The Nait is an excellent integrated. Easily worth the price IMO. Not sure the Brio R has reached the US yet. According to a few people at Pink Fish Media, it's a big improvement over the Brio 3. It's a good bit more expensive, so hopefully it is a big improvement.
I was ready to buy a Nait 5i a few years back until I came across a second hand Bryston B60 for the right price. I've heard them side by side since I bought the B60 and have no regrets what so ever. The B60 has the PRaT and musicality, and adds more 3D imaging, bigger and deeper soundstaging, and sweeter highs to my ears. At a little less than 3x the price brand new, it should do these things and more. My B60 was 8 years old at the time (still had 12 years of Bryston's impeccable warranty) and cost about $500 less than a new Nait 5i. It was a no brainer to me.
Not trying to make you change what you're considering, just giving my experience. The Nait 5i and B60 are a lot closer to each other sonically than most realize IMO.
