I got an LTA Aero DAC on 4 April 2026. (I didn’t do six comparisons, but I did compare it to a Lab12 DAC1 Reference and the internal DAC of my Marantz SACD 30n player.)
One interesting thing is that I ordered the Aero with stock tubes. (I like to do some tube researching and rolling, having a tube pre and a tube phono stage.)
I was expecting the stock tubes to be GE 12SN7 tubes. (That’s what all the reviews had said.)
It came with RCA 12SN7GTA tubes. RCA tubes were the ones I was planning to get to roll in.
I do not know if somehow I got really lucky and someone at the factory made a mistake, or if these are now the new stock tubes.
But they sound excellent—as does the DAC.
Aero DAC by Linear Tube Audio - experience
I am looking for other Audiogoners input and feedback. Feedback from people that tried it and bought something else after trying it. As well as Audiogoners that bought it and use it.
I have read it is fantastic value, compare to Audio Note 4.1. My impression it is a wonderful to have a tube dac with a streaming service as it creates a nice warm analog like sound to digital input.
Thank you!!!

Glad to hear that, @hoodjem. Isn’t it nice when the universe smiles on you?

I have the Aero now for a few months and the tubes can make a difference. Mine came with GE 12SX7 tubes and I found those to be sterile sounding. I then tried the Ray Reserve 6SN7 and they sound better, but not quite as good to my ears as my NOS tubes. Currently I have been switching between Sylvania 6SN7GTs, RCA 12SN7's and Brimar CV1988's. The RCA and Brimar tubes help tame harsh digital.
