Hi, I've just salvaged some old Mission 780SE speakers from my loft. These were purchased in 1995 with a Kenwood KA3020 amp, which no longer works. I was thinking of buying a new amp to go with the bi-wired Missions, possibly to run an iPod through with decent interconnects. Does anyone have any ideas of what I should go for? Is the CA Azur 640A worthwhile, or should I go for something cheaper or second-hand?
