Integrated or Separates on a budget

Blewis, do you have room for a separate amp with volume control (e.g., your integrated that you're trying to replace, or the McCormack Micro Line Drive that just sold for $260) to drive your dining room speakers? Then, you could use a spare line-out, like a tape out, from your main preamp or integrated amp. This would give you a much larger selection of pieces to choose from for your upgrade, and you could really concentrate on your hifi goals for your main system. I'm assuming you wouldn't have to be overly picky or spend-y about the quality of amplification and cabling to drive your dining room in-ceiling Polks.

Jayboard- I have the space, but not sure I understand the hookup you're suggesting. Can you be a bit more specific?

Also, any thoughts on the Arcam A90 or A80 (I know the A90 is likely out of my price range, but maybe not new).

I would stay away from seperates in your price range and look around for a used YBA Integre. 50 very sweet high current beautiful quality watts of the best in its' price range. I owned this baby for 7 years, and it delivered the goods until I needed more goods.
