What is a turntable pad? It sounds like a cheap piece of foam under
the turntable would do the same thing. The loss of bass was originally
caused by audio feedback though the turntable. It is relatively easy to
cure, a piece of foam under the turntable. That $50 pad sounds like
a lot of money for such a simple problem.
Of course putting a pad under the CD player should have any effect...Yea digital

Um, thanks for the info, Bill, but could you elaborate a bit for those of us who don't get $ensible Sound?

Nononono, it's not put under the turntable. The pad is a rubber disc
that's placed on the turntable PLATTER, directly under the album. I
haven't heard one myself, but the people I've talked to described its
effects almost precisely as rayjay did.
I'm not certain why it makes such a difference. The theory I've heard
is that it reduces low-frequency vibration between the album and the platter,
thus cleaning up the bass. I don't know how it would compare to using
a platter weight on top of the album.
Does anyone know how Harmon-Kardon's "dead rubber" mats perform in this
respect? Their T45 and T60 have mats which they make all kinds of claims
about. They also provide a platter weight.

I find platter mats extremely useful. My turntable platter rings like a bell when there is no plattermat on it. Putting one one deadens it so that it will not add anything to the sound. A soft flexible mat helps here. A very sticky mat is desireable because the record stays in full contact with the pad and does not leave resonant cavities that add garbage to the music whenever the cartridge goes over that part of the record. The shape is very important because incomplete contact means any advantage of the mat is lost. I am personally against record weights unless the turntable is specifically designed for them. Excessive bearing wear can result if it is not designed for the extra weight. I prefer to use a clamp to hold down slightly warped records. Aside from the mat that came with my turntable, I have two others: the Eon Research Tripad (goes with the Tripod), and the Angstrom platter mat. Of the two, I prefer the Angstrom. It is similar in profile and material to the Platter Matter mat, but is made of conductive rubber. It comes with a small clamp and is a very good mat. I have not compared it to any ones other than the ones I own, but the difference is the bass is slightly tighter and the highs are more cleanly reproduced. Overall, the accuracy of my system is improved. This is not to say the other platter mat I have are bad, nor are they garbage. This one is simply better. Herb...
