Achromat. Replace just your tired felt mat and immediately start re-invigorating your record collection
"Voices seem more natural and large ensembles of instruments are very well-defined and differentiated. Bass is roughly similar in weight and extension, but has less overhang and tonality is given a lift in precision across the frequency range."
– Richard Black, Tech Radar, July 2009
"Substituting the Achromat for the original rubber mat brings about immediate improvements. That probably understates the differences...Ambience retrieval, soundstage depth and width, the distinct pitch of individual bass notes, immediately grab this listener's attention as vastly improved. Vocals sound more like real human voices than processed vocals. It becomes easier to follow individual instrument lines, which seem better separated from rest of the mix."
– Mark Wheeler, TNT Audio
The stylus accelerates at up to 20,000g. This means your groove wall is not so much caressed but more akin to being pummelled by a road hammer creating travelling shock waves. When there is a material change (the record sitting on a felt mat, say, these waves are reflected and
energy reflected from the bottom of the record (a mere 2mm thick) is sensed by the stylus and heard as colouration.
Can we prevent his reflection?
Achromat is the ideal material to absorb energy from the record. There is no better.
But it is only 3-5mm thick and this is where the science kicks in.
Millions of tiny bubbles within create complex pathways and that's where the energy gets lost as heat.
In this way, Achromat acts like a considerably thicker mat. Its job is complete.
No other mat is like it and all it takes is a simple A-B comparison to demonstrate the differences against other supports.
Longer term listening allows subtle nuances as well as greater bass intelligibility to be appreciated.
In 2009 Achromat came top in a mat comparison in HiFi Choice and then went on to win the Gold Award for Accessory against all comers.
And of course there are the testimonials from happy customers.
It has become the mat of choice for LP12 owners and also Technics SL1200 turntables.
No wonder Achromat is the World's top selling mat.
Funk Firm Achromat 5mm (For turntables with arms with VTA adjustment) -
Achromat 5mm: The 5mm is the standard recommended thickness.
In tests it consistently comes top over the 3mm mat.
Not by a lot but it is noticeable.
So wherever possible go for the 5mm.
Achromat 3mm: Why the 3mm, then? Many people's turntables use arms with no VTA capability, whatsoever, notably Rega 250s & 300s. These turntables use felt mats that are about 3mm thick and so a special version of Achromat has been made available as a convenient way to get most of the benefits that Achromat has to offer.
Another reason is for those decks with short spindles and a clamp; the 5mm would cause problems.
On a metal or glass platter, replacing the usual felt or rubber mat, the Achromat gives a sound that is indeed considerably less coloured and also distinctly more detailed than before.Voices seem more natural and large ensembles of instruments are very well-defined and differentiated. Bass is roughly similar in weight and extension, but has less overhang and tonality is given a lift in precision across the frequency range. 5/5 Tech Radar
I then went even further: I added the Funk Firm Achromat, which combines a light and porous polymer fill with two sides of rigid skin, to form a record support that's intended to act as a nonreflective sink for the excess resonant energy thrown off by transduction. with my still-unmodified LP12, But now, the Achromat's strengths and those of the rest of the Funk kit seemed to pull in the same direction. With all the bits in place, it seemed as if one last impediment had been removed—and I could now hear virtually every aspect of the musical content, and the sonic presentation begin to jell.

LP 12 Owners, You Must Try This! Throw the Felt away! Don't waste time with the other mats. This one works!
