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.

To clarify, the CPC charged cap is part of the new crossover included with the Omega driver upgrade; does not have to be added if you've already done the Omega upgrade, or bought Omega version to begin.
Hi Face,
thanks. It had Mundorfs in before which i suspect are in the ball park of the V-caps in a slightly hyped sound. I'll probably be shot for saying that, but hopefully you understand my point?

I like the Mundorf silver/oil & the silver/ gold in oils even more so, but the Duelund has a naturalness & image density I really like. It has all the detail but without shouting it. I would call it a grown up listen! I am sure the v-cap is excellent too as many swear by them. I have never seen a shoot out between these fine caps.

I have noticed that a mix of caps brings dividens in some equipment. Maybe not so much in a crossover, but I found in my tube amp the mundorfs shoved or preserved detail to make it further down the chain where some duelunds as coupling caps acted as a naturaliser making sense of everything. Best of both worlds I would like to think.
I have the Duo Omega G2. What if I simply remove the bass cabinet from the stand frame and put it on the floor, adjusting it back to time align the tweeter in the bass cabinet with the midrange horn? Has anyone tried that? The tweeter horn will then be totally free from diffracting off the midrange horn. One could also angle with ease. 
Update... As mentioned, I have the Duo Omega G2. The midrange horn is up top with the bass cabinet and tweeter under that, all mounted to the frame.

I settled on removing the holding screws of the bass cabinet, letting it rest on the frame below, and sliding it back about 20 cm to time align the tweeter with the midrange horn voice coils (as far as I could tell). I put some temporary books under the back of the bass cabinet with the front of the bass cabinet resting on the rear frame support.

If you look at the side, the front bottom of the cabinet is about 1 inch in front of the inside vertical side support. I angled the cabinet back with removing a book from the rear of the cabinet. I can just see the top of the bass cabinet when in the sweet spot.

What did I hear? Much better continuity. More smoothness and a natural sound. Before, there was a little bite and hardness, which is now gone. Doing the above also betters the bass timing with the midrange horn. I likewise did not hear any problem with the tweeter diffracting off the midrange horn. In fact, from my listening position, I can see the whole tweeter with space between it and the midrange horn. This mod is also pleasing in appearance.

This is a very easy mod to do. Later, I will experiment with spiking the bass cabinet.
CORRECTION...If you look at the side, the front bottom of the cabinet is JUST EVEN TO THE BACK vertical side support.
