Glad I read through this thread, again. It reminded me to order the ifi NOS tubes. Any comments on them with the mjo2?

Funny that, I posted yesterday I forgot about the order I made a month ago with Music Direct. It arrived this morning, very nicely packaged too, haven't seen anything like this before. 8" x 3 1/2 " x 2" white box with a photo of the tube on the top, info on the tube on the bottom of the box, and shrink wrapped, and it was in a larger cardboard box with plenty of brown paper wadded and padding. Neat!
 
Probably a few weeks before I get around to testing, too much other stuff on my "to do" list between now and the end of Sept.

I haven't heard the Mj2 but I used to own Lyr - and now two Decware tube amps. Without question all 3 can sound vastly different with tube rolling. From posts in this thread, I'd say Mj2 is the same.

Stock tubes rarely show an amp at its best

Indeed Woo tips their hat about that..."here's an overbuilt, overpriced art object that contains an amplifier...but for even more money we can put good tubes in!"

I've used three of the tubes in the 2C51 family, they all perform well in the MJ2.
The 5760, 396A, and 6N3P-E.

Good source for the 5760:

What are you using for an adaptor?

These are good quality; I have a couple pair that are for rolling, testing, comparing; no issues. Matched sets on the burn or in rotation have dedicated adapters, that way the adapters remain very tight on the tube. The adapter will come out with tube when removing the tube from the Schit amps.

I'm very interested in trying out a 396A tube in my MJ2. Reading this listing sounds like the 5760 would be a good alternative. Are these usually matched well? I see he doesn't have a matching service. Just wondering how much of a concern that is.

I think it should probably be fine. Just make sure to get the right adapter.

No that seller for the 5760s is not selling matched tubes, but they are true NOS in original boxes. Really nice tubes. Incredible price.
In the past I have used used some NOS tubes from the same batch without matching, no apparent harm done. After I starting matching tubes, I tested some of the pairs, found some were already well matched, some were within 10%. Obviously if a tube has noise, choose another. If you notice channel imbalance, switch the tubes channel to channel, if the imbalance follows the tube switch then choose another tube. That process was done with my Lyr and Valhalla, the tubes I have used in my MJ2 were matched pairs. I have countless matched pairs so no need to go there with the MJ2.
 
There is a seller currently selling some 396As that have test numbers listed, about $65 each. Yes, the WE 396A is a really fine tube. However, if you cannot find a well matched pair, not to worry, go for the Reflector 6N3P-E, in my opinion this is the better tube. I would rank them RE 6N3P-E > WE 396A > GE JAN 5670W.
 
Let me know if you want the Ebay seller for the 396A. Also, if you want a matched pair of the 5670 and can't find a suitable seller, let me know and I'll send you a matched pair from that seller at the same cost, I'll never use all the ones I have. I think they were $4. Get the adapter first because that will take longer in shipping.

Next dumb question. Does the Reflector require an adapter? If so, is it the same as the 396A?
 
I've seen the listing for those matched 396As I think, but $65 per is a bit out of my budget at the moment (saving for a new 34" ultra wide screen monitor, upgrade for Gungnir and Ether Cs).

Yes, note that the auction includes reference to "6N3" in the title:

However, Note that the tube you want is the 6N3P-E Reflector, there are a few different variations of this tube.

Ahh, I missed that, thank you for your patient instruction. I'm getting there. I ordered the adapters. I'm cautiously shopping for some tubes. I will probably post some ebay listings to ask for advice if that's ok.
 
I really have to get to building something to make turning the MJ2 off and on again easier and a mute box to cut sound off to my studio monitors. Sure wish the MJ2 would mute when headphones are connected. It's honestly my only complaint about this awesome amp.

Hey there, I am in the market for a balanced amp as I'm pretty curious about running the HD800s with their balanced cable.
 
The Mjolnir is an obvious choice as the price is right, and I happen to have some pretty good 6922 tubes hidden away. 
 
I did have the Lyr and I didn't like it much. I found it to have a hot and fuzzy unresolved sound that always made me think I was missing something.
 
So the question I have is where does the Mjolnir 2 lie in regards to the old Lyr? Thanks for any comments as there is no easy way for me to demo the Mjolnir 2 short of ordering one.

Hmm, what if your MJ2 SE output went into a SYS, which you could either switch (to the empty channel) or turn down to zero as necessary? I'm not yet in a place where SYS makes sense, but if I ever get into Vinyl, that will change.

The consensus was to use the balanced outs to my monitors. I need a balanced SYS, you hear that Jason?!?
