Do I need a seperate amp?

[MacManNM]

firstly, all ABX are level matched to .1dBspl, for your information. Second, the ABX box switches real fast, better than that. But why switch it when th emusic is running and not stopped? You will forget what you are comparing, regardless how fast you switch, the music changed, not comparable. You need to loop it in 1 second segments to meet your criteria. And, you need to jump on those that claim you need long term listeing, right?

If the two amps FR are not within the .1 dB and exceed the JND and exceeds the badnwidth JND, of course it is audible. So, you are not comparing apples to apples, but hear level difference, nothing more, nothing less. So what?.

So you are saying that if you don't compensate for differences in FR levels they won't sound the same? You just made my point.

Why would you drive a speaker load that an amp cannot drive? That is what you are asking. Silly..

I never said that. I said to use several different speakers with different loads, I never said to exceed the amps capabilities.

Oh, the listening room will not affect amps differently, just the overall acoustic soundfield. But you knew this, right? silly requirement..

No but listening rooms will tend to accentuate different frequencies. This will tend to show the different responses of the amps more radically.

I can hear the difference. Plain & simple. My Axioms have a more balanced & more detailed sound with amps hooked up than just fed by my Yammy 3300. No question about it. If there was no audible difference I wouldn't have wasted any more money buying additional amps.

But the real question is: did you compare biased? Bias controlled? Levels matched? Makes a huge difference as to the quality of the results so, it is not plain and simple in the end

 

[MacManNM]

Yes, exactly. And that will not be audible a sthe 6 dB is not at the same frequency of the other component, unless it so happens that you are comparing two such components and it so happens that at the same frequency it will be 6 dB different. I will accept those statistical probabilities. Like nil. But, you could show me those two that meets the 6 dB difference at the same fr. But you may want to lower that to 16kHz, where the JND is 3dB spl increasing rapidly up.

A delta of 3db is clearly audible.

I am just an audiophyte at this point. I have a new system composed of ;
Paradigm Studio 100 mains,a CC470center,ADP470 rears,and a PW2200 sub .My power is a Denon 3805. This sounds great to my ears and pdg to my wife who has very demanding ears. Will the addition of a seperate amplifier make a great difference if our playing level is at lower medium volume? Our room measures 14x25x8 and is set up like this.

I have tried using my 3805 with a 200 WPC Adcom and a 300 WPC Bryston. I did not hear the hugh difference that 20 to 20K claimed. May be his equipment and room acoustic makes it easier for him to tell the difference. In my case, I have to listen very carefully, and tried hard to listen for the expected improvements in details, and sound stage etc., in order to convince myself that difference in sound quality/characteristics exist between the Denon only, Denon + Adcom and Denon + Bryston. My Veritas speakers have a sensitivity rating of something like 87/88 dB, so they are not too easy, nor too hard to drive. I also had problem convincing other members of my family, and friends, that one combination sounds better, or just different than the others.

So my short answer to your question is, it "difference", but it is unlikely that you will hear the "great difference". By the way, before I decided on the Veritas, I had also auditoned the Studio 100, driven by an high end Anthem separate setup and a Yamaha RX-V2400 receiver. The difference was not "great". By quickly switching the speaker cables from one set up to the other, there appeared to be some differences in details and sound stage, but I would not say I could pick them out in a double blind test. Again, I was with two other persons, they could not hear any significant difference neither.

Please note that I am not participating in the current debate. I am just trying to response to Rich's question, based on my experience with the specific equipment I mentioned.

You should have participated.

Just think, you have these results, and most likely from a sighted comparison. I wonder what would have happened under some bias controls

Any amp/reciever. I would like to see it rated at the maximum wattage.



0.000000001% is to much, we are going for perfection.



Because everything sounds the same right?



Bingo, you are right Buckeyefan 1 these cheap cunts just do not get it or are not hearing it.



You just do not get/hear it do you?

Crap like this is not necessary and won't be tolerated. Privateer gets a 7 day ban for this.
