I am going to need some quick advice and comment please... I spot a MF A370 on the ebay for 499 from LintoneAudio. This might go up (bidding process). I will be using this to power up my 804s. It is about 18 yrs old. only have phonos into. It is big and heavy. 48.5 cm wide (at widest point which is front panel) 33 cm high 31.5 cm deep (from front panel to rear panel) 38 cm deep (if you include the handles on the front and sockets on the rear) about 30 kg. I dont know much about the amp and can judge if they will sound good and efficient. it is rated at 185 watts x 2 pure class A Just wonder if there is any pro or con about buying this amp.
