Our Verdict 
A lovely object and a splendid amplifier, the CAP-2100 is a gregarious and eloquent communicator
Monolithic build, fancy-pants interface
fleet, precise and musical sound
Unspectacular specification
could carry more weight at the bottom end
Reviewed on
The only integrated amp in Canadian manufacturer Classe's range borrows from the circuitry of the company's CP-500 preamplifier and CA-2100 power amplifier, and shoehorns the lot into the curvaceous, bombproof casework that is part of the firm's signature.
Consequently, the CAP-2100 is a luxuriously finished and hefty device – no harm in warming your muscles before you hoist it onto your kitrack.  
Speed, agility and control
Like other Classe products, the CAP-2100 uses a handsome set of customisable menus via a touch-screen that's a fraction less responsive than you'd like.
The on-paper spec is nothing special – power is 100 watts per channel at 8 ohms, and three line-level inputs (one upgradeable to a MM/MC phono stage), a tape loop, and a pair of balanced inputs alongside a preamp out is the bare minimum at this price. 
Yet where it counts, the CAP-2100 sounds well worth the outlay. Whether you're listening to Mark Ronson or Mahalia Jackson, the Classe delivers a fast, detailed sound with an exciting amount of insight into the midrange, especially vocalists.
The soundstage is large and sharply focused, and tonality is beautifully judged. Some might hanker after a little bass to go with the spectacular speed, but with thoughtful system matching the CAP-2100 is capable great things.
