I totally agree and that was my intended point! I bought two pairs for 300 each all working with yellow working caps. I invented 259 and 35 min each to mid xo with almost identical value caps a and resistors. They aren’t worth anymore the 300.00! Some would even shy away as xo not originals. Fort I have a set of original xo but I do not intend to sell either set. I too have mx1, lp1 fully upgraded, and two dq1. In the end I don’t use mx1 or lp1. Ran days of tests and I get what I need from a sub xo on each dq1 set at 80hz. I do power the subs with a300 w Mac 2300 total overkill . My point is the original yellow caps worked fine. Marginal increase in bass reserve using a big can cap. Only hear diff on 1812 cannons.

Mids and highs marginally tamed dn a bit less harsh. But for just pleasing myself, not sure too most users it’s worth the time and costs. They are 300$ a pair. What a steal. You can spend 10k on B&w speakers and the sound again is marginally?better. I have a pair of 802d. I prefer my 300 dq10. I have klipsh corner horns. Better bass rest of tones can’t touch dq10. I have 4 sets of Bozak symphanies and if I want to listen for more then couple hrs, prefer them to any of the above. THEY ARE WORTH 300.09 in whatever u do yo them isn’t changing their value. People asking 500 sit on eBay for month and month. These 300 speakers are a fantastic value. End of my story
