Confirmed. I love the combo. I liked the Crack alright, but Glenn's amp is just better.

In what way are they better?

  Glenn is a doer, not a talker.
 
Sweden I know you have the HD800 in mind, I don't know if anybody has tried them with Glenn's amps.
 
The T1 pair nicely with Glenn's OTLs some owners will confirm this.
 
I am pairing my GR 6SN7/LP2/5998 OTL with my Maestro GMP400 and my GR Super 10 with my K701's and I am very pleased.

 
Yes the HD800 is a very picky headphone that IMO need some tube lushness to give them a soul.

  If you want a amp for the HD-800 it would be the OTL
I have the HD-650 and Hd-800 and there is no amp that sounds better with these head pones
then this OTL and the fact that it will take 6336 as well as the 6AS7 makes it able to drive many headphones.

 
Glenn, do you think the 6336s work better with certain headphones and the 6AS7s with other?

Nice neat bundling. Are those Russian KBG/MBGO PIO as couplers? They look good in there.
I've had my eye on some of those for between stages to replace some polypropylene I currently have.

I like the 6AS7 better with higher impedance headphones like the HD-800
but with lower impedance head phones  120 ohms and lower the 6336 sounds better.

Yes they are the MBGO I only use these and Sprague vitamin Q for coupling
The bypass capacitors are Sprague Atom For electrolytic I only use
Sprague Atoms or BC components a little expensive but worth it.

Looks very nice.

The BL63 tube
 
This is a tube that people ether love or hate.
Playing with this amp and tube all morning I like the sound the problem is the operating points
of the 6SN7 are different then a BL63. So when somebody just puts a BL63 in a amp that is running
a 6SN7 at low current it will sound bad.
In this amp I run the 6SN7 a little hot so the BL63 sounds good it is a compromise though the owner
wants to be able to run the BL63 as well as the 6sn7.
I would like to make a amp that is made for the BL63 so it can sound it's best.

I own a TC-754 (silver) 4-way input extender with integrated phono preamp. If he can wait 3 months then it is his. He'll have to find a 220v to 12v power convert wall wart though. So just say the word and I'll bring it with me when I move in.

 
Clayton,
 my cousin finally dropped by to pick this up. he wanted me to thank you VERY VERY much. thanks!

My amp has the Vitamin Q's right?

 

[2359glenn]

  Looks very nice.

Thank you
 
Your amp is more versatile though

Yes you have the vitamin Qs in your amp.

I really think the Crack sounds constrained compared to the Glenn's amp. Don't get me wrong though - I liked the Crack and Valhalla, but I am selling both. If you love tube rolling, a Glenn OTL is great. If you like to tinker, the Crack is for you. The Bottlehead forums are full of crazy mods folks have done to that amp.
 
After thinking about it, I'm going to go put my T1s on now.

Have you tried the speedball upgrade and upgraded tubes for the Crack?
Constrained in the soundstage?

 

[wotts]

I do have the speedball in my amp. As for tubes, I really only chanded the driver out. I didn't have any extra rectifiers at the time. Currently, it's in a closet.
 
I guess you could say the sound stage was smaller, but it's more like the music was pushed. Glenn's amp has flow. Does that make sense? I could be just talking out my ass here too.
