hey all.....

i have doubt.....will there be a performance/quality of the sound, difference if i were to attach speakers capable of handling 150W RMS power,to a entry level receivers begining 75w RMS with the next level receivers of 90-100W RMS......apart from the features they offer......

please help me out with this matter.....
ur valuable suggestions are most welcome.....

If the reciever is from the same series, I think the difference would be felt only at high volumes. The dynamics do increase with a higher power amp but it would be applicable at higher volumes.

I don't think only because of power ratings there will be difference. Anyway you are not going to use 75W per channel

but there can be other factors...

it all depends on the amplifier quality and whether the amps have sufficient grunt to drive the speakers properly.

I have seen quite a few low powered amps beat the hell out of the higer powered so called better amps....

Completely agree with Manek..It is not the quantity of the power but its quality which matters.

Power is only half the story. You will typically gain 3db in volume with an amp with double the power. 3db is hardly audible. A perceived Doubling of volume(it seems to sound twice as loud to the ear takes a 10db increase...In other words looking at ou scale to achieve this doubling of a 32 Watt amp you would need around 320-400 Watts. Trouble is you're limited by the speakers MAXIMUM Watt level...most speakers are under 250 Watts...so if you want a truly deafening speaker you want one that has a high sensitivity and also takes a lot of watts...and preferably is an easy load across the audible range. What you gain from higher powered amps is more band-width and high-current capability to make the sound more natural and effortless without any strain. To achieve this, you will need a good power amp or a high quality integrated amp. Power-wise and musicality-wise you are not going to gain much if you move up to the next receiver model. It is marketing gimmick.

thanks alot guys for ur replies....

i am seeing the difference between Denon 2105 and marantz 4500 or 5500......both in the HT and Steroe modes.....please give ur suggestions on this too.....i felt the marantz is far more better when compared with denon1705 and marantz 4400.....both in surround and stereo modes......me, benkenobi and abhi pani had been together to the profx showroom for the auditioning between the 1705 and 4400......

Clearly the Marantz was better...no doubt about it..
the music was purer and clearer..
Felt the Denon to be straining and the highs were at times unbearable.

I would go a bit further on that. Infact I felt that the Denon and the Marantz were being compared only because they looked similar and both are 5.1 channel amps (elctronically) otherwise sonically they dont deserved to be compared at all. There was not a single instance or even a single frequency where the Denon could match the Marantz.

Some people may say that Denon is better in low frequency but even that is questionable as the marantz had real quality lows compared to the harsh lows of Denon.

Hope denonfreaker is not around.
