Anyone familiar with Air Tight ATM-1S?

Thanks for the review @three_easy_payments. Will def check out.

@spencer - thx for feedback on the el34 tube style. I’m a rock n roll guy at heart so that goes a long way for me. Very tempting. 

The 300B Elekit is a Japanese designed kit with Lundahl transformers and Mundorf & Duelund caps so it’s quite nice. Like you said, on acoustic and jazz it can be spooky good on a solid recording.


My speakers are 98dB sensitivity so the 36w from the ATM-1S would probably go a long way. I also have a Pass XA-25 that I really enjoy. I’ve kept it around and plug it in when I want more speed and slam than the 300B’s.

@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,
Spencer

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.
