HT system with Best Possible Redbook perfornance

Arcam AVP-700
Cambridge Audio DVD-87
Blue Sky Big Blues with Pro desk rears.

Sounds better and costs less than your proposed used system and you can buy it new. B&W, your taste in music and the B&K are a poor match.

BTW the processor is good enough you won't have to listen in two channel to your music the PLII on the 700 is very good and can be tuned to outperform the 2 channel performance of any comparable system.

Redbook is easy, your surround processor is the DAC, so spend all the money on the processor and you will get better results than splitting the money between a Cd player and a processor. If you can find an AV8 or 568 or Anthem all super good prepros that you will be hardpressed to find better sound CDplayers in that price range. The Arcam prepro are essentially the same as their cd players d to a wise.

The Blue Sky's have their own amplifier built in, they are awesome for Depeche, Elvis, Gun's& Roses, because they will not clip and flap until insane volume levels the Arcam I suggested is just the prepro not a receiver. To be honest its just a smidge smoother than the B&K Ref50II which I also like very much.

So it doesn't matter which pre pro or receiver you buy its a win win. (B&K Arcam)

Just focus on the speakers, I too am foremost and 80's new wave rock guy too, Metallica, Sisters of mercy, Nitzer Ebb all bite it on mass market/ high end speakers that you see in Stereophile. Stereophile speakers rarely have the Cajones to hold it all together even with a solid receiver driving them like the B&K. mainly because they lack a solid dynamic midrange. I use ATC speaker because of that, the Blue Sky's are a poorman's ATC (forgive the lack of a better description)

BTW I listen in surround all the time, makes the music liquid and easy on the ear, even early REM and Smiths albums sound pretty good played in surround, better than the LP's that's for sure.
