At the risk of appearing self serving (I have an item up for auction here on Audiogon that would profit form the folowing recommendation) may I suggest you consider separates at this price point. Besides some technical advantages separates would permit you the opportunity to customize your system and allow for greater flexibility for future upgrades.
500 to spend on int.amp,help me match with gear.
Currently using Yamaha RXV1000 to power PSB Alpha A/V (6ohms)with Music Hall MMF CD25 connected to 5.1 inputs. Current set up sounds a little harsh, and I like a smoother sound. AQ Diamondback ics, Monster Original speaker cables. I also dont want to mess with tubes. Would consider used SS stuff. Thanks for the help!
