I'm tired of my Marantz integrated and my Cambridge Audio CD player. I want
to upgrade my system piece meal and wanted to start with the amp.

I want to replace my speakers at some point in the future too, so I thought
perfect opportunity to swap an integrated for a pre/power combo.

I'm looking for a relatively cheap used power amp right now - eBay and
Audiogon are my destinations. I was thinking about the Adcom GFA-545 II. Any
opinions or experiences with this? It's got pretty decent reviews on
audioreview.com.

Any other recommendations? I suppose the type of brands I am limited to are
Rotel, NAD, Adcom, maybe Arcam. Ideally I would like to not spend more than
$275 to $300 on each unit, hence my desire to buy used.
