I have read some excellent suggestions here for you already I would also suggest a used Acurus A250 if you are truly go-ing to use the SonyES as your line drive.The potential of your speakers and front end will undoubtably show the Sony to be-a limit at any rate.If you do run across the Acurus in your shopping you may like the sound as well! Good Luck!
Need advice on amplifier upgrade
I currently have 802 matrix III,a rega planet cd player and a sony es receiver which I plan to upgrade soon. I'd like advice on which amps would match up well and whether I should go with an integrated amp or power amp using my sony as a pre amp until i can upgrade that down the road.
