Love my MOTU AVB units. Have 2 828es units and chain them together for a super flexible array of ins and outs. One unit had an issue and MOTU did replace it within warranty. They were very quick and easy to work with so that was a positive experience.

A little nervous about the M1 compatibility comments here though. Anyone else using MOTU AVB with an M1 computer? Planning on upgrading pretty soon.

I've used my Motu Ultralite AVB and my Motu 8D (each by themselves and when connected via AVB) with my MacBook Pro 16 (M1 Pro chip) without any issues.

Let me know if you want to sell it.

There are a lot of misconceptions deriving from differing experiences.
I have a couple of Black Lion modified 828 mk2's from back in the early 2000. Discontinued years ago. And I have a Black Lion micro clock for clocking them.

A couple of years ago, I had problems with the synchronization setup for the clocking, as I found the Motu software dialogue a bit confusing.

The Motu tech spent literally hours on the phone, during two days, helping me out. He called me back and followed up on it.

There was no issue with discontinued support.

I also remember back in the days of firewire issues, driving both Motu and RME owners crazy, motu told me early on that it was not their drivers, but windows related. Later it became clear that certain intel chipset and windows, was an issue in this regard.

Due to the outstanding service I have received from Motu, I am now running a pair of 24Ao and 24Ai, with my 2 old 828 mk2's and a RME Octamic, as AD/DA converters. Everything running with the BLA micro clock.

The sound from the new devices, holds water big time. They might be even better if upgraded with BLA, but I do not trust their services any longer, due to their new practice of not answering to any support requests, even from retailers. Customer care counts, and I am very happy with Motu in this regard.

I wish I could find more practical help with learning the Motu pro routing and mixing system though.

The problem with Motu is that it dose not offer any hardware related service once it is out of warranty. Their current warranty service essentially just replace your non-working box with a new one and call it a day. I hope your Motu boxes don't break down or you will need to replace them with new ones.

Yes, unfortunately this is true. I was a little disappointed, but I suppose to keep the costs down they offer an awesome warranty and then nothing post warranty. My unit from 2019 is giving me trouble and they couldn't do anything for me, but gave me a lead on a potential fix. So I bought the part and will attempt to fix it myself.

Bummer though, as I was hoping to build on the modularity of this system for some time. If 4 years is the shelf life the value proposition does go down a bit. Still weighing my options. The feature set and sound quality are incredible for the price, imho.

4 years of life span, yikes.

Yeah… unfortunately that unit is bricked… so down to one 828es. Lots to love about it but that one hurt.

I am a bit surprised hearing that.
I know that my old 828 mk2's were serviced for many people for years, before they stopped servicing them, however mine never needed service. They are close to 20 years now, and still running. The support has been great, they spent hours helping me with trying to implement an external clock from BLA, on my then maybe 15 years old units. I highly respect them, as they did me obviously.
I therefore updated the AVB series a few years ago, with a 24Ai, 24Ao, and a Ultralite AVB.
No complaints, great sound, and flexibility. Rock solid on Win10. I also still run a 8pre, and my two 828 mk2's with this system. Motu made this work splendidly.

There was a time I thought that MOTU didn't do good drivers, but I was wrong. It was Windows and Dell, that stole 10 years of firewire problems in my life, not MOTU. MOTU always tried their best.

I found this article today, and someone obviously knows a bit worth knowing about Motu.
I added more about my experience with MOTU, in the comment there. I highly recommend MOTU, and I am not easily persuaded. I am not affiliated at all, just a thankful customer, a songwriting hobo with a guitar (actually about 40), and a quite evolved studio to frame the madness.
