  Or try cables that are known to have a warm sound.  Use copper cables as it tend to sound warmer than silver cables.  Like other have said only a software eq is the other solution.  
 
Of tubes that I know sounds warmer sound signature are Ken Rad black glass, VR102, Mullard ECC32 those come to mind.   


Excellent suggestions. Copper cables aye. Thanks.
 
I'm going to put those tubes on my wishlist also.
 
Hey if I dropped the treble 10% I would be a lot happier.

  add another foam layer over your headfone drivers.


I was wondering about that. Does it work?
 
Would it effect other things? Soundstage etc....

Okay. I will give that a go. Plenty of space in the Audeze to insert in the ear cups.

I was doing some research on what will be the ultimate 6SN7 Addict's amp. & I think it will be this :

Does anyone have any other contenders (amps which use 6sn7's as primary / main tubes , like this one    http://www.iconaudio.com/portfolio-item/icon-audio-hp8-mkii/  ) ?

In my opinion, Glenn's OTL with a 6/12/25V heater switch is a strong contender for the "Ultimate 6SN7 Addict's Amp".
 
But then, I currently have what could be considered a poor-man's Liquid Glass Hybrid: a modified Little Dot 1+. Like the Liquid Glass, the LD is a hybrid, but with rollable op amps in the SS section. While designed to run two triodes (actually, two triode-strapped pentodes), I have added a 9-pin breadboard socket and a continuously adjustable (up to 25V at 4.5A) DC heater circuit. Granted that I need to use pin-adapters to correctly reroute pins, but I can roll all the tubes Cavalli lists for the Liquid Glass, and more. For example, I have used 8CG7, 9AQ8, 25SN7, 7963, C3g and tubes from the 5687/6900/7044/7119 family. I have even ran a 6AS7 as a driver. lol. And the total cost of the LD1+ plus mods was less than $200!
 
But if all one wants to do is roll 6SN7's, and perhaps 12SN7's and 25SN7's, I would suggest that Glenn's OTL is the ultimate 6SN7 addicts amp, for a quarter of the cost of a Liquid Glass. And again, with pin-adapters, it should be possible to roll all the tubes listed for the Liquid Glass. (The only one I am not sure of is the 12AT7, which might have too much gain: 60.)

Right my Glenn's GR Super 10 can use 8 6SN7's for output and a 6SN7/12SN7/25SN7 driver, including some of the ECC derivatives.

Man....I can't wait to get my hands on  Glenn's  OTL !

Now that has to be the ultimate 6SN7 amp can run on all 6SN7s.
Don't forget six 6BL7s for outputs for the best sound. 
I just got Amine a set of 6BL7s for spars and going to give him some rectifiers 5R4G and 5AW4 to try.

Hands off please? Unless ya were already looking then it's fair game.
 
Any thoughts on these tubes? I don't really find much info. Raytheon 6SN7 WGT Chrome tops.

Very Nice. Do all the 8 6SN7's have to be matched ? Is this an OTL amp ? Does it use a Rectifier tube ?


No the output tubes don't have to be matched.
It uses the same transformer and rectifier as your amp.
Sounds best with 6BL7s but it can use the 6AS7 and all it's variants also the 6336.
Yes it is a OTL.
 

 
With 6BL7s
 

 
With 6AS7s

Glenn it can take 4 6AS7G's and all the fancy U52 rectifiers.
