^ bingo...

 

^^^^^ so what u are trying to tell me is that u would sacrifice the quality of a regulated power supply for (dynamic head room) here is the deal. the regulated power supply is no worse for head room! in fact an amp that can quadruple it's out put at any given momoment is more than enough for any thing i can think of out there!

lets once again take the example of what is happening with non regulated. you have a long deep or hard note then the note will audibly drop off. i know that we have all heard this. 4 10 is a good example were that first hit is harder than the following ones. yet u will notice that there is no difference with the regulated supply, it stays linniear.

so going back to the whole non regulated and how many are winning out there. well quite frankly there are many companies out there and not every one wants to spring for that expence! for that matter most companies don't want to spend the money on such a good design. so bassed on that fact alone i would like to know how the whole how many systems are winning out there with regulated supplies is even a valad argument. u would have to have an equal # of compedators with equal talent and install abilities to make that a valad argument!

as far as guys who don't have major voltage drops. yes u are right bassed on the level that the system is being played at on average it is not a larg issue. regardless there is still a noticable amount of difference. all u have to do is put a voltmeter on the battery and u will prove this to your self.

If you have a loosly regulated amp and your gains are set properly you should not be able to run the amp into distortion even under heavy current draw with some V drop going on... All while gaining some extra power (headroom) over the regulated design...


In the case of an A/B class amplifier it is true that the regulated design may be more efficient at low output levels.... This is because an unregulated design may be holding unsutainable rail voltage levels that will sag under heavy draw....

Higher rails = more power dissapaited as heat at low levels... since the rails can't hold under high power whats the point of having it so high ?

This is relative... dynamics will still be improved over a regulated design..

Also, a regulated design will have more losses in the power supply, and as you mention they are more expensive to build...


SO... in an A/B class amp there are advantages and disadvantages to both designs (surprised?)


It would seem to me that in any other class of amp tight regulation is not benificial; and that is probably why you only see it in A/B designs...

^^^^i will take that with a grain of salt as u are a rf fan!

 

^^^that just doesn't sound like an educated reasoning. u will have to do better than they are crap. that is like me saying soup sucks! soo what about who made the soup or were is the soup from or what type of soup is it. or even how old is the soup. you are gonna have to do better than your vauge generalization.

Have you noticed that even Alpine uses non-regulated power supplies in some of their amps?

 

A regulated power supply will be cause for better SQ over an unregulated design? Please tell why that is.

And the 800a2 and 1100a2 in the For Sale section are studs of an amp. If you can get a good deal on them they would be a very good choice also. </font>[/QUOTE]the regulated power supply is better for sq do to the fact that regardless of the current draw that the battery is under the amp is still going to produce the same amount of power at the out put stage. this is obvously important with very dinamic music that contains a lot of lows. If u can't see the logic in that then i guess i just can't help u. [img]tongue.gif[/img] </font>[/QUOTE]Justin, to qoute you: If you can't see the logic in that then I guess we just can't help you.
