so let me see. everything that's 16/44.1 sounds the same.... NOT!!!!!!
thats like saying every speaker that plays 20-20,000hz sounds the same..... NOT!!!!!!
thats like saying all 4 string basses sound the same.....
in other words, several different electronic companies made ad/da converters that played 16/44.1...... some made high end products
and some made consumer grade products..... they all sounded different!
unless the same company were mfg the ad/da converters for everyone, i have know reason to believe that they sounded the same.... well they didnt to my ears....
Not exactly the same, but so close to being the same that it's a moot point.
Some time ago we had a comparison of samplers, and ran the same drum loops through them.
One of the forum members compared several of his samplers, and yes there was differences, but telling the source file from the mpc2000xl was not night, and day, and it did not favor the mpc if my memory serves me correct.
The s900 actually sounded more clean in mono than the 2kxl did.
I thought my Zoom sampletrak sounded better than all of those tested, but my signal chain was different too, so there are many factors.
In the end unless your after lofi, your sampler is a moot point in your resulting sound.
Lo-fi does not include any 16 bit 44.1khz sampler.
My old s900 had to go below 30khz to get anywhere near lo-fi.
My Sampletrak sounds nice, and gritty at 16khz, but not to much so at 32khz.
Your going to have to use lower samplerates for good lo-fi results.
It can be done very, very well with software too, but knowing what an actual vintage sampler sounds like is more than half the battle.
