Lumin X1 Review

Generally with Lumin products, use XLR if possible, unless you find RCA to sound better, or you need a lower gain.
 
Jmusica was correct. I replaced the SFP modules and X1 is now working again on fiber. My SFPs probably got 6 months of use before they died. Very flimsy.

Even the expensive SFPs have an unusually high failure rate.

Was referring to (expensive) SFPs used in mission critical computer equipment in large datacenters. For audio purposes there are lengthy threads to be found with some very boring reading about the benefits of one or the other. Finisar seems to be popular. That's what I bought. Whether it sounds better, lasts longer.... no idea really. I don't think I'd be able to distinguish between those and the GTEK I had before them, tbh.
 
Does anyone have a good idea on getting rid of "glare" at around 2-4 kHz? It shows up in some vocals, particularly female. I don't know if this is an equipment issue or room treatment issue?

What’s the rest of the gear look like? Without spending any money, can you reposition your speakers?

When I had my X1, I found it sounded smoother and more even when I left it powered on or after it had been on an hour or two. From a cold start, I thought I perceived something similar to what you describe.
 
Here is my system: ER>X1>Benchmark pre/amp>Sound Lab M545 speakers. I leave my system turned on 24/7. I just got a PS Audio P15 power regenerator and it solved most of my glare problem and sounds great. I probably need to increase the room treatment, but I am happy.
