I also own an ARC VSi60 as well ass the Leben. Both highly recommended, but very different amps. The ARC is noticeably more powerful, and quite a beast in terms of grunt for its rated output. Typical ARC sound - incredibly accurate, very clear and open, almost solid state, but with a bit of added tube ‘bloom‘. Great all round performer.
The Leben compensates for its lower power with a greater degree of finesse, and sheer musicality (probably the best commercial amp I have heard in that respect). Can still rock it out with efficient speakers. Hope this helps.
