Plz advise on Denon PRA 1500/POA 2400

Wow thanks for all the replies, actually I typed in more questions but seems cut off. Anyway thanks Mechans for the details, at least now I understand their functions.

To;Hifiman5- As a newbie comparing my old integrated amp vs the denon is a world of difference in sound quality. Low,mid,highs & bass has so much clarity. And there is no audible back ground noise/distortion no matter at what levels.For the price I paid, it's performance certainly is well over my expectations. Btw what's a high current design, I only know that this poa2400 is 500 watt. And I am just using a pair of Wharfedale diamond 10.1 speakers is it suitable?

Willland: Yes for the volume I have the same oncethe volume pass after 9'o clock the power just rocks all the way! The previous owner was using a pair of vintage Klipsch floorstanders not sure of the model but he told me was 98db as well, should be the best combo as yours.

As for the poa 2400,
-do I have to set the gain at max or if I set both channels at half when listening at low volume any difference?

-At low levels this amp is actually hotter then when listening loud ?

-Is there any servicing for this 20+ yr old amp to keep it
in tip top condition. Or only fix when spoiled?

Thanks guys

Hi Hifiman5- sorry think the poa 2400 consumes 500 watt but is putting out 200wpc into 8ohms.I read that too much power wouldn't blow up the speakers. But a audio shop guy actually told me I would blow up my speakers since they are only 100 watts /6ohms speakers. Any idea? But I normally wouldn't even go pass half the volume.

Thanks Bill will certainly keep that in mind.

Ok thanks got a clearer picture now. Anyway u guys know anything about setting the gain levels on the poa2400. If I set it at half gain instead of max gain on the power amp am I running at half it's amp power? Cos it tends to run quite hot after pro-long listening and sometimes at night I am only listening at low volume. Does it make any difference? Also mostly on the left side of the amp is hot. The right side runs quite cool find it quite weird. Comparing to my denon avr once it heats up the whole top side of the amp is hot. Any idea?

Ok thanks. I was still wondering could it's heat on 1 side of the amp be due to I am using speaker A only.
