Lumin X1 and Upgraded DC umbilical cord for power supply.

Ozzy:

What do you think of the AS umbilical after 150 hours?  I really like my X1 and wonder if it's worthwhile to upgrade from Purple to Master fuse, and replace the stock umbilical with AS or Westminster.

Btw, have you consider fiber optic cabling instead of copper ethernet?  It's a significant upgrade (especially for a longer connection from server to the X1).

mtseymour,

First off, I have been using fiber to my Lumin X1 for a long time. Pretty big uptick in sound quality over the ethernet cable.

The SR Master fuse also was a pretty good upgrade over the purple.

The dc power cord with the AS umbilical cable was an ok upgrade. Certainly not to the level of the other 2 I just mentioned. I doubt if the Westminister version would be much better, but boy is that one expensive!

I'll have to try the Master fuse.  My X1 is sitting on Arya RevOPod footers and sound pretty good.

I've heard mixed reviews about the value of the Westminster DC cable.  The fellow who sold me the X1 said that the Westminster was not a significant upgrade (and he sold it separately).  I guess that it depends on system synergy.

At present, I only have a Lumin T2, But I did upgrade to an SBooster power supply and after about a year I upgraded the stock fuse to a Synergistic Master fuse. I ran it for about 200 hours for break-in and then I flipped it the other direction. Then I heard the sound I was hoping for. The soundstage was much improved in both separation and depth. 

I am toying with upgrading to the X1. It will indeed get a Master fuse installed. 

The Synergistic Master fuse is directional, and it is not subtle. 50/50 shot and I installed it in the wrong direction in DAC. Destroyed my midrange.  Switched direction and wow. Highly recommend.  
 

No, I do not have a scientific explanation.  Sometime trial and error is the best approach. Ask the pharmaceutical companies.
