So, I just got home with a newly acquired Lyr 2 to use with my Teaks and HD650.
 
Paired with the Mimby I just got from a fellow head-fi'er, I was pretty blown away on the Teaks. I had enjoyed my Vali 2/M2U previously, but this just felt like another level entirely.
 
I feel like I'm missing something though, because I find my 650's just sound muffled and lacking, especially on instrumentals. 
 
Trying to convince myself to get accustomed to this sound first before I dive into tube rolling.

Replacing the stock tubes will make make a considerable difference. From my experience anyhow..

What sound sig are you looking for?

Tubes for the HD650 I would suggest Voskhods, Siemens, Reflektors or Telefunkens, these are quite common and are usually reasonable priced but they also will have some premium ones that are quite pricy these days.

I found that it needed some time for the LYR 2 (with stock tubes) to reach an optimum and waited before coming to any conclusions...but I'm ready now for some experimentation. As a matter of interest, has anyone tried the LISST with HD650's ?

I am currently finding that these less expensive tubes are working great with the HD 650:
 
 6N3P-E OTK Reflektor - NOS - 1977
 
However an adapter is required.

good info to know, wish I had known about adapters and alternate tubes when I fist started, could have saved a few $$$$ between the tubes for my Lyr2, Ember and BH Crack.

This is also an adapter required good match for the HD 650:
 
396A Western Electric - NOS - 1976
 
IMHO,

This is good info for those just starting this crazy journey, I've got a supply of tubes to easily out last me, 46 pairs for the Lyr2 at last count, and it does not include the tubes for the Ember/BH Crack, which can share some of the same driver tubes but I still have a bunch of 6AS7, 6080, 5998, and 421's for the power tube of the BH Crack.

Me, earlier tonight: "Oh. Huh. I wonder if the 650's would sound better in high gain mode."
 
Me, now: "Yep."
 
It certainly sounds fuller and more detailed, less muffled/muted, but importantly not just louder.

You are not alone. I had the very same thought with my LCD2s a few months ago. High gain is better with certain headphones.

I agree. LCD 2's are listenable on low gain but I feel like they are running at 100% of their potential on high.

Can anyone gimme a comparison between lyr2 and jotunheim (Balanced marks as powerful as lyr2 approx) ?

Lyr2 is a little more flexible due to being able to roll tubes, Jot is a little on the bright side IMO, really bad with HD800, D700 and T1
