I'm looking at replacing my old Yamaha DSP-a5 receiver with a nice Pioneer 2011 or AX3 or equivalent. Before I put them up later in the week - for completely wrong prices - any ideas on the following items ? In the process I'm going to be selling my DSP-A5 - any idea on how much they're worth these days ? (before I spend too much on my new amp !) - I was thinking around 80-90 quid ? With box and manual and remote ? Also - if the Pioneer is even close to my NAD C350 for stereo playback - I'm fed up with using it as a power amp - how much do these fetch on the 2nd hand market - all boxes etc, + 2 years left of Richersounds warranty ? 140-150 ? I know these things all depend on whose looking for what items at any specific time - just looking for approximates Thanks, Mark.
