Pink Floyd and Weed

@grm  No worries glad to help but you still haven't said, is bass light on everything or just the Floyd.  Anyway, J-River is dead easy. Pick TOOLS from the menu bar, bottom choice OPTIONS.In the main box you have a list, the first choice is Audio Device, second is Settings.  Usually the only choice under Settings is "DSP & output format", choose that. In the new box along the left side is a list of functions ; equalizer, room correction lots of fun tools.  The last one is the Analyzer, select it with a track playing and you see a graph of the sound level/freq.  Don't worry about messing settings up it's a computer app.  If you get way out of whack chose the default preset.  Also you are usually asked if you want to save changes before exit.  The analyzer is just for fun but is very interesting in what it displays. For simple checks involving boosts and cuts just to see what happens the plain old equalizer is the place to start.

russashe,
The bass through my HD600's is light on everything. Through my main speakers everything is fine and it's not just the Floyd recording.

I have printed out your navigation instructions for J-River, I really like the app and what it can do. I'll be trying your suggestions with it right after this post, many thanks!

Hi,
Adjusting the equalizer in J-River did the trick, many thanks! At some point I think I would like to invest in a new headphone amp, with the Quicksilver high on my list.

Happy listening!
