The power tubes (large in back) are unaffected by the jumper settings.

so the russian 6n6p should be supported by the MkII ?

Ow yes, and they represent a substantial sound improvement on the lower end and the sound stage as a whole. The bass will extend lower and get a little tighter, which is a nice improvement. Some have said the sound stage takes on a more "realistic" properties, and I agree with them on this.

Just don't forget that most NOS tubes, drivers and powers, will need at least 45 hours of maturing, before they are totally stable. The end result is almost always way better than the start.

Good to know...i purchased a pair of tham, probably are used not nos...they're already burned-in

I've also ordered 4 6j1p as driver tubes to try...which should sound good...i'll compare them to the mullard Ef95s...as soon as i get the damn amp i'm waiting for, of course...

Check out the Mullard M8100.

When I had my MKII, I quite liked the Mullard M8161 / CV40152 with the stock power tubes. I understand, though, that the power tube may make a 15% change in the sound signature of the amp, so consider changing these out if you really get into tube rolling.

It's also a good idea to keep a pair of power tubes handy since they do tend to fail after a year or two of regular use.

I got my MkII this morning...first impressions with stock tubes, just a couple of thoughts...

Ms1 : virtually no improvement over the output of my audiotrak prodigy, which is already strong enough for low impedance phones, with the ld2 lacks some bass impact, probably due to it being new...

Dt-990 : here it comes, sensible improvement over the prodigy even with the unit stock and not burned in, alot more control in the bass region, less boomy, more impactful bass...HUGE improvement over my crappy stereo receiver in my vinyl rig...i realized that much of the hiss i heared was due to that damn thing not the vinyls...it's a compact stereo with broken cassette reader, hissing on the headphone out, radio not working anymore....i'm going to get rid of it

Build quality is awesome, considering its cost....overall i'm absolutely satisfied even at a first listen...i wonder how good it sounds with better and burned in tubes....

After a small lsitening session this afternood i found that the dt-990 , which i didn't like at the beginning when powered from my prodigy, turned out to be very good, better than the Ms1s for some kind of music, classical and synphonic/progressive rock, far more detailed than the ms1...but...still they lack something, especially when music gets faster and louder...that kind of magic grado sound, vocals still sound thin on the 990...it is not their fault...i simply love the grado sound for heavy music....i really have to buy a pair of 325...hoping to have the detail of the 990 combined with the grado sound

The bass will start getting a lot better in a few hours, Meliboeus. Deeper, tighter, and punchier.

I am the proud owner of a ld mk2 thanks to this excellent review and have even got into tube roiling.

Already changed the back tubes for the recommended russ tubes
still looking for a killer set of front tubes

 

[Palantiri7]

Congrats man! I bought one after Penchum's review too, and the amp sounds very good even with stock tubes. It synergises well with my K701s.

I liked how the EF92 6CQ6 driver tubes sound in the MKII. Even though you have to put the jumpers on for EF92 mode, it is worth it. They have that famous "Mullard" sound, which works well for most types of music.

on a side note I use the akg k-141 cans but want to up grade to hd650 or 770-80 looking for a deal now on e-bay.
