I have both the Rose rs150B and rs250 which I love. The only thing is that the 250 does the same as the 150B (as far as I can tell} and is half the price as well as half the size. Every morning I stream internet radio which sounds great through the 150B. I also use the Marantz NA7004 to play music elsewhere with great sound but annoying because it takes 4 minutes to load up.
It was the blue VU meters that made me want it.... you have to love them... the rs250 also has them.
