Soliloqueen's k87(k67) and k47 capsules

[tomas.borgstrom]

Well, compared to ribbons, which were the main vocal mics at the time, they were quite sibilant.

Microtech Geffel, who sells mics (or used to) with M7 capsules in PVC, used to say that those mics fall out of spec. and the capsule needs replacement after a while.

Indeed, some people like the lack of bass that is associated with old membranes, for close-up vocals, though.

Just so you don’t get me wrong. I don’t like those capsules at all. I send them for reskin. As I said. I’ve heard two with maintained low end. I’ve also seen and heard twenty year old dried Gefell M7 that sounded very brittle. An expensive product that deteriorates so fast is not acceptable.

I think the PVC debate is an obsession. I don’t work with membranes myself but those who do say it’s a terrible material for that application. Neumann gave up in the 50’s.

I’m sure Arienne can give us a much longer explanation on this topic.

Mylar. Drefahl does not do PVC. I've heard a few M7 with the original membrane in good shape. To my ears the M7 reskinned by Drefahl sound the same. Thiersch blue line (PVC) does not sound like Neumann Berlin M7 at all.

Thumb up for the Peter Drefahl work. My experience with his reskins is the same.

So for some of you, Drefahl skinned 3U M7 is where it’s at? If so, got 3U… Mailing is not a problem.
