PS Direct Stream Vs. Lumin X 1 Sound quality difference?

I also prefer the ethernet input to the fibre optic cable, which I find a little artificial sounding. I use an Uptone etherRegen with a DH Labs ethernet cable which I found did make an improvement. And I also prefer native file resolution - no upsampling

I have a similar setup, I have an ER before the X1 too.
What kind of SFP’s did you try?

First I had Planet single mode SFP modules in them and that was really worse than the Ethernet from the B-side of the ER. After that I tried StarTech multi mode SFP’s recommended by Peter Lie from Lumin, and that sounds even better than the LAN from the ER...it’s hard to believe but these modules really sound different.
BTW, it is very promising that it is still improving after 9 month, mine is about 1 month old now.

Note sure what the SFPs were - whatever I could find at my local computer store. I might have to try different SFPs, though at the moment I'm very happy with the X1 and don't really want to mess with it.
I have generally found that ESS based DACs take a long time to run in - but usually weeks not months! I suspect it is the output transformer which is the major difference with the X1 and which takes a long time to burn in.

While I have owned the X1 I have also compared it periodically to my Mytek Manhattan II (also a great DAC). At first - during the first month - I preferred the Mytek. The X1 sounded rather two dimensional and muddled, with rolled off highs. Over time the highs extended, the bass extended and tightened, and the sound stage moved back further and further. The delta with the Mytek became greater and greater. Recently I did the comparison again and the X1 has moved further ahead, with the kind of holographic presentation and sense of realism and presence that it barely hinted at during the first month or two.

Ingresa tu texto ...It improves even more! Mine has about 400 hours and I am impressed, I have it connected by fiber with a melco s100 sfp multimode switch. This afternoon a colleague also has the melco s100 and he has brought it home to test, we have connected everything in series by fiber. !AWESOME! I'm going to ruin

So are you guys saying that using a fiber connection is better than ethernet?

Let Mecani answer but I’ll add that fiber is thought to be the best connection on some other well known audio forums. Explained there in lots of technical detail as well. No personal experience so just passing along. But it’s yet another thing to learn and spend on if you’re up to it.
