I was wondering whether anyone has got some 'best upgrades' they have made to their systems to share?

For instance, I just bought some soundcare superspikes to replace the standard spikes on my DSP5K's, and the soundcare 'feet for electronics' to support my G98. smile Wow, what a difference in soundstage depth, and low frequency control.

I also replaced my 3 seater couch (which sits between my speakers) with a 2 at the same time. So not sure how much of the improvement is attributed to which upgrade, spikes or couch smile
