Grungy sound with clean needle

Rshak...in my case the white paper that protects the wires and coils was actually touching the vinyl surface. Kinda easy to tell :-)

It was fine just the album side before and wham, the suspension was shot.

Has your suspension on the Denon S1 collapsed? I was in the middle of a listening session, (about 3 hours in) and all of a sudden the sound was horrible. Quicking checking everything, I had found that the suspension on my Lyra Delos had fallen.

The Delos only has about 200-250 hours on it and was meticulously maintained.

You might check this to be sure.
