B&W Matrix 802s3 Xover upgrade

Get the NC's and Sound Anchor stands(upgrade the footers and use BDR squares/pits betweren the stand/footers for further isolation).

The cabinet and midrange encloses will respond to Microsan vibration plates placed at the rear.

They are on dedicated soundanchor stands and bi wired Im looking for more than a tweak

The problem is changing for better parts may not always give you a better sound. The crossover is designed with all the parts contributing to give the sound the designer intended. If you change one the balance is changed and you have to know what to do to restore it. That is if you want the kind of sound you have now, just better. Don't underestimate the improvement you can get by "tweaks". Changing the internal wiring on my Spendor S 100s to the same type as my main cables [Cardas] gave a considerable improvement without altering the "voicing" of the speaker. I contemplated both going through the existing crossover and going to active drive but decided the problems were more than I wanted to deal with.

Im not going to spend $2,200 on NC crossovers for spkrs worth under $2K this upgrade will be about $400

If you're in doubt, get the Nautilus. Swapping parts will still cost you and the basic price won't include labor( dyi?). The NC's are more than tweaks as the the Krell, Anodyne and JPS Golden Flute alignment filters. Let us know how much you saved.
