I have a showroom condition Rotel Rx-1603 receiver that I would like to trade for high end tube gear. I'm looking for a pre/power combo (preferrably Conrad Johnson, VTL, Manley, Sonic Frontiers, Cary, McIntosh, Audio Research or possibly Dynaco Mark III's). Let me know what you have if interested. This receiver I have is incredibly rare and in beautiful condition. I've seen these go for ridiculous amounts of money( up to $3000 usd.) Thanks, Kyle
