Cleanest sounding amplifiers

[EFFENDI 10+ year member]

Please dont revive this argument again!!

Read the thread that DBFan187 posted..

..it has been discussed.

what happened to Tru, Audison, Zapco, Arc, Phoenix Gold, Brax, US Amps, McIntosh, etc....

how come no one mention these?? i know some of these are just in another league, but i thought these are all very clean amps...

Riddle me this:
If amps don't affect SQ, then how can you explain the fact that *most* car audio class D amps aren't recommended to be played above ~500hz...............

isnt it something like the digital switching going on cant go fast enough for it to play high pitched tones? like the switching tone as it is is something like 47,000hz? i dunno...

If that's your idea of a stumper, you don't even understand the debate.

Looked at any of the Xtant "Xtant" Series amps yet?

How about the old Infinity Amps?

Full Range Class D.

All comes down to switching frequency. Get it high enough, and you bet it'll do full range.

Right......that is why I never said all //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif But my point was, if you don't set the switching high enough, that it will affect the output of the higher frequencies. Hence the amp is has an effect on the sound....................

Oh really?? If it wasn't a stumper, then every class D amp would be able to play out to 100khz..............remember, amps don't effect the sound...........

It isn't "digital". It's just on/off (1/0), so it "resembles" a digital signal, but it is not digital at all.

Switching frequency basically relates to efficiency via rail voltage and how it is delivered, not really anything on an audible basis.

Switching faster increases the efficiency, allowing the amplifier to increase it's capabilities.

Keep in mind that class D amplifiers were originally not designed to be efficient across the entire frequency band, as their purpose was pretty much specific to subwoofers. They switched at a lower frequency as a result of this, and would begin to distort when people tried to push thier power supply's beyond their capable intended limits. IE: - Misuse.

So there is really nothing about switching frequency that could be considered to have an audible impact on an amplifier, save one possibility, that being misuse.

From that point, I'll still wager that no one on this board could tell the difference between a 400 watt class D amp against a 400 watt class AB amp on the same speaker.

The only difference you would notice is that the class D provides it's output more efficiently.

I am interesting in the opinions from other forum users regarding the amplifier they would most recommend for clarity and sonic purity.I am thinking of putting a system together and have some preferences of my own when it comes to amps. Here's what I now have.

Soundstream Reference Class A 6.0 2-Ch 50x2 RMS

Coustic Amp 268u 4-ch 50x4 RMS

Coustic Amp 360u 2-ch 70x2 RMS

Coustic Amp 162u 2-ch 35x2 RMS

Altec Lansing ALA 552 2-Ch 50x2

I am thinking of substituting the 3 Coustic Amps for a Soundstream Van Gogh 800.5 which is a 5 Channel amp.

Cosutic amps have reputations of being quite powerful but in terms of clarity I am not sure how they stack up against more expensive brands like A/D/S, Soundstream and Xtant. The Coustic amps would be driving Midranges, Mid-Bass and highs respectively as I have them listed. The Altec would be assigned the role of driving a Subwoofer in bridged mode.

Crossing over would be done by a combination of a Cosutic XM5e and a Rockford Symmetry EPX.

Does anyone have any other ideas regarding this configuration?

Thanks.

I'm open to any other ideas.

Somehow this thread was hijacked by some bored mofo's....lets get on topic.....

Have you ran all those amplifiers together before? And what vehicle is this install for?

Running all those a/b's on top of that SS class a will be a crazy tax on your electrical system, dunno if this is a concern- I like the idea of using that SS Vangogh 5 channel, or maybe even a 6ch(PPI) if you'd like to dedicate power to each speaker individually- actually having a better chance of seeing rated power

running more efficiently and less wiring

watt = watt

now wanna talking damping factor , durabilty, hardware , bells and whistles

Don't Forget the Diamond Audio D7 series

Any quality amp basically with a high SN ratio, and a good crossover set up properly will sound very nice and clean.

I just gave my watts a shower using extra SQ conditioner. They're clean now. I now need some SQ fairy dust for their voices so they can sound as clean as their appearence now.

Who has some?
