Could it be a power supply issue ?
I suppose Amir re-checked that...

And this little thing probably is not smart enough to require a USB-PD-enabled power supply able to provide more than the usual +5 V (USB-PD can now reach up to 48 V !)

Actually, if we think the sample may be damaged why give it a headless panther in the first place?
For the time being, the verdict seems a bit harsh to me. Headless panther can have serious impact for a company.
IMO get a second unit to test or wait for a vendor response.

It appears to be a random "slap a name on stuff and sell it' marketplace product sent by a user. I don't think there's any reputation to damage. That said, I'm sure Amirm would add a correction or put up a new post if it was needed (eg. if this particular unit was broken).

Jokes aside it’s probably broken ?
There's the irony. If Amir tested a broken device sent by a reader in unknown condition, and reported incorrect results without checking in with the manufacturer despite seeing their snr and distortion figures don't match the 22.8 db SINAD ... negligence? Recklessness? Protected speech? I have no idea.

Benefit of doubt: this is so bad that it could easily be a broken sample.

More doubt: but their font uses a lowercase A as a lowercase D and their Y is an I with a lowercase C on it. Which tells me they probably didn't bother to install an actual English font on any computers at the factory to make the logo look good. If their marketing "department" (probably one guy who also runs the silkscreen machine) is that lazy, they might have also copied the specs from someplace else, too.

If we want to drag the ghost of Tekton into this... well, Amir tested the unit he has and published the result as-is, even if there's reason to believe the sample might be broken. This is the same thing Stereophile has been doing for decades. They both give the manufacturer a chance to respond if they want, which is not something the law requires, so much as journalistic integrity.

As long as Amir didn't break the unit himself to make the measurements look bad, I don't think there would be any question of legal liability here.

This all presumes the manufacturer can be contacted. Perhaps if you bought the item new it came with some kind of contact information. But based on Google searching, I can't find any way to contact them. Some online third-party sale listings suggest the company behind Linepaudio is Carevas, but that is a dead end as well - there's a Carevas.com but the site is mostly dead and it's not clear what they even make or if it's the right Carevas.

So if someone sends in a piece of gear here and the maker cannot be reached, or even known for sure, should Amir simply not test it?

The fact that something is shipped broken is of interest to membership as well. Remember, it is a practice among some companies to specify chip specs and not real measurements.

This has nothing to do with warm sound because there are also tons of uneven harmonics and a clipped sine which again also has zero to do with warm tube sound.

Thought folks here were more knowledgable than this...distortion =/= distortion, it all boils down to what kind of distortion you have and in what amount.

There it is. The perfect tube-amp mod for "warm" sound.

Surely it's broken
Could be worse: it's not broken-in. I mean, burned in. You know, same as cables. They never sound good without 300+ hrs of burning-in. Better with good music.

Let me enlighten you: Even the expensive, good tube amps while claiming to bolster mostly even harmonics also bring along a lot of uneven harmonics, making it basically just a distortion machine, more or less looking like this broken device here.
Basically all of ASR-reviews of tube amps have proven this. So the "warm" sound tube-enthusiasts fawn about is basically just raw distortion.

Knowledgeble people on ASR know about this. Now you're welcomed into this educated circle too.

Yes, but that doesn't make it any less "warm". Warm is just the name people have given to certain types of distortion. On the music production side there is a whole cottage industry devoted to creating software that has various versions of this "warmth". :)
