WAV versus FLAC

Aplhifi,

You said "IMO again, Monkey's Audio and Apple Lossless are superior and much closer to uncompressed WAV, but they still lack the top-end information (air) of uncompressed WAV which still sounds best to me. " I do not want an argument but I would test your ears and equipment before speaking about the last bit of air... follow the link and SORRY if it makes you sad....

Test tones from 8khz-22khz

I'm pretty sure you'd be the only one questioning Alex's equipment here.

On the test site you linked, I could hear 18khz but barely 19khz. I don't believe that is accurate as I don't think my hearing is quite that good as my ears have been around for five decades now. On previous tests (not from the site you linked) last year I could otherwise get to 17khz, and no further. So you are suggesting that because we loose some of our ability to hear the highest frequencies as we age that we are also no longer qualified to make judgments about how well as system/component delivers high-end information? That would probably leave the majority of the folks posting here, the majority of the staff at most of the rags (FWIW), as well as many of the most respected manufacturers of high-end gear at a tremendous loss.

Jax,
Yes that is some what my point. If there is a difference in the formats it will be at the extreme highend of the frequency. Not sure many of us really (myself included) here it anyway.

I guess my point is the difference is very small, and our systems (and ears) have much bigger issues.

I know my system does not put out anything above 17khz. With Sennhizer 650 headphones I hear to 19 but on my speakers it is dead after 17khz.

Why is the only difference in formats evident in the high end extremes? I've never heard that before. What are you basing that statement on?

The difference between your speakers and headphones, beyond the obvious limitations of the specific transducers, is one of isolation. Your speakers abilities are profoundly affected by the room, the contents, your seating position, etc. Those factors have no effect on headphones, which have a much greater degree of isolation. That's probably why they don't use speakers to test your hearing.

BTW Sennheiser HD650's are not known for their upper-end extension. In that region between 10-20khz they drop down severely just after 10khz averaging around -15db! At 19khz they are -10db.

Uncompressed is lossless is uncompressed.
