[quote=Amfibius]If the James Randi foundation was prepared to pay for my flight over to the U.S to test me then i'm all ears (bad pun not intended). A quick google of James Randi shows that he is out to test paranormal claims, like water divining and telekinesis and so on. Doing a quick search of his site shows that he has indeed debunked claims of special CD tweaks in the past, but nowhere has he made a claim that CD players do not sound different. Especially a $200 and a $2000 CD player. Maybe I missed it - if so, would you be kind enough to link me?
I doubt he pays travel for anyone but he has an email for that Q :D
Same for testing CD players. He was in negotiations to test the Quantum Dot tweak but the subject made too many excuses.I am simply telling you that your assertion that there is no difference between a $200 and a $2000 CD player is false.
Well, it may be false as it would depend on the CD players you are comparing, right?
But, T$$ that is The $ensible$ound tested, DBT, an $80 RCA carousel player against a number of CD players costing $1000s. Yep, no audible differences from a number of test subject.CD Player Comparison, The Sensible Sound, # 75, Jun/Jul 1999.
CD Player Comparison, The Sensible Sound, # 74, Apr/May 1999.
So, in this case, the CD player was even less than $200 against much more expensive ones.
By the way, what does price has to do with audibility???
Oh, some other CD DBT of the past:Masters, Ian G 'Do All CD Players Sound the Same?' Stereo review, Jan 1986, pg 50-57.
Pholmann, Ken C. '6 Top CD Players: Can You Hear the Difference?' Stereo Review, Dec 1988, pg 76-84.
Phollmann, Ken C. 'The New CD Players: Can You Hear the Difference?' Stereo Review, Oct 1990, pg 60-67.I dont think I am making an argumentum ad populum (simply because a lot of people believe in a proposition does not make it true) because time and time again, people have demonstrated that CD players DO make a difference.
How so? Where is that evidence? Citations please?
Or, just anecdotes and testimonials???
Again, some recent CD/DAC DBT's from Spain. Use google translator:http://www.matrixhifi.com/pruebasciegas.htmJust to amuse you, later tonight I will compare my $5000 CD player (Cary Audio CD-306) with my $300 Toshiba DVD player. I have them both set up to run into my preamp and it's just a matter of level matching (which I can do, since I have a CD of pink noise and an SPL meter) and getting my wife to switch the preamp inputs for me. I have identical CD's which I can load into both players. I'll bet you that I will get it correct 100% of the time.
Sorry, that will not do to level match. You need a sine wave and a good volt meter to measure voltage at speaker terminals. Voltage of the two players measure to 1% would yield .1 dB spl, th eneeded level matching. And at 100Hz, 1000Hz, and 10kHz if your meter can do that. SPL meter and pink noise will no do.
And, getting it 100% correct should indicate that there is something wrong with your setup.
Are these two cd players running simultaneously? Or, just listen to segments on one then the same segment on the other? If you are switching between the two while they are both running has a major flaw unless you are able to sync it to 1ms, next to impossible.
Is she in the room as well? If so, that in itself is biasing and has no meaning.
