Andra's very nice speaker, I have not heard the 3's but owned the 2's and they are a great speaker indeed.
No problem with that room, I would recomend you look a a tube pre of some sort also.
Audio Research is very nice and pairs up nicely with Bryston, connected via balanced cables.
You can scan threw my threads and others in relation to both, I don't know many whom own the Andra 3's though.
