This receiver just came out and seems like very capable/great value from Marantz:

They promise 50wpc into 8 ohms, but there is also a mysterious 'front bi-amp' mode they recommend using to improve 2ch listening.

Do you guys think this would be an ok "starter amp" for a set of Sierra Towers? It has pre outs so I could eventually use it to drive a much more powerful amp... but can I get by on 50wpc for now?
