if the avi falls over......

my point was that at maximum current draw it would very loud and your speakers might be in bits around you, that's assuming you can derive 26A of course

possibly this is why it has a captive mains lead? so joe schmoe won;t go an hook it up with his mini systems lead by accident? also if you're going to drop that kind of money on a borg cube of an amp then installing a new consumer unit and spur for a few hundred quid is peanuts really.

the only krell amp i've heard was a 300il which was nice in a very boring kind of way. that said a 700cx is at the opposite end of the spectrum so it may sound different.

My bro's Chords had 2 big 40 amp? IEC's on each mono block, lot of juice man, maybe they should listen to some serious class 'T' s :) all the power very little waste and heat loss :) plus the sound......:) Wm
 
Class D/T can be 90% efficient at all output levels, unlike Class A/AB/B. But if you Class D/T can do 2800W into 2Ohms it still needs 10/9*2800W from the mains. Which is a full kettle lead.

In much the same way I presume that Brik's don't NEED mana and electronics dont NEED clean power.

(Explain to me where 'clean power' comes from and what 'clean' means. And why you are happy to use equipment with incompetently designed PSUs.)

No Louder than you Paul, we all know that we usually use only a fraction of a watt anyway. My speakers are 89dbw efficiency, 8ohm load. I typically listen at 75db 2 metres away. How much power do I need then Paul, and why?

Clean power comes form the electricity board I believe, but I don't know what equiment you are referring to when you say incompetently designed PSUs. I don't have any Linn.

Now please explain to me why an oversized transformer sounds better 9 times out of 10.

I am genuinely interested in how you came to your conclusion, I know you are highly experienced when it comes to the threoretical side of electronics so your opinion would be appreciated.
 
Looks like typical American 'look at the size of my penis' crap.
 
80W/8 Ohm is a sweet spot on the conventional power amplifier output device chart, you only need a single pair, power can be good into 4 or 2 Ohms etc etc.

So, IMO, there's quite a powerful (sic) argument for making 80W as much power as you need.

And with 89dbW speakers and a normal room you can do yourself an aural injury with a mere 80W. So everyone's a winner. Make that a good 80W though...

It can never hurt to have a good connection to the mains, the minimum number of fuses for safety etc. But what does 'clean' mean? One could filter it to a lovely sine wave but if the impedance is increased is that obviously a good thing? I think the place for 'power conditioning' is in the equipment's PSU. If external conditioning always makes it better then that is a sign that the PSU isn't adequate.

just to provide a united front... hmmm that 80 wpc, single output pair (fully regulated?) amplifier sounds frighteningly familiar. wonder what it could be?

A very valid point, unfortunately until the manufacturers do something about, we have to find our own way around the problem, and foot the bill:rolleyes:
 
hmm its interesting to note that a linear power supply has a big transformer, read inductor in it, this theoretically should act as a filter in itself for mains crap, add to this, the design of circuits following op-amps lead for low power supply susceptibility...and regulators which further reduce psu variations,
and for a while I was rather anti any superfluous extraneous conditioners a la RA psuedoscientific bullshit, for the above reasons, however, the fact that systems sound different at different times, and other bits does lead me to believe that these external bits by respectable companies such as trichord or the pro audio people who make the trichord...have a look in sound on sound magazine for the same model, different name,could be well useful.

I'm sure there's more than one...

What's nice is that there are very many different schools of thought on this.

paul,
(with tongue firmly jammed in cheek and rabid naimie hat on...) but there is only one done properly ;) . gibber rant froth...
