Believe I'm gonna look into one of those next year. I moved my big hard drive and the UH-7000 over to my laptop, which is still running whatever OS Apple refers to as Catalina. Maybe Tascam will release a firmware update that will allow it to work with OS 11.6, which took 5 hours to load Friday night/Saturday morning and wiped out the printer and the Tascam interface capability on my Mac Mini. Got the printer working by connecting over a USB cable instead of blutoof, but the Tascam wasn't having any of this Big Sur stuff.
So I can listen just fine again from a computer, which saved me some money that can now be pointed towards a Sugar Cube if they ever start making them again.
