Acoustic Signature Turntables

Hi Dgob,

It seems that there is a frequency shift with the Mat1, but at least in my system, it was not toward a higher pitch. So a contralto sounded like a contralto in my particular case.

There was though some sort of compression in the lower treble and the bass was not as deep, fast, and tight as it is with the Mat2. The Mat2 is closer to using no mat at all with the Mambo, while being more quiet than the Mambo platter with the Silencer inserts.

I don't notice a frequency shift with the Mat2, but I still need to listen more to be 100% sure about this. I haven't had the Mat2 for much time since there was a bit of a delay with the shipment due to the relocation of the Boston Audio factory.

Hi Isanchez,

I will wait to hear your final verdict before making any purchase then.

All the best and I look forward to hearing back when you're 100% sure.

All the best

Hi Dgob,

I'm sending my Mat2 back to the factory for an exchange because mine had a little dent that looks like a gap in the graphite. It'll probably take about 10 days for the exchange process.

At the moment, I have the Audio Technica AT-600 Ceramic TT Mat on the Mambo. This is a mat that I haven't spend much time with. I haven't done A/B comparisons with the Mat2, but at least in my system, it compares vavorably to the SAEC SS-300 mat.

I listened to Diana Krall today and there is no shift in her voice that I could detect. I've been to one of her concerts and her voice via the Mat2 seems to have the same pitch as with her voice in the live concert I went to few years ago. The same I could say about the Mat1, as far as I can remember.

There seems to be an emphasis on the mid-range with either the Mat1 or the Mat2, when compared to the SAEC and the Audio Technica mats.

Hi Isanchez,

Sorry to hear about the fault. I look forward to hearing your feedback after you've received the new one and had time to audition it fully.

Cheers

Hi dgob,

The Mat2 replacement should be arriving soon. In the meantime, I decided to give the Silencer platter another try. To my surprise, it is remarkably great. For some reason, the sound is quieter with more detail and more definition and extension a both ends of the audio band.

I understand now your pitch difference perception. The naked Silencer platter on the Mambo is spot on when it comes to pitch definition. I achieved this by using the Grip MKII clamp. I found this clamp to be the best match for the platter without a mat.

I have to yet do the A/B comparison between the naked Silencer platter and the Mat2. I shall find out when I get the Mat2 back.

Best,

iSanchez
