So the iCan is 100% balanced. See the homepage.

Have a look at the Neo. The case is beautiful and appealing. But the data did not convince me. Too little power, then xBass and 3D function is missing. Once you had them, you don't want to miss them anymore. Therefore I bought the Signature. It has more power and the mentioned functions.
Signature and iCan are similar in sound signature. iFi Sound. I love it! The iCan is simply much better in every respect. It is also a different price range. Costs 3 times as much as the Signature. You can also expect more. What is ingenious there are the tubes. You don't have a real tube sound like with pure tube amplifiers. But there is an excellent tube touch. Especially with recordings that were recorded a bit "hard", it sounds great. But you can also turn it off and switch it directly to pure transistor amplification.
Compare Signature and ADI. ADI has even more setting options. EQ, loudness, bass and treble controls. You can adjust 1000 things. Sound it is more neutral. Performance comparable. But it is not balanced. Unfortunately also balanced HP outputs are missing. You can now do that with the Signature via the 4.4mm output. From the sound I like both.
My best combination but absolutely ADI with iCan. This is real high end. So you can also intervene on the ADI with EQ if necessary. But it is necessary, but you could do it and you have all the settings via ADI. Runs as DAC and preamplifier to the iCan. But you can also use the ADI directly. As soon as you plug in headphones, it automatically switches to speaker outputs and switches off the line outputs. Excellent solution.
As I said, for me this is the dream combination. I use Signature at my 3rd workstation and also mobile to iPad on the terrace.
All 3 are good, the question is what to spend. But you can really live alone with anyone. The headphones are also important, the differences are even greater there.
What I also have is the Burson 3XP. This is a DAC/Amp. Very neutral in sound. Sounds completely different than the iFi devices. It harmonizes perfectly with Audeze HP. I use it for LCD-X and LCDi4. Absolutely outstanding. As I said, very neutral and still musical. The iFi have a more powerful sound and are also more aggressive. I like that.
The iCan is the US muscle car. The iFi is the well-kept Mercedes S-Class. The Signature is a pimped up turbo small car!
