I think I'll stick with the MKII, since it'll provide a more warmer sound and the supposedly charactical tube sound. I hope they make a great match with my K271s and MS1. Especially since the K271 itself already has great mids and greatly benefits from ampin'

.

And thanks for the answer.

Just ordered my MKII yesterday. Can't wait for it to arrive!

Make sure to try the shielded Mullard M8161 with your MS1 if you can, that combo sounds magical to my ears.

Came in today, initial thoughts when I get home!

Will using phones with a very low impedance cause any damage to it or the amp?

 

[breakfastchef]

Little Tube states the amp can drive from 32-600 ohm loads. I would not recommend using headphones below 32K impedence.Gain is adjustable via dip switches inside the amp with gains of 10, 5, 4 & 3. Setting a lower gain will give you greater range with the volume knob.

I have been browsing through this thread looking for some info about rolling my mkII. I've decided on the EF92 6CQ6 M8161 CV4015 Mullard Tubes. What should I replace the power tubes with ?

 

[Project22a]

iirc all MKII tube rolling questions are supposed to be directed to the MKIII tube rolling thread since they're compatible with the same tubes?

Um, not quite. All three 6H30 types require a Resistor Mod on the MKII's internal board. I put a couple of notations on there as well.

This is where the majority are posting their experiences with different driver tubes. It is true, the MKII, MKIII and MKIV and MKIVse, share the same driver tube possibilities. This is great, because you can get a better idea of what to expect out of each tube posted, no matter which amp the poster was using.

How long does it take for the MK II to 'burn in'? I'm loving the HD580 and LD MK II combo right now, but the highs are too shrill and untamed.

Usually 100 hours, give or take.

I agree with this initial observation. I'm at a little over 50 hours right now and they've matured nicely, however they're still more edgy than I'd like. I'm waiting for that 100 hour mark to come around so I can start rolling.

Penchum: I'm looking for something with smoother highs. I'd like for the low end to be more prominent and robust, however without any extra "punch". I think the mid/mid-bass is fine as it is and I'm not looking for any sort of bloat in that area. I suppose the best way I can describe this is that I'm looking for a more wholesome, organic presentation. Any recommendations? I'll duplicate this post in the MKIII tube rolling thread.
