Lamm ML1.1 & ML 2.1

"I have lots of headroom with these amps"

It really never ceases to amaze me as to the amount of headroom on these amps.

Oneobgyn and Dmailer,

I have been following this thread and wanted to let you know I just replaced VTL Ref 750's with the Lamm ML2's on my Kharma 1-E,same as the 1-DDE .

Althought the VTL's are a truly great sounding amp,Lamm's are the most musical on this speaker IMHO for all the reasons outlined.

My experience rolling tubes wasn't as positive with the Telefunken's, but perhaps I had a bad tube. The stock tubes from Lamm were the GE 12ax7's, and they sounded better.

I am told that this speaker also responds well to biamping, which may be the next threshold and scary with 4 Lamms.

I am a tube rolling fool, next week when I receive mine, I will roll with 10 pair, or so. I will then give opinions.

The only ones to play with on this amp is the 12AX7

Have a look at this for the holy grail of 12AX7's

1400, hmmmmmm, I tell you the truth, I have both 1950's smooth, and ribbed plate. I ahve always felt them sterile sounding, bright, thin, unmusical. I normally like the Amperex, which I have 1957 d getter, longplates. I also have tung sol's, raytheons, mazda(silver plates), and a whole bunch more. I will post my opinions later. As far as the 803s is concerned, I feel the rarity of these tubes do not coincide with the sound.JMHO.
