I'm now at the point where an amp would be my next upgrade & really not sure what would be the best way to go. How much power would I need 100-125-150-200 watts? I will use my Denon AVR2802 for now & run my rear channel with it. Would you suggest 2-3-5 channel to start? Budget is around $1500 75% HT 25% music My speakers are: Mirage OM-7 Fronts 30Hz-20KHz @ 6ohms 90db Mirage OM-C2 Center 38Hz-22KHz @ 8 ohms 91db Mirage OM-R2 Sides 80Hz-22KHz @ 8 ohms 90db Mirage OM-C3 Rear 40Hz-22KHz @ 8 ohms 91db I'm leery of purchasing used on Audiogon etc.
