I assume that you are getting a lot more bass and sound staging from you CD player so you are sure that you are not limited by your amplifier preamplifier and speakers.
Upgrade from TW Acustic Raven AC-3 to what?
I have had the TW turntable (with 10" Da Vinci Grandezza arm and Grandezza cartridge) for two years. I have been happy with this TT and can live with it for a long time although i wish it wasn't as dark sounding, that the soundstage could be more spacious and the bass tighter. The upgrade bug in me is wondering for 50K ore thereabout, is there a TT that is superlative over the TW? One that would end my upgrading itch for the next 10 years?
