I have constructed a blindest between 3 different sample rates. The original file was 24bit 96KS/s and the worst of my files is 44.1KS/s. Please tell your result from blind testing if you have done multiple independent listenings.

The names is of course random. The bitrate is also somehow random since i might have added noise to some files in order to increase the bitrate and make cheating harder. Please do not tell which file is which if you have cheated using suitable program, send a PM if you have questions of any kind.

Link to the songs http://www.metal-archives.com/album...ndylions/Frozen_Dandylions_-_Overgrown/365406 i used "untitled" and editet out 75% of the song for several reasons.

To me F sounds best and E sounds worst, and D is somewhere in between.
The difference is so close that I'm not sure if I'm imagining a difference or not. Maybe they are all the same! But my ears are telling me F is best. LOL

Do I get a cookie yet?

That said, my ears aren't the greatest (to say the least), and they ain't getting any better with age neither...

All of them sound pretty-bad until the 3 minute mark, that is for SURE...

Guys, to really make a valid comparison you need to be absolutely sure that your system processes hi-rez signals. Certain AVRs/AVPs down-sample the original hi-rez signal to 48 kHz before further processing it.

Here's an interesting article from hometheaterhifi.com with measurements on the subject.

Good point, but I don't use an AVR or AVP for specifically that reason, too much self-noise (that I can hear).

I use a 2-ch DAC and a 2-ch analog pre. I'm really anal about my sound quality like that.
I am using the 2-ch ESS Sabre Reference DAC into a 2-ch XSP-1 Reference analog headphone pre and then into my Sennheiser cans.
The Sennheiser's are rated for 30khz, the XSP-1 and Sabre are both AP rated for 192kHz.

The limit is my aging human ears, not system, I'm 100% sure of that...

Heard no difference except some rare occasional volume discrepancy between clips at some locations. Allthough I run 16b 48khz because I've done 24b 192khz A/B comparison with 16b 48khz and heard no difference.
