I wonder if they would just say "Oh thank God, it's just those lousy GE Stock tubes .... no worries" ....

“Holy cr#p, this aircraft has GE parts in the engines”….….

You mean just a Pelican case? If so, you can find them on Pelican's official website and on Amazon.

Still trying to figure out why a case is needed. Just bring that badboy straight on! Light 'er up!

If Mainline has balanced switch does it mean that I can use balanced output from my DAC to the Mainline with XLR to RCA adapters?

RCAs are non balanced. Also, I'm pretty sure, the whole amp is not balanced, so the only thing using an adapter would do is allow a little more power to the input, XLRs typically have more power on DAC outputs, making the volume a little louder.

If you want to try it I recommend these adapters, they are great. I use them to run from my XLR switcher to the Mainline.

Will I benefit if I run HD8xx of the balanced jack on Mainline vs SE?

It would be a pretty minor improvement running the 8XX on the balanced. Maybe a 2-4% improvement in over all sound separation/clarity. Though running on high vs low gain should be a decent improvement in the bass and highs on the 8XX. I notice a pretty big difference between high and low gain on the 800s.

what are you running on high or low?

I found no difference in the two outputs, and would run based on what cable connection I had.

 

[DenverW]

what are you running on high or low?

100% high for the hd800 and all headphones over 150 ohm impedance.

 

[Lickumms]

what are you running on high or low?

High, it is 150ohm headphone. Anything over 100ohms run on high no matter what.

 

[DenverW]

300 ohms for the hd8xx.

 

[Lickumms]

Oh, you are right. IT is 300ohms.

@Kamsang here are the pics I promised you in the atrium thread. As you can see, the larger Mundorf caps needed to be Tetris’d in to fit. They’re just a bit too big to be comfortable, but they work. The red caps are Jansen, which I picked based on their synergy with the mundorf. Finally, Dueland bypass copper on the mundorf. Getting those to fit based on the length of the wires was also tricky, but doable. Tight fit, but none of the components are touching or rubbing together.

Hello there, thought I would say hello now that I finally own a Crack, albeit a heavily modified one, after hankering several years for one.

I am not a builder, hence why several years have passed I guess, but the opportunity presented itself some time ago to have one built for me.

My headphones are the HD800S and Utopia’s, and I really wanted to be able to use my Utopia’s if possible, and be able to switch from 6sn7’s to the Mullard ecc32’s, seeing as I have a few.

After several months of trial and error I now have my Crack, which sounds wonderful and I am really pleased with it. The brief was almost met too, by a whisker, regarding the Utopia’s.
These headphones really do sound good with this Crack, even with deep bass from guitars etc. The only time the bass gets into trouble is with some EDM, and when there is a constant deep electronic bass in the background, whereby control is lost.
Well, I’m a happy bunny as I don’t have much of this music in my collection.
A few pics.
