I've been powering up my Geek Pulse X 24/7 with LPS, anyone did the same ?
It does get warm somehow :)


I run my Infinity off the LPS4 24/7. It sounds great. Yes, it gets quite warm but I don't think it is something to worry about.

What has been people's experience with how long it takes for the Xfi to warm up enough for the femto filter mode to finally kick in and do its thing?  Cause I just had an experience this evening when I turned on FTM mode.  And it took a couple of days of 24/7 on time.  The Xfi is transformed into something really amazing once FTM mode kicks in (you'll hear it when it happens).  Does it really take 3 or 4 days of on time before this magic kicks in?

It's about the same time for me... Around 50hrs burn-in time.

  For me it was about 50 hours. It sounded very good almost right away, but when the Femto's warmed up and unwound, the sound was as I have described, real, focused, natural...so musical.

x2. exactly my experience. X Fi sounds stunning and a true giant killer. I know, we've heard that for every other FOTM DAC around, but the X Fi truly is quite special

I got my LPS coming tomorrow. I also have a little treat (modded headphones) coming today that I will show you guys tonight when I have a chance to listen to them. 
 
I plan to burn in my X Fi, LPS(does it burn in?) and headphones while I am away this weekend.

50 hours for the femto to hit its stride?  That's going to make it difficult to demo at meets.  I'll need a battery pack to keep it running and warm while driving it to the meet.  
 
FTM mode (once warmed up) is where the magic is.  Especially when using it with an amp like the Liquid Fire.  The LF makes the magic even more noticeable compared to the internal Xfi amp.  Before the FTM mode kicked in I was having doubts about the Xfi.  Thinking it probably wasn't going to work out for me.  But now I'm feeling much better.  Very much better.  I scored myself a pretty special DAC.

Maybe 50 hours is the sweet spot, maybe not. I had mine running for 2 days before I switched to it. I don't think it takes that long though if you just want it running at thermal equilibrium. I believe Larry said it takes around 4 hours for them to warm up but it doesn't sound too bad before then.

I was (and I think WE were) talking about 50 hours of BURN-IN TIME to open things up.
 
LH said that Femtos need at least 30 min. to kick in its thing.

While I'm waiting for this to arrive, let's talk filters.
 
I hear a lot of appreciation for the FTM filter. Did people prefer FTM even before the ~50-hour break-in/warm-up period is complete? Obviously assuming you have the femto clocks.

I like the Femto a lot, too.. and find SSM is legitimately well suited for streaming Tidal, Spotify, GPAA, etc.  I think my unit's still conditioning/breaking in.. I'm probably around the 50 hr mark.. amp section still sounds a little more compressed than I'd expected (even w/ using the balanced jack for the HD650)  As far as warm up, I find the X Infinity sounds good after 30-45 minutes.. and is great after at least two hours of continuous up time.
