I owned the Arros for a few years and am confident that the Classe would provide sufficient power. While I've never heard the Classe, 100 watts should be good for your stated needs. In my experience the Arros sounded better with tubes than solid state, so perhaps you could look into a Unison Unico or Vincent Audio integrated as "clean looking" solid state/tube hybrid options (as for solid state, I've heard that Plinius and Simaudio integrateds both work well with Arros). I really liked the the sound of EL34s with the Arros, so consider a Jolida 302RC, Rogue Cronus, or VTL IT-85 as well.
Is the Classe Cap-101 enough for Totem Arros?
I'm looking to setup a small simple 2-channel system in my living room. I live in a mid-rise condo so I dont crank to much and dont have tons of space to fill. I am looking for a decent small integrated receiver with a remote and the Classe Cap-101 seemed like the first. The upgrade would be the Cap-151 or something else entirly. I will primarily use the system for acoustic/folk/rock some Jazz/Instrumental/blues but also this will be connected to my TV for home entertainment in this main room also. I love the Arro's so I just want them to be the centerpiece of the livingroom in my condo. Need a clean looking integrated amp to pair with them.
