Harmonics TU-800 EX Turntable mat.


I am thinking of purchasing a Harmonics TT mat. It's only 1mm
thick but costly at $315 a piece. Michael Fremer likes it, he said it improves the liveliness of acrylic platters which he thinks sound soft in the base and congested overall. I'd very much like to hear your opinion if you are using this mat.

I'd also like to ask Fremer and all the TT manufacturers why has no one come up with an all vinyl platter of the same formula they use to press records? That would be the ideal impedance match.

I believe The Funk Firm has done just this. That's the principle behind the Achroplat and Achromat.

I have two friends that use the TU800 EXi and the even more costly Harmonix LP weight TU-812 (US$515). They use the mat on top of Micro-Seiki copper platters. They really like the TU-800 EXi and say the TU-812 weight makes it even better.
I had the new version Harmonix mat and the Boston Mat - Fremer must have the older version as i don't think it's soft or congested at all. If anything, it's too detailed and focus!
It is better than the Boston mat but doest cost more!!

I had both the Harmonix and Boston and I preferred the Harmonix to the Boston Mat1 by a wide margin. YMMV
I have to add that the Boston Mat1 is also a very good mat. It is extremely quiet. It takes away some of the harshness as well as some detail. That is my only complain with it.

Comparing it to the Harmonix, you will find the Boston to be bloated, muddy and compressed. Hi frequency detail is much rolled off. The Harmonix makes things more spacious, rounded and extended. Price wise, the Harmonix costs 50% more than the boston ($199 vs $315)so you have to take that into consideration too.
