Jolida Foz SS-X Tube buffer & soundstage expander?

Newbee, is your SS-X unit broken in?

You are probably paying attention to quality cabling and vibration control?
I have found this unit to respond well to anti-static liquid
and treatment with a Walker Talisman...

Have you ecxperimented with minor changes to speaker placement
now that you have a new variable in your system?

Will you consider upgrading the fuse?

Far too soon to do or even think about any of that stuff - unit is not fully broken in nor is my understanding of its sound and use. I'm just having fun tinkering with it.

I find the 20hz bass boost to be helpful and the image widening to be great for me, as in my office setup the speakers need to be a little closer together than would be optimal. One minor issue is that with my 91db-efficient speakers, I do hear an audible pop when switching the unit off. I do not judge this to be bad enough to be worrisome but it is definitely there. Easily remedied by turning the power amp off first.

How does this Jolida compare to Schiit Loki? 

It doesn't. The Loki has 4 bands for tone control. The Foz only one (bass). The Foz has a phase control which can affect the soundstage quite a bit. The Loki does not. The Foz has a tube buffer, the Loki does not. The Foz adds a bit of warmth to the overall tone (great if you want it). The Loki is fairly neutral when bypassed. The only thing that is duplicated is the bass tone control.
