Another mat you might want to try is the TTM mat and oil filled clamp. That is better than the CU180. More refined sounding. The cu180 by itself is probably the second best thing to the TTM. I have not had the opportunity to try the cu500.
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.
