The preamp section of the Margules is great, but the amp section seems to run out of grunt in the bass and becomes a little strident in the upper mids if listening at more spirited levels. The Revels can be a bit power hungry for current. Revel claims they’re 8 Ohm nominal, but testing shows they’re more like 4 Ohm with dips to 2.5-3 Ohm.
Plus, I’d like a more granular volume control. The Arch-3 is almost 3dB steps from the remote.
The Margules has a lovely tone though, and loves to assist the speakers in creating a tall and wide soundstage. I’d like to keep that aspect, hence the Lux.
Selling the Arch-3 was always going to be a challenge. I knew that going in, small company from Mexico, not a well known name, all that. Plus, they introduced a new model, the Arch-4, this year. Luckily I don’t need money from the Margules to make the Lux purchase happen.
