More power does not mean better for all speakers...but good for most..right??..and a power amp like Aragon anyday is easier on tough loads than a 20 watter..well lets assume it's big room and gotta drive a low effc speakers at a reasonable audible level..then you need juice to drive them when some heavy passages dipping low are summoned..??

The above is definitely on the lines of what I was trying to say.but again there are 2 points above
1. Big Room (much greater than 15 X 12)
2. Low sensitivity (More relevant than efficiency) speakers ir less than 86 db Speakers

This is not a very common combination asz most speakers these days fall into the 86_90 db range ie moderately sensitive.

If you look at the entry level Aragons spec it does 200 W at 8 ohms and 300 W at 4.
Now most amps produce the best sound begining at around 30-40 % of peak power.. some even at 10%

so with such a huge amp in a reszonable room and average speakers you would be running the speaker for most of thetime in less than optimum sound.. not sure if that is a good match.

+Right point noted...My friend it really depends upon the speakers here again can't really push Dyn's in a fairly large room with a 20 watter..can you???...I guess the headroom is a hand in hand function between speakers and an amp..so an amp with limited headroom and low instantaneous current suffers to reproduce signals in a clear fashion...

Again let us look at " Headroom". that is the reserve power needs for sudden surges of POwer. some amps have it and some dont.
For class AB amps, it is purely dependant on thethe design of the Amp. eg a NAD and especially a NAIM is able to give out more than 3 times its power for dynamic spurts. that is because they are conservatively rated in their ratings AND they have better than usual power supplies.. something a Rega or a Puccini although with more delicate control do not have

For Class A Amps, headroom is limited, but since they are conducting full current all the time, the ability to sum up the reserve power quickly is very high that is whyè pure class A amps with small power ratings drive seemingly tougher loads easily

And 25 W in a 15X12 room is more than enough for a Dynaudio 52SE playing rock. I know this because i actually know someone in another forum running it as above (Incidentally a sugden A21a !!) !

But again of you have a speaker like a Wilson bensch or an ATC SCM35 and your room is 15 X 18 then you need an amp like the Aragorn (Even a Krell KAV series will not have the grunt). but for more "Regular" and budget speakers you do not need that much power.

So more power is better not for All speakers but only for those speakers which actually need that much more power ! Also a high quality 1 W is more important for most speaker than lots of power !

I wrote

but good for most..right

... I prefer to have an amp with much more than what speakers can take...I'm I commiting a mistake here???Agreed sir high quality 1 watt is better than distorted 10 watt ( a new one in our dictionary )...but back to my original post and to reiterate the excerpts...my argument was a product using famed Mondial Designs like Aragon and that too a dedicated power amp was behind Sugden in drive dept.yes the drive.no doubt I have respect for the quality 25 watts,the drive and the openess that doesn't mean Sugden has more reserves than Aragon??.....

sub, I understand what you are trying to say.. but the thing about reserve is, why are you holding the reserve and how much it is to be.. no doubt the Amp should have more power than the speaker , but how much more is the question.

Many 100 W amps do not sound powerful as for eg at say 25 Hz 4 ohms and if the phase is bad, it will struggle to produce even 30 W and hence sound cramped, but certain other amps although rated only 30 W will still produce 50 W of which only 30 is really required.(Especially true for Naim amps).

Suppose your amp were high quality like the Aragon, would you want a reserve of 200 W when in your room at 30 Hz and 4 Ohms all your speaker neeeds is 25 W ?

so you will find that a 100 W amp does not have the headroom but a 30 W amp has more than enough headroom !

in the end it depends on the speaker and the room

eg even if I had 104 db Klipshch horn but in a fully wood Panelled library with booksof size 20 X 25, i will need a powerful amp like the Aragon.

No I wouldn't need for Rf's atleast but quite interesting to see how T-amp gels??? any idea?

Thanks thats what I my argument started with..

I use the t Amp with a 90 db but 4 ohm speaker and need to use the volume Pot at 8 O clock in a 16 X 12 room

The T amp outputs around 15 W at 4 Ohms and around 9 W at 8 ohms. since your RF3s are 98 db ie they need 2-3 times less power in the same room size..the T amp should be more than adequate to drive them.

But the t-amp is tonally very neutral hence i suspect you may not like the high frequency response as the Klipsh is a by nature a bit peaky.
