Mods for Avantgarde speakers

I have had Avantgarde Trios for about eight years. They play music with the types of amplifiers that I enjoy, in a way that I like more than other speakers that I have heard. I would like to hear from others that have modified their Avantgarde speakers, what they have done, and with what improvements. Damping, x-overs, cabling, etc. are things that I am interested in.

Time to resurrect this thread and reach out to Duo users who have upgraded the crossover of the Duo Omega. I understand Duomike replaced the Cap and CPC circuit after upgrading to Omega spec but is it a straight replacement, like for like value or is the CPC module adding capacitance parallel to the Mundorf.

has anyone recapped the sub225 amplifier? I’m thinking the existing caps, now 15 yrs old could be getting towards end of life.

any thoughts.

Hi Mjhill,
Capacitor 2.8uf
Inductor 0.68mhy

i used Miflex Copper 600v as the new 250v was not available at the time plus I now bypass with Duelund JDM 0.01uf Sn/Cu cap.
the inductor is Jensen copper foil. 
Unfortunately the big copper cap is too big to go inside the tube so I mounted it externally. I could have built an external box but it just seemed easier for me. Perhaps the smaller 250v cap will go inside the tube.

Big increase in naturalness and frequency extension without glare. 
I also changed the binding posts while I was modding and damped the tubes. For completion sake I installed SR Blue fuses in the subs.
Would have liked to recap the bass amps but a bit beyond my skills.

cheers
