Now i might actually focus on the cables and interconnects. Is there any difference between runnning single ended input vs balanced, other than volume level? I have to connect either my gsx mini or mj2 via xlr balaned and the other rca single ended. Any thoughts?

Doesn't it make more sense to plug balanced - the amp that you usually pair up with your most power hungry cans?

Well, i also need to connect my gsx mini. but the mini is balanced from start to finish and apparently doesnt lose any sq when single ended input is used. I would like to know the same for the MJ2 if anyone can provide. My LP was the exact same way, the SE input converts to balanced without any loss in sq. Otherwise I m gonna do as you suggested, run the mj2 balanded input while the mini gets the SE.

Just plugged these in for tonight's late night headphone listening session in the Mjolnir 2.

LOL thanks bud. Lucky for me, i have two perfectly functioning kidney that i can let go for @Wes S stash of tubes. One of the members here is sending me his RFT ecc81 tubes so hopefully that should take care of the tube search for now. Wes also mentioned a few of them to keep as backup so My wallet will survive hopefully (although black Friday is coming up).

Balanced all the way with MJ2.

The MJ2 is a different design than the LP. Use the single ended inputs for the mini.

I fear if @Guidostrunk , @Wes S and company hype up tubes for another unicorn type tube amp. Wallets will surely explode!

Just swapped the stock power cable for a pangea AC-14XL power cable and immediately noticed improved clarity in the top end and overall cleaner presentation.

Yep per Wes's suggestion I did that with the Gumby and MJ2 (AC-14XL for Gumby and AC-9 for MJ2) and noticed a difference. As the overall gear gets better you can hear the differences that each upgrade makes in the signal path.

Dumb socket saver question:

Whenever I pull my socket-saver mounted tubes out, the socket saver comes with it.

Which would sort of seem to defeat the purpose.

Does the same happen to you guys?

Oh, please. Cables don't make any difference.

(until they're fully cooked. )

Do you not mean implode?….the $$$ are away…what’s left is leather & bone…

Do any of you guys know if an E288CC will work in the MJ2?

Specs here:

It seems like it should, but perhaps I'm overlooking something.

It is too “hot”. The E288CC filament (heater) current is 475 mA; the 6922 / E88CC filament (heater) current is 300 mA.

Yeah, I just noticed that, too.

I believe the MJ2 requires <400.

Although I thought 6DJ8 was 365 mA

I was watching some interview with Jason Stoddard the other day, and I could swear that he said that the MJ2's high gain is open loop, with less feedback, than low gain.

He seems to say in high gain it sounds more tubey, but in low gain it sounds more neutral.

At about 19:00 mark:



Has anyone else run across this before or know where I can find out more?
