Jolida Foz SS-X Tube buffer & soundstage expander?


Anyone have any hands-on experience with the Jolida Foz SS-X Tube buffer & soundstage expander?
I've read a few reviews but I want to hear from members of this website that have actually used it.
Your positive and/or negative comments would be appreciated.

Hi lak,

I  received my ssx about a week ago. I am very happy with my purchase. I have placed the ssx between my pre and amp. Directstream dac/anthem d2/ssx/amp thru Triton one speakers.

The overall sound was warmer and shaved a bit of glare on harsh notes. Furthermore there was more detail! The bass was also improved. I am running the bass knob at 0 and the expander knob just shy of 1 o’clock; overall a substantial improvement!

I was was worried that the ssx was just a band aid but I have found no negative. My system already sounded great with a huge sound stage.  I borrowed my friends ssx just to hear it due to my curiosity. I now own one!

Hope that helps
@warr, Thank you for that information, I really appreciate it. That's exactly what I wanted to know.
Best regards...

I just read this review this past weekend and became very intrigued. So intrigued I purchased today.  Seems to me its a very inexpensive sound stage/bass tweak for those of us....audio purists please don't hate me... that live and die by tone-bass-treble -loudness-low cut-knobs. And these knobs, thankfully, are still found out there (ie:Luxman) to personalize our sound.  My room is a non ideal 9 ft high - 13 wide by 20 long rectangle of potential acoustic issues. ( Yes -I have treatments) I'll take a potentially widened sound stage and warmer sound anyway I can get it!
If folks swear by interconnects-speaker cable-and other factors influencing their tone and sound field depth then why not this little unit? 
IN fact, I'm amazed no one has thought of it before.

BTW: I run TIDAL MQA via pc coax to Marantz NA7004 DAC feeding Parasound 2100 new classic preamplifier into either Parasound A21 SS or a Prima Luna Prologue 5.
I have Tekton Lore and Zu Omen DW towers that both bring immediacy to songs sometimes I wish to warm up. I am planning on running this Jolida Foz between pre and the amp. I will report back what I hear.  Who knows, if this works, maybe it could be added into future preamps or integrateds?
