3000 dollar is pretty ambitious indeed!
In front of the Apogee Scintilla's midrange is a 240 uF cap. Apogee already used multi parallel caps in the mid 80's as they constructed this cap out of 24 x 10 uF polypropylene Sprague caps. The Spragues are nothing special, still the Scintilla's midrange (a 1,5 m tall 2 inch wide pure aluminium foil) is considered by many professional reviewers as one of the best they've ever heard. No doubt the good sound quality is not the result of the Sprague caps, but of the Scintilla's design (ultra-light ribbon, a special magnet array which houses both midrange and tweeters etc.). However, I would not be surprised when it turns out that the relatively cheap Spragues in front of the midribbon don't seem to affect the sound in a disappointing way as the cap is a large multi parallel cap. Maybe when Apogee's had used larger value Spragues (when available), the midrange might have lost some of its quality.
I btw will replace the Spragues by 21 x 10 uF Gold Obbligato's (size: 30x75 mm), the remaining 30 uF will be smaller value Gold Obbligato's.
In my situation size doesn't matter as I've decided to build an external xover which has several advantages (in my situation) as well.
The 10 uF Obbligato's retailprice is 25 dollar and when you order something like 50 pieces, diyhifisupply in Hong Kong will offer a discount of 50 percent. In my case all caps costed me around 700 dollar.
Of course I would have loved to have the Spragues replaced by pure copperfoil PIO caps but for the extra price so many other upgrades in my system could be made. My hope however is that one day the Chinese (Obbligato?) will decide to manufacture pure metal foil PIO's as well...
