HOLD UP!
You do NOT have to send your unit ANYWHERE to get tube replacements.
1. If you buy tubes from the authorized service centre (which I obviously think you should), they keep a record of your amps measurements.
2. If you're the kind of person who owns a $5,000 to $10,000 amplifier but is not willing to pay the mild premium to get it factory serviced (which I do not understand), any competent technician can figure out tube settings.
The service centre mails the tubes to you.
There is no sending units back anywhere.
I have owned two different Audiomat amplifiers, and tube replacements are a breeze.
Audiomat amplifiers sound absolutely incredible in my opinion, and they can be a tremendous value.
With Audiomat because they are integrated amplifiers you eliminate the cost of a separate preamp, and an expensive interconnect.
After years of switching from one integrated amplifier to another, then from one pre / power combo to another, I bought the Audiomat Prèlude Référence and it stopped me in my tracks. I had it from 2011 until 2017, and the only reason I sold it was to buy an Audiomat Opéra Référence.
I previously owned the Audiomat Phono 1.6 (which was excellent) but recently picked up the Audiomat Phono 2.0, but am still waiting to install it in my system.
In my experience, Audiomat products are exceptional sonically, but they also seem to communicate the emotion of the performance a lot better than other gear I have owned in the past..
The Audiomat thread referenced below contains the voices of a few people who are not necessarily the right owner for an Audiomat product, along with a few voices who I think are (including me).
If you are a "tube roller", Audiomat is probably not for you.
If you are a "DIYer", Audiomat is probably not for you.
If you want the reliability and ease of use of a solid state amplifier, but the magic of EL34 tubes and custom wound transformers (and the musicality and magic that comes along with it), Audiomat is probably for you.
If you want to hear the uncompromising vision of the designer of your amplifier, Audiomat is probably for you.
Honestly, give this stuff a listen and if you don’t like it, fine. But it’s exceptionally musical stuff, and it deserves the utmost respect and consideration from any audiophile that fits their target market.
Another reason to think carefully about MUTINE .... PITA in having to send the unit back to MUTINE for tube replacements.

A sampler:
".... I know from experience that a Audiomat OPERA REFERENCE has to have the 4 El34L replaced my Mutine themselves.
They keep a record of each OPERA REFERENCE according to serial number and they then
send El34L tubes which are numbered to fit the proper tube socket..."
