Best free upgrade?

 

The thread starts: About 5 years ago I inherited a pair of two year old Tannoy Kensingtons. At that time I had a Theta CD transport and DAC, Naim 52 into biamped 250s. I tried the Tannoys with and without their speaker grills and their was a modest improvement without them. I now have an Acoustic Precision Eikos, Tom Evans Vibe/Pulse and a Hovland Radia, with much more expensive interconnects and speaker cables. I had been using the grills for safety reasons. I tried removing the grills again, and it was like listening to a different speaker. The clarity and soundstage were very much better. Just shows that things change as your system changes.
