btw Matt, the Trina are not intended for amplifiers. possibly the reason for the flabby bass.
not sure if you tried them only on sources or preamps by themselves. when I read your comments last week somehow I missed that detail.
if you still have them give that a try. if you did then we just move on. i continue to be very impressed by what they do in my system, where they are under my -3- Select II boxes plus under both my Tripoint units, the Elite and Troy Sig.
every system context is unique with tweaks for sure.
