So good I need 2.

I came here from a Gen-1 Orion32 (9+ years), and I miss the simple i/o and the extra 16 channels. However, once I wrapped my head around Apollo's mixer and figured out the messed up way Pro Tools needs to be routed, something is just working for me. Not only can I route out to my hardware with just as much ease, but the latency is reduced and the converters feel like a bit of a step up. What else can I say, really. For the price I'd prefer more bells and whistles, but it's an investment I REALLY am satisfied with. I trust it top to bottom, which is not something I've ever been able to say before.

Tremendous piece of gear

Paired this with two additional Apollos with ADAT functionality so plenty of options to work with, but the x16 is a beast. Crystal clear, tons of DSP for both recording and mixing, 5 stars for sure.

Missing piece

Running this through my Neve 5059 and a stereo back into my X8, and it sounds amazing. To not be able to get a credit on some plugs when you have the legacy is a major minus when you buy at this price range.

No Immersive Audio Support

We did a demo with an x16. Great sounding unit. We currently own multiple Apollo's and external dsp satellite units. You have to spend an additional 3k minimum for 7.1.4 monitoring. It should be easy to add that capability to this unit. We requested it at AES in 2019. With Logic, Nuendo and PT all featuring Dolby Atomos, the x16 would be a natural.

Great product but it would be great if this product has madi or adat conection

It is great but it is sad that this product has no Madi or Adat connection. (like Apollo 16)

Apollo 16x

Love UA gear. So much so, I bought 3 Appollo 16x for my Trident 24A board. The only thing though, you'd think UA would throw in some plug ins. How can you not include the Plug-In Promotion Deal. And I bought three of them. Not happy about that. I'm told there's nothing you can do. If I hadn't already bought them I may have chosen something else.

Need true 7.1.4 Dolby Atmos capabilities...

I would love to see a redesign for the X 16 unit which will handle 7.1.4 Dolby Atmos for those of us who need it and we need it badly!

Apollo X16’s x3

Absolutely Amazing Converters, Cant beat the Sound Quality and Near 0 Latency. I Bought 3 for My Console and I Wouldn’t Go With Anything Else.
Although The Price Jump Over From around $3,200 to $4,500, And It Being EXCLUDED From the Apollo Rack Plug-In Promotion Deal Despite Being the Most Expensive Flagship Rack Mount Interface Without any Explanation Beside “Thats Above Us, We Don’t Know Why” really left me with a bitter taste in my Mount. Especially After Buying 3 of them!

Twin and the improvement in conversion is quite noticeable, thanks UA!
