The analogue trail consists of three elements:
Cartridge: Ortofon 2M Red
Turntable/arm combination: Pro-Ject Classic Cherry
Pre-amplifier: Pro-Ject USB II Box

I noted before some problems playing certain passages on vinyl, but I've checked the sound against the same track on CD and the roughness is there too, so I'm wondering if the problem is elsewhere, possible in the amplification or speakers. Even so, it's the same through the head-amp and headphones, so maybe it's the recording itself. Since it seems confined to one recording in particular maybe that's it.


The analogue trail to the amplifier is carried using QED Silver Spiral leads. These are a heritage item and are no longer in production. I've had them for years and have yet to hear a reason to upgrade them. I'm a pragmatist when it comes to cables ... I belive in solid, good quality cables, but don't buy the rather exotic claims of the type of cable which probably cost more than your electronic components.
Next: the CD trail ...
