is there a best music player on the computer?

Danoroo - I respectfully disagree. Have you tried Jplayer? I'd suggest those that are skeptical download the free trial software and judge based on your own ears. If you don't think it improves the sound in your system - don't buy the full program. No harm, no foul.

What is different about JPlay's design is that the program is designed to minimize your computer's hardware and software interruptions when using the music player.

The nice thing about evaluating music players is that all of us can do it via free trial software. Over the last few days I compared players from mediamonkey,JRiver and JPlay. I had no vested interest in the outcome and clearly preferred JPlay.

I have had the trial version of JPlay downloaded for a couple of weeks. I use a Win 7 64 bit, 6gb ram, I run foobar and Jplay. Before JPlay, I had my Laptop as optimized as I could, shutting down all non pertinent software. At first I had a problem with it running slow and distorted most of the time. I was outputting Wasapi, once I switched to Kernal streaming, most problems ended. When I play Hi Res files, if the buffer is set too low, it will still sound distorted, but I can usually just up the buffer and it plays fine. If I understand JPlay, It pulls the files out of foobar, Jriver, etc and in hybernation mode, bypasses all functions and runs completely off of ram. I still get very good performance out of Hybernation mode, but you can hear the difference going to Hybernation.
I would relate the sound quality difference of using a good 14 gauge copper lamp cord as speaker cable to upgrading to a top quality cable. Tighter, more focused, more detail... you got it.

JPLAY for me too,

I don't have any experience on apple side, but if you're running pc with vista or 7, you have to try jplay.

The sound is better in windows 8 actually...
