Over the years, I've looked at A LOT of receive audio passbands, but nothing has come close in terms of ruler flatness and bass/treble extension to my 6500.  For your enjoyment, the 6500 USB receive audio passband at 4KHz bandwidth: (click on the image below to see it full size)

I have a Sonos audio system set up in the house and pipe the output of my 6500 to all the units in every room in the house. The audio is so beautiful, I have to periodically get treated for goose bumps.

Yes, she doesn't want my chronic problem of goose bumps to persist.

Thanks for the complement, Barry.  

In case you are interested, this is what the two-tone, in-band IMD and harmonic distortion looks like on an audio spectrum analyzer.
