Avalon Ascendent best matching speaker cable?

In the process of finding the best cable for my speakers I have the feeling I lost it a bit....
Second problem is that I need at least 12feet preferably 14feet (3.5M)
Than budget is factor as well I was thinking around 1225 at 2250$ (2000€)
Of course how closer I stay to the bodes limit how more I will think about upgrading I guess.....

I tested a few
cables already in order of my preference this would be

Siltech 330l
(but with the length I need this would be slightly out of the budget an I'm thinking it might be better to go cheaper now an go to 770l later)

Transparent Music wave super
Connected now so most fresh in my memory but feels like they loosing it in the low sometimes but it gets better by the day or maybe I get just used to theme. An I like there upgrade politic

Purist audio design Aquius Aurius (I think)
superb cables but have to go to an other dealer so don't have the same conditions an they take ages to deliver here in Belgium when you order

ah dls 10
provably the best cable on the market for the price ex 4m costing around 500$

Siltech 220l
once you heard the 330l there is nothing to say

Kimber select 3033
Can't say it's a bad cable but but have the feeling my system lost his agility an freshness.. An they are really expensive even if I got my hand o some 12 feet ex demo

Vertere Pulse x
Being the less good I heard in my system it was like it was all coming from behind a curtain

I'm also still waiting to try out Kimber 12ct, MIT matrix 18 (my dealer newly stock theme), an some Audioquest Gibraltar who where connected when I demoed my speakers so I'm thinking there is a reason I was seduced by theme it was a great match.

I see there are a few Avalon speaker owners so any advice an experience is Welkom

Thanks
