Has anyone here had experience in upgrading their standard issue De Capo's to the newer "i" version? can you please also fill me in on its merit , cost, and what kind of improvement was noted?

Thanks

Many have done it on this board and most seemed quite happy with it.  You may want to do a search.

Upgrading De Capo's to De Capo "i"s

Hoping to alleviate the occassional upper-mid/lower treble problems I heard, I did the "upgrade" a couple of years ago. It was a very easy procedure to do, assuming you can use a soldering iron.

FWIW, while deciding whether or not to upgrade, I had a conversation with a skeptical-sounding dealer (can't remember who) who felt that the release of the 'i' series was not to improve the speaker, but rather based on a financial decison by Reference 3a to find a new tweeter-maker due manufacturing difficulties of the old one.

I went for it anyway, but I'm not sure it made a significant difference: I still find the DCs to be amazing on some recordings and awful on others. That said, I am one of the few (the only?) who did not rave about the improvements I heard (in hindsight, I think the $200 would have been better spent on new music). Many others have disagreed, so you'll have to use your own judgment as to whether or not to do the switch.

Since a few of the die-hard De Capos guys around here have sold them of late,  I'm guessing I'm not the only one who has had some ambivalence about them.

Upgrading De Capo's to De Capo "i"s

I'm not sure about the tweeter issue being on the manufacturing side.  I still think they work with Seas to have their tweeters made.  They just stopped using ferrofluid in the tweeters and I think they damped the rear chamber differently...but I'm not entirely sure...

The other differences between the previous de capos and the new "i" version is the cabinet as well as connectors and caps.

I had the standard de capos a while back and was also thinking of the upgrade but never did because I didn't feel it was worth the effort or trouble.  However I picked up Chuck's de capo-i's here on AC for a song so I could own a pair again as a reference (pun fully intended).

I'd say there is a subtle difference between the de capo and the true "i" version because of the better cabinet control but it's hard to say since I dont' have them side by side.  However a friend of mine has the older de capos and we both agree there is something subltly better about the "i" version we just haven't taken the time to do a side by side to figure out what and how much difference there is.



I'd agree with Jonathan on this one to a certain extent.  Is a minor improvement worth the time, effort and money you'll put into it?  That's ultimately up to you.  I do prefer my "i" de capos to my old de capos but they are the redesigned versions, not just the tweeter/cap swap.  

If you do decide to go with the "i" upgrade I would recommend a few further upgrades:
-better binding posts such as the Cardas Copper Binding Posts (short) as they are quite a bit better than the stock brass/gold plated versions.  Might as well do it all once you have the de capos on the operation table...
-damp the side of the cabinet walls with some premixed ready set concrete patch mix available from your local home depot or lowes.  You only need a thin 1/4" layer to damp the sidewalls.  You'll need to get the inside of the cabinet slightly damp so the patch mix adheres better.  I've used this on a subwoofer and it never shook off, cracked or crumbled.
-Three sorbothane pads; two placed under the front of the de capos and one under the rear.  Improvements were immediately heard across the range(cleaner midrange, better highs and bass was still tight with no flabbiness). http://cgi.ebay.com/44-mm-Sorbothane-Isolation-Pads_W0QQitemZ5802149492QQcategoryZ3280QQssPageNameZWDVWQQrdZ1QQcmdZViewItem">Sorbothane Pads/Pucks couple the speakers to the stands at low frequencies but decouple them from the stands at higher frequencies...Gary at PandaThumbAudio better explained it to me one day when I asked to buy his pandafeet for my de capos but he said they would not work...I then told him I was using these pucks and he gave me the explanation as to why they would work perfectly.   Anyway, just try them at the very end of your tweaks so you can hear the difference.

Maybe apples and oranges. However I heard an old pair of L’Integral’s (floorstander) at a store and I preferred the sound of my tweeter (i -version) for its openness and bite. Older tweeter may be a better match with solid state amps. “Horses for different courses” My other reference is a pair of ATC's, which desperately need a muscular ss amp.
