Rega Brio R bright???

Hello,

I have a Rega Brio R on home demo with a pair of exites X12 and a RDAC. But i find that it sounds bright. I saw two topics with the same issues. The majority of the reviews/impressions say that this amp is all but bright. Didn't found an answer yet. I tried other sources but the problem remains.

Tomarrow i wil post a review about the sound and feel of the amp.

Do you guys have tips or ideas on what to do next?
