Best $550 I ever Spent Mod your speakers

I just had my local tech modify my B&W Matrix 804's and put in Mundorf Silver in Oil caps in my midrange and tweeter circuits as well as upgrading my resistors (I dont remember the brand they are long and green)

Anyway this is one of those upgrades where you are just FLOORED! I have not been this stoked on a upgrade in a LONG TIME!!!

I have to say if you like your speakers and they work great in your room check out modifying your crossovers. It went so far its rediculous. I could have gotten the supremes for $150 less but I didnt think I'd regret spending anther $150

Best money spent in a long time!
Oh he also coupled the drivers better and used the same screws they use in Wilson Speakers. The bass section was untouched aside from this and it has really tightened my bass up significantly

Im that stoked I had to post and say man, This is the biggest upgrade I have had since I upgraded from a POS harmon kardon PRE/PRO from the EARLY 90's that was falling apart to a CJ Motif MC-7 (2 Mono Preamps sharing a separate power supply and face plate but individual chassis per channel, It is a forgotten legend that never was marketed in the US)

I have never been this stoked on a upgrade I dont think it pulled the veil right off!
Hello Please tell me exactly what type of screws are these that can have this much effect ?
I sure would appreciate your help thankyou, Paul.
good to know...i am aware that manufacturers like Tidal (super high end) will advertise using Dueland caps on SE editions of their speakers. someday may give this a try...can it be done easily at home if speakers are too big to carry?
