Can't comment on the 224 but I did loan a 480L which was utterly amazing. I have an AMS RMX-16, which I often use. It is magical. Sounds sit so well in the mix when that verb is added. The ambience, hall, plate, room and non-lin verbs are phenomenal. It is so simple to operate. The standard model comes with only 8 or so very usable presets. I upgraded the software so mine has 18 presets. Doesn't sound like much, but I prefer having a dozen very usable presets compared to having hundreds or thousands of OK or mediocre ones.
I have tried the TL Space RMX-16 and 480L presets and they are nothing like the original hardware.
