Wasted Years

Only downside is this product is so good it makes me feel all the years I could have been recording with this were wasted. Now remixing everything old besides new stuff. It really is worth the money!

Excellent Little Unit

This may not be as glamorous as the Duo and it will have a lot less DSP of course but if you already a new PC/Mac then all you need is an interface to run a decent amount of UA native plug-ins. What I do like though about this Solo I s that it still offers you enough DSP to track through a pre amp or and amp sim along with one of the legacy compressors too for example. I’ve recently recorded a well known amp sim thru the Solo with the API on the Unison bus and the LA2A Legacy & I thought it gave it a nice little push in the right direction sound wise sounding very good indeed. I also like to off load a master compressor to the solo too just for that extra bit of fun too. All in all I’m really please with this product and really don’t feel I made an error not buying one of the more expensive products.

Very limited Windows support

The windows support is very limited and the interplay with WDM drivers make for a bad experience

Perfect form factor and portability

One dsp to tracking vocal and voiceover is enough for me. Fit perfectly on my desk, i love it. :)

Okay, but Insufficient DSP

I bought this for traveling. The bus power was a selling point. And I knew the DSP capability was lower... but it's too low to be usable. Like I'll add VOXBOX to Unison, and then I can't add a 2nd plugin (e.g. most reverbs, echos, saturators, etc). The Apollo Solo doesn't have enough computing power.

Also it MUST be powered by your laptop which I didn't realize. I figured I could power it off a newer USB-C PD PSU, and that the Solo would just use its last config. The idea was to use it as a versatile mic preamp (SM58 > UAD Apollo Solo > 1/4" line level stereo). But nope! Gotta have the laptop providing Thunderbolt power (not simply USB-C PD). My mistake for not understanding that before buying.

So my overall opinion is I would not buy this and instead just rely on in-the-box plugins. Since you need the laptop on regardless. There's not much benefit to this Solo interface given the severely restricted DSP power AND given its reliance on a laptop if you're using it as a standalone preamp.

The Apollo Solo Thunderbolt 3 exceeded my expectations. It is a spectacular audio interface. I use it every day and get great results. Simply fantastic!

OK, overpriced

I got my Apollo Solo and after a few weeks of use, i'm pretty disappointed. Converters sound good. As good, as converters on my other interface, which is much cheaper. Latency on Apollo is higher as well. DSP is pretty useless, it has very littile computing power, and with current latencies I don't see any reason to use Unison, i just add native plugins in my DAW.
It also doesnt offer any modern connectivity, like ADAT/SPDIF/AVB/Dante.

It works good as my "travel" audio interface and heapdhones amp. It looks nice. And IMO the price is not justified. Generally, i'm rather disappointed with the UAD products, and especially their very game'is, unclear pricing

Apollo Solo is so good.

I was surprised when I actually saw this for the first time. Because the appearance is really beautiful. The appearance made of silver is simple, and it feels really luxurious when you touch it. And because it works with bus power, you can record anywhere with just a MacBook. 그리고 With a loopback function, live streaming is also possible. Built-in DSP chip allows for latency-free sound delivery in live performance. And I can connect my Apollo X6 and Thunderbolt to expand the number of inputs to make it 8 inputs. I was thinking about Apollo Twin X, and I'm glad that this is a really good choice.

Above expectations!

I pretty much knew what to expect - solid, high quality audio interface with DSP. I definitely got that, and was also surprised how good it is for headphone monitoring. UA Console, plug-ins and luna are first-class products, too. I can only regret getting it too late!

Excellent work

Great piece of hardware to place in you arsenal. But if you are into heavy mixing you will need a UAD satellite, but it is still an empowered interface, small and portable as well.
