Fiber Optic isolation causing listening fatigue


Just curious if others have experienced the issue I'm having. I have a decently resolving system: Aurender N150>Weiss DAC 204>Wyred4Sound Pre>First Watt J2>Omega RS8 monitors. Not being able to leave well enough alone, in a quest for more detail, I decided to isolate my streamer from the router by dropping in two TP Link fiber media converters separated by a fiber optic cable. Well, initially I got the effect I was hoping for: I heard a great deal more detail in my music. I could hear the singer take a breath where I typically couldn't. I heard nuances of music that typically escaped me. In fact the effect wasn't really subtle. There was much more clear instrumentation separation, etc. However, after about an hour of listening, I started noticing a feel of irrititability, just a general annoyance. I told myself "you're just over-caffinated." But I think the added level of clarity was simply causing listener fatigue.

Anyone else experience this with a fiber optic upgrade? Of course the fiber optic cable will not require break in (it is simply passing light through a channel), but maybe the fiber media converters would need time to settle in? I was trying this upgrade as a "proof of concept" thinking that I would upgrade to a Sonore Optical Module Deluxe if I liked the effect. Now I'm not so sure I'll take the risk in spending more money on this.

I guess I'm just curious if anyone has had this experience. Or might have some thoughts?

Thanks,

What fiber setup did you deploy for Meitner MA3i. Curious because I own this DAC. 

@surlydale It might be that the added detail you can hear is actually just a db boost in the presence region. Typically sounding good demo wise but ultimately fatiguing in the long run? 

I will take a different tack and say that you are now hearing more of your system and the way it sounds. From what I have heard of the Weiss DAC’s, they can be pretty detailed, and coupled with super efficient and fast Omegas might be part of the problem. This is purely conjecture on my part, as I have not actually heard these components. I think if you are hearing more of the music with optical, then there was a problem in the first place, but now maybe the optical components are adding in their own new noise. I have had good results with the Stack Audio Ethernet Regenerator, spendy, but a definite improvement.
