Rega Brio weird sound

I am familiar with the Cornwall and find them excessively bright with their EV metal horn tweeters

The new Cornwall is nothing like older Klipsch design. It has a smooth top end. Ny older Chorus II would cut my ear of at high level. Intense bright and shrill.

I had an Hegel before that sounded really good. Clean and neutral but the extreme damping factor of the Hegel amp made the bass disappear at low to medium volume. The Brio is just a tempoary solution saving up for a better amp. But I must say Im really disappointed with its sound after reading all the hype in the audio press. 

Its not defective. The hiss is not high but I hear ut from listning position. I have speakers with high sensitivity
