Hi Steve,
I have tried JRiver... a year ago, no jplay. I tried Media Monkey, didn't like it. I have tried JPlay w/foobar 2000. At first I thought Jplay was a miracle, very nice improvement... I got rid of anti virus, I increased ram, I made all my computer settings for the highest performance settings going for Foobar 2000, went into Foobar advanced settings and changed the buffer to handle larger files (I've read this causes files smaller than your buffer settings to play from ram), I deleted a bunch of programs not used and turned off everything that I could... NOW Jplay just didn't matter.... Recently I downloaded Windows 8 and there was yet more improvement. I haven't tried XXHighend. Thanks for responding, Tim
