Testing mine now. Only had it on for like 20 minutes so far. The stock tubes have not had their burn in yet (some people say tubes need at least 100 hrs on them and say the stock tubes are not great) but I can say the stock tubes sound pretty good so far.
First impressions is that the bass is clean and stronger than my little bear b4 (example: song: the weeknd call out my name on youtube has very distorted bass and this amp does it very clean which is good for a low quality youtube video). It does sound spacious which I wonder will change (a bit recessed maybe burn in will help or aftermarket tubes).
I have some ge 5654. Russian power tube and russian voshkods on the way, will test once I burned the stock tubes in first to see how awesome the new tubes are (have to burn them in too cause I got the new versions).
Issues so far: - Mine was shipping by fedex and the box was damaged on the side. Unit is working fine so far tho. - Already known issues: Up to like volume 10 the left channel is louder then once you raise the volume it gets balanced. - With nothing playing you can hear hiss above volume 50. Barely noticeable around volume 30. I hear burn in will fix the hiss or trying higher quality tubes than vs the stock.

Z0d1AcHiss is expected. Especially on stock tubes. This is normal :) Try to min volume of source and max out LD MK II to get out most of tubes - listen to guitars for example Hotel California :)

Thanks for the suggestion. %100 windows volume you can still hear it. I also heard hooking it up to another power strip with nothing else plugged into it could fix the issue and will try that some time later.
I have it hooked up to a computer. New motherboards such as the x370 or z370 have a known issue of channel imbalanced and channel leakage above windows volume %90. So I leave mine on %80 which brings the bit depth from 16 to 15 and is not much of a issue. Or if playing music files from computer (not games or youtube because I don't know how to get audio) then you can use foobar with asio.

Z0d1AcOk sorry for confusion. I cleaned pins and zero hum. Also what you suggested hiss may be caused by motherboard. I'm using external DAC icon hdp. Silence. Nice ;) also have 600 ohm dt-990 for that purpose and gain set to 3 minimum. It's great! It seems what you hear is EMI

Try "The Pizza Tapes" (Jerry Garcia, David Grisman, and Tony Rice) : All guitar and some serious jams.
