Which amp for front speakers .

I have polk lsi15 modified fronts , anthem 20 processor , have a b&k ex442 and a ex4420 which amp for front 442 or 4420 for lsi 15's
If you own both amps then it should be easy enough to try them both. But I would lean towards the one you feel is more powerful, you need the most power in your front mains. Try one for a week, then swap and try the other for a week, or however long it takes for you to settle on an opinion, I would be interested to hear what you decide.

Thanks I ended up using ex4420 for surrounds and sold my 442.
