HD meaning 24-bit and 48/88/96/192 kHz sampling rates
CD meaning 16-bit and 44 kHz
I purchased 2CELLOS's In2ition album from HDTracks.com and it's a 24/48 album.
I downloaded the same album in CD quality just for testing's sake and it has EAC accurate rip information.

- Windows 7 64-bit via Boot Camp
- Foobar2000 (24-bit WASAPI output)
- ObjectiveDAC (24/96 output set in Windows' Volume Manager, digital volume is set at maximum)

I only did 8 tests because I really felt that I was guessing between the two tracks and doing further tests would have been futile. I genuinely tried to hear a difference between the two files and I simply could not make a definitive difference.
When I get the time later, I'll downsample a few of my HD Tracks purchases to CD quality and post my logs here.
Can you guys hear a difference?
- If the answer is yes, please post an ABX log in a spoiler tag
- If the answer is no, why do audiophiles bother to purchase these expensive HD albums?
