamping as used by SME, Kuzma, Avid, Oracle and CS Port, or vacuum clamping as used by Sota, Basis and Techdas, are the best solution. Record weights are a half way solution. 

It will also take a big load off the MA 2s as the processor is pushing the amps to make high end up to the limit which I think is 6dB.

@mijostyn There's no energy up there- its not a significant load for the MA-2s.

@atmasphere 

From 5 kHz?

@mijostyn I might be confused. It happens easily. If you are planning to run the MA-2s 5K and above, it should do that fine. But I think it will do better 5K and below. At 5KHz and above there really isn't much musical energy, partially because our ears are pretty sensitive at 5-7Khz, and its mostly harmonics above that.

@atmasphere 

They are going to handle 5K and below. 5K and up is going to a Bricasti Design M25 which has a very low output impedance and doubles at least up to 2 ohms which is 600 watts. It has a HUGE power supply. I know the is less energy from 5K up, but you can not predict what the processor is going to do unless you have an amplitude graph of your Speaker/Room. Remember, I burned up (literally) a high frequency balance control with a processor that had no limits. Smoke and that acrid burning electronics smell. Whatever that takes to accomplish is what that JC 1 threw at that control. 1000 watts? The MA 2s are happy as a lark, this is where they do best with this speaker. What else can put 220 class A watts into 20 ohms. The JC 1s are down to about 75 watts at that impedance. And the MA 2s are rolled off at 100 Hz 48 8th order. They will be running 100 to 5000 Hz. I have the hottest midrange amps in town, with triggers no less.  The M25s have a crystalline high end like my old Krell KMA 100s. I can not believe this won't be an improvement. The only problem will be if I do not have enough room in the conduit for two more signal wires, it is 25 feet long:-(
