I have received my iFi Audio LAN iSilencer. I will be posting my sonic observations as it burns in.

So far, there is a rather noticeable reduction in digital nasties such as leading edge distortions and ultrasonic hash. The sound is cleaner and clearer, but with a layer of opaqueness that should dissipate with time. I have yet to detect any graininess.

 
It's a little more revealing today, in a raw "this is what it sounds like" sort of way, with no undo fatigue however.

48 hours later, and it may be 2/3 though its coarse burn-in period, as I hear more deeply into the recordings with just a bit of roughness around the edges remaining.

I have found of everything "digital" I have ever owned, none have needed LESS than 200 hours, and many need quite a bit more.

Well, they say that this filter requires 300 hours to reach its absolute best, so that is likely due to the capacitors it employs.

Tonight my ears are a bit fatigued, and I sometimes think I hear a metallic sheen on some of the voices and instruments.

But being that my hearing is somewhat compromised at this point, I am going to say that I can hear a little further into the recordings nonetheless and leave it at that.

I will make further reports at the 100, 200, and 300 hour marks, and whenever I hear a notable transformation.

Or this filter is bringing out the weakness’s of your digital front end.??? May have jumped the shark.

I often find when buying in gear it will go from bad, to good, to bad and back to good during the burn in process. For some reason on many of the pieces I've received the 70-100 mark is usually a step backwards from the 50 hour mark.
 
It has turned a major corner today. It is like when one reviewer said that it all of a sudden just sounded right.

We will just have to see what it does next.
Nice!

While not what you have, this mimics what the Muon Pro did in my system. It was akin to listening to a system on crack, with peaks and valleys, weird stuff going on and everything in-between.

What I did notice is that when you get a glimpse of something good and then it goes away? It came back with a vengence, even better than before. All of the wonky stuff simply went away. It was painful to experience, to say the least.

Sounds like I will have to experience the same thing (or something along those lines) with this unit. Not looking forward to that...

At 200 hours, it has been rough since the last time I reported in.

The main issue is fatigue, with it leaning towards and just hinting at hyper detail.

What will the next 100 hours bring?

Might be time to send it back.

Give it till 300 hours. That is the bare minimum I feel for most gear/cables based on my personal experience.

Some are closer to 200, but most is 300++.

I'll second this. My first SmoothLAN took well over 220 hours (the point at which I got busy and stopped counting) to reach final state. I also experienced some ups and downs, though not as bad as the OP.

Yeah - it's interesting to see the hours units need. I keep a running log of some of them when they really open up and here is a list of just some of the recent pieces I've tried off the top of my head:

Luxman 509x - 275 hours
Luxman 3880 - 275 hours
Aqua La Scala DAC - 600 hours
Tobian speakers: 350 hours
Antipodes Audio K21 & K41: 300 hours
Cables: varies between 250 - 300 hours
VAC 170i Special Edition: 250 hours
Telgartner M12 Premium switch: 300 hours
Klipsch La Scala's: 350 hours
Klipsch Cornwall's: 300 hours
Accuphase E-5000: 250 hours
SoTM gear: 300 hours
Network Acoustics: 300 hours
STEALTH Audio cables: 400 hours
Siltech Cables: 200 hours

AND I have found the digital gear needs time to settle from the jostling of transport as well.
 
Well, it appears I am having a few issues with getting the best sound from my computer.

While the filter is performing better, every technical change to the sound configuration of Linux results in a big change in sound (and not always for the better).

I originally had set sampling rate set at 176.4 with a bitrate set at float32le. But then I weighed the pro's and cons of manipulating the signal, and set it back to its default of 44.1 and s16le.

My WINE driven copy of Foobar sounded terrible, but mainly while streaming, while my copy of Audacious sounds fine. Neither was set to upsample.

Then I tested my reference DSD file through Foobar set at 352.8, and it sounds marketly better, where no amount of (player) upsampling of the digital streams were an improvement in the smoothness of the sound (quite the contrary).

Computers are often too complicated, and getting digital reproduction to be acceptable doesn't seem to be any easier.
