Heh, yer brother is messin with you, there are definatly differences in CDP's
Example,
I have 2 sources hooked up, a Denon 2900 and a Pioneer CDR. I keep the CDR mainly for recording and do pretty much all of my listening with the Denon 2900.
He gets off work a couple hours before i do and usually has music playing when i get home.
Before i even open my door i can tell if he is listening to the radio, comcast digital music, the CDR, or the Denon 2900.
The problem with those tests is how many of those audiophools owned the players being tested?
I can tell which source is being played before i even walk into the room because i have had enough time with my system to be able to tell the sonic characteristics of each well enough to make a guess as to which it is with about 90-95% accuracy.
Put me in a room on a system i dont know, with several players of various price points and i wont be able to tell them apart for a while either. And even when i do start hearing and recognizing the sound to A B and C which would probably take days of extended listening, i would need even more days to be able to even ATTEMPT to guess the price tags of the players.
There are differences but they are subtle, and i dont believe anyone will be able to just walk into a strange system and be able to tell which player is which just from listening to them for a few minuits, it took me a few weeks to really pin down the sonic characteristics of the Denon 2900. The radio usually sounds compressed and crappy, the Digital Music is pretty clear but still compressed with a higher noise level, the CDR is pretty good but just lacks the detail of the Denon 2900
Sometimes it takes a little while to get to know the characteristics of a new piece of gear and how much you like it, but you can take a song and play it on my Denon 2900, Pioneer CDR, and 4-5 other players, i wont be able to tell what the other players or thier price points or anything, but then the Denon or Pioneer are playing on my system you bet yer ass that i will know it. Those 2 players on my system are plain as day to me.
I would be willing to say the same thing about any component i have in my system.
I dont know how it is for others, but when i get a new piece of gear and it sounds better, well, it sounds better right off the bat, it just takes me a while of listening to figure out exactly what it is that i was missing before.
that is the problem with the super-triple-threat double-dog-dare Uber-stupid bogus blind tests.
How the hell are you supposed to pin down the sonic characteristics of CDP's on gear you dont know?
as for your brother saying if it cant be measured it doesent exist, that means that we currently have the ability to measure and quantify everything in existance.
So that means that since we havent measured god that must he doesent exist, which basically means there is no afterlife, so he better have fun with the time given to him cause once it is over it is totally over.
better go ahead and tell all the scientists to go ahead and take a break cause we know everything.
