what do I upgrade?

If this is my setup, I would
look into high current Jeff Rowland amps.
The Wilson speakers do suck a lot of juice.
Definitely a super size power cord will help too.
I would get a nice tube preamp.

Your electrician aint no audiophool. New has nothing to do with it. Seperate lines for analog and digital unencumbered by any other household electric. That is the deal. Then power conditioning and power cords. You're there. Electric Nirvana

Allen, your stereo system isn't even close to it's potential, unless you have dedicated power. The system runs out of steam trying to draw all that power through a small 12 gauge wire--(your in-wall wire). You need at least one dedicated line with bigger gauge wire. 10 gauge for short runs--- Click on my system to see what I did with dedicated A/C . Also, check out www.equitech.com. I got some ideas from them as well.The whole thing should cost you less than $600. It's the most cost effective upgrade that you can do. It's a BIG, noticeable difference!

I just ran dedicated circuits today along with Albert Porter's ports and am so happy. I was replacing 60 year old stuff so I expect an improvement but still find the amount of improvement completely amazing. The heightened palpable quality, real presence and low level detail. I find the midrange fuller and the bass tighter all with a sense of the music being more simple and clean.

I will find out in a few weeks how they really sound after everything has settled down but if they get even better it will be the cheapest tweek ever...

ya think we're trying to tell you something?
