from one review
A prominent sonic wallop is likely the first thing you’ll notice when firing up the C5i. Bass is particularly well controlled, as is transient attack. The California Guitar Trio’s “Led Foot” demonstrates the C5i’s ability to maintain pace while simultaneously keeping separate and clean the three distinct guitar voices. California Guitar Trio records contain a wealth of musical information in a small space, an acoustic that most moderately priced integrated models fail at recreating.
Bill Bruford’s
Earthworks lies at the opposite end of the sound spectrum. A skilled drummer that never hesitates to maximize his kit, Bruford provides a great torture test. The C5i has no problem keeping the cymbals in their own distinct space as the percussionist takes flight on several rapidly paced solos.
Comparing the C5i to the much larger REF500M monoblocks reveals a close resemblance at less-than-earthquake levels, and for good reason: The C5i uses the same power modules, albeit in stereo rather than in a bridged mono configuration. Again, Bel Canto doesn’t sacrifice sound quality at a lower power level, making the C5i an even more attractive proposition regardless of where you sit in the audiophile pecking order. And diversity abounds.
The high-level outputs give it even more versatility for listeners that desire a satellite/subwoofer system. Users that either don’t want or can’t get speakers right now should think of the C5i as a wonderful headphone amp that happens to have a great DAC and phonostage. It adequately drove the new Grado PS500, Audeze LCD2, AKG 701, and Sennheiser 650 headphones. Yes, you can drop another $500-$1,000 on an outboard headphone amp, but this one works well and is miles beyond any pod or tablet
