Hey guys Been a long time since I've posted... Anyhoo... I've been giving serious thought to upgrading my setup (you can click my profile to see what I'm running right now). I'm looking at a Jolida JD-5T line stage and JD-9A phono preamp, Marantz SA8004 SA-CD player, Paradigm Monitor 9 V4 (or earlier. Used if I can find a pair). What I am unsure about is a choice of power amps. Right now it is a race between the Adcom GFA 555, Acurus A-250 and Integra M-506 (or M-508). Just not sure which one to go with. What are your opinions? Thanks in advance.
