Hi all. I just bought myself a used, although fairly new, Pro-ject Tube Box II.

However, sadly, he sound when I tested it was downright horrible. The sound is extremely distorted and I noticed that the overall volume is now increased a lot while running through the Tube Box.

I adjusted the button on the back of the Tube Box to MM to correspond with my Ortofon 2M Blue pickup and hooked it up with my existing amp.

I have connected the Tube Box to my existing amp, a Denon DRA-425R. This amp already has build in RIAA. Could this somehow mess up the sound? I think the older Tube Boxes had some switches that needed to be adjusted to the corresponding pick up, but I don't see this feature on my box, so I guess that cannot be the problem.

Hoping for some help.
