I have the B@W Martrix 800 I replaced all of the stock jumpers (3 sets per speaker) with High Fidelity level 2 jumpers and improved the sound greatly. Before that i changed the stock jumpers for some older Transparent Ref. XL jumpers and only in the mid and tweeter did i get a small bump improvement. But with the High Fidelity level 2 jumpers it was a very good improvement across the board. Base was tighter mids and highs where much more detail, but relaxed sounding no hard edge.
Room treatments are a big plus too.
