Audience Au24se vs Au24sx cables

Where are ya? sunnyjim-

I hope some of you are still following this thread.  I currently own the Audience Au24e speaker cables...and have a few options that I'd like to ask your opinion on....I can upgrade to the Au24SE for about $350 US (I'm in Canada...so add on another 35% YIKES!)....or I can trade in my existing cables and pay approximately another $2000 US for the Au24SX.   It is worth the upgrade having not heard the XS?   Another option would be to try the Tellurium Ultra Black II speaker cable that would be approximately $1600 US.  I would then get the funds from selling my current Au24e's.  Any advice would be helpful....I'm getting PMC Fact8 speakers....Aesthetix Altas amp with Calypso preamp if that helps.....

@calgarian5355   Upgrade to the SX, if you are staying with Audience. 

Tellurium is well reviewed. I do not have personal experience with their products.

I am using the Au24SX speaker cables with my  6-month old Magico A3's, and the  AU24SX XLR IC's running from my VTL 7.5 iii preamp to Krell FPB 300cx power amp. It took a while for everything to burn in and settle down (especially the speakers) but I looked up the other day and said, O my, but this system sounds extra fine, much better than it ever did!
I have and have had most of the big name cables but the Audience cables do nothing wrong and most things right, without drawing attention to themselves. Easy to live with.
