Harsh Sounding High End Audio Playback
Birchman:
Brian, thanks for all of the interesting questions. My hearing is such that I seem to hear distortions that others either miss or just accept. As to my setup all things remain constant. The only thing that is changing is my choice of player app on the Mac. So yes, the problem is a difference in players. On my Marantz I can see very basic information and the display information does not change between players. As no one else who frequents this board seems to be aware of the problem I will just have to content myself with a relatively inexpensive Mac specific player that I recently discovered. The resident player on the Mac is also good but its interface for my type of musical use is cumbersome. I will also continue to play with eq and volume work arounds for the MC. I think it is time for me to get outside and get some fresh air. Thanks.
Birchman:
Something I would like to point out to the developers of JRiver is that this post has had over 2,500 views in just a few days. What might be reasonable to infer here is that my concern and observations might not be entirely random. Just as an additional aside I don't have any way to run graphics as can be found in Audacity for purposes of looking at dynamic range but suspect that if I had such that I could easily demonstrate that JRiver is compressing/or amplifying the top end to where it can be uncomfortable for some. I use the word compressing as discussed in audiophile circles to describe the amplification or stretching of wave lengths. I don't think the problem is in a Mac's conversion to different bit rates as I have never seen such a problem in files that I convert to different formats. I do think that somehow JRiver is somehow compressing the data. Maybe it is something just a simple as how JRiver's internal volume is set. I am not an audio engineer. Also, I don't have the slightest idea of how these programs operate. I only know what I am hearing and I expect more from a program that I have been supporting for awhile. Signing off. Thanks everyone.

I don't know if you ever took a look at the Weird Problems link in my signature. It would be worth spending a few minutes on it. It might help you reconsider the conclusions you've made. There are lots of ways things can go wrong. All of those in the thread turned out to be unrelated to JRiver. Drivers, etc.
Birchman:
I am using a Mac straight out of the box with no modifications.

I also asked if you could try a different DAC. That test might give us clues to finding an answer for you.
