Well my experience with HK refurbs is not too good, these were bought directly from HK.
This was about 6-7 years ago, got one there was something wrong with it, sent it back got another, and that one also had a glaring problem with the sound. It was like they just reboxed them and sent them off without any checking for defects. Anyhow finally became disgusted and bought a new Yamaha V1400,which functioned perfectly. Now it has been upgraded to an A1010, which I really like.
I did have good luck with refurbed JBL speakers though, still going strong.
