Wow, just had my Mission 753 upgrades of crossover and also tweeters. What a difference it’s made! The high frequencies are more refined and OMG, the separation and richness of mud and bass if awesome…..much thanks to Willy’s for giving my 753’s a new life 😀😀
Excellent advice from will as usual and exactly what I wanted. These have improved the sound of my current speakers and taken them to another level. Sounds superb I can hear tonal difference's between things that I never heard before. Superb bass drivers dig so deep.
As usual will has been outstanding.
Brilliant to deal with always helpful and gives great service.
What a brilliant capacitor, from first listen exceptional clarity and depth. Bargain will be buying more.
Swapped out the 30 yr old AlCap capacitors for the Audyn Q4 on Wills recommendation (along with a ferrofluid change). What a difference, added so much more definition and clarity. Very impressed. Audyns are a fair bit bigger size wise but fitted easily enough on the board and the access aperture on the TDL Studio 1's.
Good quality, fast postage, perfect! Thanks
