Rega Brio-R Break-in time.

I just bought the new Rega Brio-R integrated amp. This is the third day I am using it now. I have been trying to burn it in but only have about 20 hours on it so far. I have mixed feelings with it so far. Everything sounds great except for one part. The upper midrange and lower treble sounds shrill, bright, and thin. It is unnatural. I wince when the T's and S's come on with singers. And with any instrument in that range it also sounds unnaturally bright. I'll give it another 100 hours or so. I really hope it changes with break in because the amp does so many other things right. My fingers are crossed.
Anyone else have any experience with Rega gear during break in?

Thanks Affinity. Would you suggest opamp and input caps modifications for the Rega Brio-R?

We have the Rega Brio R hooked up to a pair of Vandersteen 1CIs with Kimber Kable 8TC or 12 TC a Cary Exciter Dack
Peoples heads aree spinning when they hear this system.
If you hook it up with nuetral gear you wont miss the boat on what its all about.

Do you really want to void a Rega warranty? Caps are relatively simple to replace, but opamps are surface-mount. A real challenge. Maybe you could await a Rega factory mod (if it should arise)? Or select a different amp?

I suspected the issue with the Brio-R sound was due to the preamp stage and not the power amp. Thanks for that info Affinity.

I just picked up a brio-r and I'm having the same issue. It has a hard metallic edge compared to my old 2000 series brio. The 2000 brio is never bright or edgy sounding, the brio-r is tough to listen to on some material.

I do agree with Affinity, it definitely has the sound of polyester coupling caps.

I built a few phono preamps using polyester caps and those had the same characteristics.

I do love everything else about the R, it drives my Acoustat 2+2's to satisfying levels.
