Primaluna EVO 400 vs. stock Cary SLP-05 preamp?


I was considering the Cary Ultimate upgrade ($1600) for my SLP-05 preamp, but never did it. Now upgradeitis has me considering the Primaluna EVO 400 preamp as a replacement. Does anyone think that there would be a noticeable improvement with the EVO 400?

I haven't heard either but reading the web pages I would stick with what you have if you're happy, I imagine the upgrade will even deliver more and it's made in the USA.
Decided on the SLP-05 Ultimate Upgrade. The preamp is on its way to Cary.
 In its place I’m using a Formula 1 modified Cary SLP-98P.  To my ears, the mod’d 98P sounds better than the stock SLP-05. I’ll report on the mod’d 05 after I receive it.
I also vote for the SLP-05.  I owned the 05 as well as the 98 and the o5 was significantly better in my experience.  The fact that your modded 98 was better than a stock 05 is very impressive!  I'm curious to see how the upgraded 05 stacks up.
