I recently purchased a denon poa 1500 amp. I have a pair of onkyo m504's I used to bi amp some AR's I no longer own. I have an opportunity to pick up another 1500 but i'm not sure it's build quality and reliability are on a par with the onkyo...they both sound very nice....different....but neither is hard to listen to for extended periods. Any opinions in regards to reliability or overall quality. If I buy the other 1500 I won't keep the onkyo's
