Super Lumina has disrupted my normal advice. A friend is having his 500 upgraded and has a loaner NAP200DR feeding Kudos Titan's via Super Lumina speaker cable. Rest of the system is NDS+555PSx2 + Chord Music interconnects. The NAP200DR sounds miles better than his non-DR 500. The newer amps in combo with the SL speaker cable makes a sound I thought was not possible. While the 500DR is spectacular (I own one) I would suggest a more modest amp (250DR) in combo with SL cable + 552 preamp will make magic.
Are you saying that without SL 552L250DR doesn't work.
