Thanks for the kind words, @SHXMD and @George Hincapie. Two years is a long time indeed. You may recall, we showed the first prototype of the Aero at CAF in 2022! We used the Aero last weekend at Southwest Audio Fest with a full LTA system (Aero, MZ Pre, UL+ monoblocks), and it sounded...

Here are a couple more polished photos we just posted to our website...

If you listened to the Velo at CanJam NYC, you also heard the Aero. We had two Velo units - one at LTA's table and one at Meze's - and they were both connected to Aero DACs. :)

They're in the output stage. Sort of like the 12SN7 / 6SN7 tubes in the MicroZOTL. Yes, changing them will affect the sound.

It will look exactly like the Velo, except wider (and no volume control, two fewer tubes). We'll have the Aero in the final case at CanJam NYC this weekend, so look out for photos from there...

FYI, the Aero we're bringing won't be in a case. We're still waiting on those to show up, unfortunately. But you'll be able to get pics of the beautiful insides!

Here's the full list of what we plan to bring: Amps: Z10e electrostatic + dynamic headphone amp Velo headphone amp / preamp Aero DAC Headphones: Abyss: Diana MR Audeze: LCD-4, CRBN DCA: Corinna Meze: Elite, 109Pro ZMF: Atrium

If you're willing, they'd be a great addition to the meetup, I think. We (LTA) will be bringing our Z10e electrostatic headphone amp, so people can use that to listen to these headphones.

Hi. We'd love to have photos to post, but one of the major things we're waiting for in order to begin production is final case parts. Until then, the best we can do is 3D renders.

I'll see what I can dig up at LTA HQ and bring it along... :) Most likely: Z10e electrostatic + dynamic headphone amp Velo headphone amp / preamp Aero DAC A variety of headphones from Audeze, ZMF, Meze

We just added these and other specs to the Aero web page. The output is 2.2 Vrms via RCA, 4.4 Vrms via XLR.

As @obstacleofaffliction suggested, swap each set of tubes and see if the noise changes channels. When/if it does, you've found the culprit. We have a video that demonstrates this process with a full integrated amp, but the process is the same with any tube amp:

Yep! We just posted a video about this a couple weeks ago: https://www.instagram.com/p/CsWZf5gNLn1/

Note that this is a pre-production prototype, so it will look quite different when it's released. We had the same DAC with a different build (more compact) at the headphone area at Axpona, for example.

Definitely going to be Q2 at the earliest at this point. Sorry I can't be more specific. Too much is up in the air right now, and we're a tiny company, so roadblocks and shifting priorities can affect things unexpectedly. I also can't answer any questions about the design or features - see...
