Got my #137 LC on 18 Nov delivered to Singapore.
Always on (whole chain except N6), burn-in with music playing for >200hrs
Cayin N6 -> Coax - > Schiit Gumby -> Balance XLR -> Cavalli Liquid Carbon (Unity Gain) -> DUM XLR -> MrSpeakers Ether
The vocals were a little bright for my taste right out of the box. That tamed over time (most obvious change for me). The rest I can't really describe, except it sounded a little, slightly better ... a little more ... smoother ... a little more ... sucking me in.
All I can say was the I'm loving this setup more and more each day. Most of the time I stop thinking of what setup I have and enjoy the music.
It's very much beyond 150 hours ... so the sound should be stable. Maybe it's just my brains burning in now.
One thing I love about the LC is how well it plays at very low volume. I typically play at 1x gain with the volume pot at 9-10 o'clock.
Sometimes, I listen at 8.30 o'clock and I can still clearly enjoy the whole song ... every nuances and notes clearly. Of course, the room is fairly quiet with doors, windows closed and curtains drawn (aircon on). But I do have a waterfall about 25m away just beyond my windows/curtains.
I have not found the need to go beyond 11 o'clock when using the Ether. If I switch to the Alpha Prime, I'll have to go beyond 12noon to about 1pm. Maybe a little more.
Have not done an A/B with the iFi iCan Micro yet so I don't want to comment on the differences. Now, need to find more time to listen to music
