SP-10 Mat


I have an SP-10 with a Micro-Seiki copper mat. Now that my system is dialed in in terms of room acoustic treatments and speaker placement I find the Micro-Seiki mat to be a bit too lively but outstanding in terms of dynamics and soundstage. The stock rubber mat is too dull and bloated.

Could someone suggest a mat that falls in between the two, leaning more towards the copper mat sound than stock but less forward in the midrange and treble.

Dear Lewm: +++++ " I always have found that the really heavy gravity-dependent record weights suck life out of the music. " +++++

other people like you do not likes vacuum type mats because similar reason.

Could be interesting that we ask our self: need we a mat/clamp , why?

Which is the function of a mat: IMHO to present a better mate/match to the LP when the stylus is riding the LP grooves " eliminating " TT feedback platter/bearing and mat feedback to the cartridge during playback. So this could tell us that the mat must be as a damper tool with out self additional minute resonances/vibrations on playback.

From that point of view metal mats could be the worst ones ( as the MS and others. Metal here is the MUSIC information enemy. ), metal tends to resonate when in motion and because the stylus/LP vibrations that return to the cartridge due that the metal can't damp it.
Jarret said about: " bit too lively but outstanding in terms of dynamics and soundstage " , that " feeling " of dynamics is no other thing that additional distoritons but not MUSIC grooves information.

You said some clamps " suck out life out of the music ": too much damping????

Lewm, what could be what we are looking trough the mat/clamp kind of help?:

that through the cartridge obtain the MUSIC information recorded in the grooves with out adding or losting " nothing ".
The cartridge stylus/cantilever riding groove modulations generate non musical vibrations in the LP that goes to the mat/clamp/TT platter and return to the cartridge along TT self vibrations/resonances. All these kind of non-musical information degrade the cartridge signal, so we need " something " that really could damp it. A good designed mat is supposed that was designed to makes exactly that: damp.

IMHO, we can't overdamp the cartridge/LP during playback but through several years our brain is accustomed to those non-musical information ( added distortions, non-damped ones. ) and when we really damp down there what we listen is that " suck life out of the music " but is not because an " overdamping " subject but because non-musical information tends to disappears and that's why we don't like it. Of course that a heavy clamp other than damp it changes frequency resonances between the LP and cartridge/TT platter and create other kind of resonances/distortions.
In the other side that " suck life out... " could be because it's the way the LP was recorded it's the way must be heard.

It is not easy to re-equalize our brain for non-distortions ( lower ones. ) in what we are listening trough each one audio system.

There is a lot to discuss on the whole subject and certainly different points of view.

Regards and enjoy the music,
