"..I've heard the Titan make a good improvement to DSP6000s, an excellent improvement to DSP5500s, but kill a 559 amp stone dead".

George,

Dramatic claims like these do tend to foster the 'yes, it does; no, it doesn't' type of responses.

I assume in the case of the 559, that the fuse in the power cord had gone as this is the only circumstance I can think of where a power cord could make such a dramatic difference to the sound output. wink
