Hey Jamiek ,,,
Hopefully you have picked the JRDG C500 over the MA7000,, because I owned both of them ,,, and I must say that MA7000 ... is just not an hi-end products.
The sound was just dark and flat... I am not sure if there is something wrong with my MA7000(Sold it right away I bought it based on all the reference on the net before I even heard it... bad move) bottom line C500 worked well withmy W/P 8 without any issues,,, MA7000 .. I tried it with HARBETH SHL5... when you try to go louder than 11' ,,, the sound is distorted.... its.. just not a good amp.. trust me I head it with both of my ears....
Sorry Mac,,, you look beautiful but for the money you have to go with JRDG, PERIOD.
