Anyone familiar with Air Tight ATM-1S?


I’m looking at an ATM-1S power amp, but haven’t owned an EL34 based amp before. Right now I’ve got an Elekit TU8600S with WE300B’s pushing some Volti Razz. I’m digging it, but I’ve been curious about Aor Tight gear for a very long time. 

If anyone had experience with Air Tight ATM-1S or el34 vs 300B would be much appreciated

@yomaha Yes, I agree that the ATM-1S would be plenty powerful w/98db speakers. I recall carrying it into a dealer to demo speakers bigger and lower sensitivity than my own and it outperformed a 75 or 100w amp they used as their normal demo pairing.
I'd guess the ATM1-S would sort of split the middle between what you get from the Elekit and the Pass(my fav SS amps in general). Cheers,

I have LOTs of experience with AirTight el34 based amps.  They are outrageously good.

my favorite is the ATM-3 mono blocs.  

but the 1s is nice.  Just not the ATM-3 performance.  NOTE: I am thinking about the prior version of the ATM 3's.  not the newer vertically oriented very expensive ones.  The older version are basically bomb proof and can be had for a very reasonable price on the used market... a few pairs come up every year.  But you have to be patient. 

if you want to know more, send me a private message.

NOTE: they respond well to tube rolling.. especially vintage NOS Mullards or Telefunkens.  Tube life is quite good.  And easy to bias.
