Grinnell, Tubegroover....
Nice to read your words on the DCaps. I have been off line for a while due to medical issues, so tonight I decided to read up on some of the old threads. I actually thought that this was one of them.
I changed out my old tweeters on my DCaps a couple of months ago. They are quite well broke in. You can count on a hefty month of steady listening to get these tweeters to perform to their fullest. Even now I'm hearing slight improvements almost day to day.
Mods are mods and then there are "the" mods. Back in the Middle Ages, when Dhalquists (did I get that right ?) walked the earth, all knowledgable, and pure Audiophiles would always look for the Yellow Sea of capacitors bedded down under the black mesh behind the drivers. Without that clear bag of CD caps installed ... you were lower than dirt itself, a no- body that knew nothing. Someone to be spit upon, publicly laughed at and always ignored in any audio circle. Some would rather paint them than face the agony. Grinnell, you may be facing that same scorn. I'm sure you have already faced that destiny, laying in bed, feeling the cold sweat turning your pillow into what feels like a wet sea otter.
Happier days and dry pillows are ahead for you. All that you have to do is change the tweeters and you will have the respect and admiration of all that live hear in the forbidden city of musical fools. Plus you will have the added pleasure of hearing what I consider, one of the best musical transducers on earth. We, the ones that have the mod, and are advancing our systems accordingly not only support the investment, but look at it as a no- option scenario. It takes what was already a world class performer ( read duh reviews) and places this wonderful speaker in the ranks along with the very best.... At any price. I will put the presentation of the DeCapo/be up against any speaker at any time... given that the room size is of correct dimensions. I agree with Tubegroover that the tweeter should come first. Even before break- in the soundstage will roll you over in your chair and the brushes hitting the cymbals will mesmerize you.
You have knowing, or unknowingly been going in a good direction for the DeCapo/be. With your fine triodes and silver connections, the spread and efficiency will not go unnoticed with the new tweets. You can tailor them in other ways as well.. With even completely different cable and amp combinations. They will be your personal camialions to color your sound, without loss of musical presentation.
I would do the tweeters while they still offer the change out program. Just my 2 cents"... But 2 cents well worth spending.
