Albert Porters after market panzerholz plinths

Lewm and John what you say makes sense to me I'll pass on using the micro and try something close to the weight of the original mat when I get to that stage
Mikelavigne interesting line up of arms and tables I take it one or two in your line up plays large scale music better then other?

I use a SAEC SS300 metal mat on my Mk2 and Denon DP80. Weighs a bit over 1 lb and seems to be well tolerated in both cases.

Mike, I presume Steve Dobbins made your beautiful copper mats. (Well, he surely made the one on The Beat.) Does he sell them to the general public, or only to those who purchase a larger enchilada?

All I can say with all this talk about plinths etc, I sure am glad I bought a table from a company that actually spent time and $$ building an integrated table, plinth and tonearm that takes away all this stress and sounds absolutley world class to boot.

I am sure lewm will chime in here. Lew, how would you describe thye sound of your LD-07? I keep thinking dymanicel, but lacking in low level harmonics and tone - but I am probably wrong. How do you find the intergrated tonearm?

cheers

the copper-tops are platter surfaces, not mats. Steve sells a Garrard 301 copper-top platter that lowers the noise floor 4-5 db compared to a stock platter and sounds great. i don't think he makes any copper mats that i know of.

all three tt's do large scale music nicely; maybe the Rockport slightly more nicely as it can separate musical lines in a cresendo like no other tt's i've heard. low noise, amazingly stable soundstage, perfectly flat record.

I use the CU 180 on my Mk III and my Mk II. They are actually made of Gunmetal and sound slightly more alive than copper. The performance of the Mk II improves substantially with the CU 180 mat. Maybe I have been lucky but to date no sonic issues with the added weight.

I also have used a copper mat on my Garrard 301 beneath the stock rubber mat with good results. I believe this adds substantial mass to the platter in essence damping the chatter of the original aluminum platter and lowering the noise floor. I have listened to the Garrard without the stock rubber mat only the copper mat and prefer it with both. Once again no problem with the extra weight on the Garrard.

I would like to try a CU 180 on the Garrard, but have not to date tried one
because the CU 180 does not fit the spindle of the Garrard and needs modifying.

All the turntables are mounted in Porter panzerholst bases.
