The c50 integrated amplifier is designed specifically for low-power applications where highly-efficient speakers demand the purest electronics. This means smaller power supplies, lower heat dissipation, and simpler circuitry allowing the amplifier to better communicate the essence of a musical performance.

The c50 uses a number of techniques that prove indispensible in amplifier design: eddy-current reduction, four terminal T-network capacitors, and feedback compensation optimized through listening tests. Based on the award-winning Opus 21 series, the C50 amplifier incorporates years of experience into a stunning amplifier, both sonically and visually.

The most distinctive thing about this amplifier is its beautifully machined shell. This stunning piece of industrial design makes the Cantata products stand out a mile. If there were any justice in the world, then this amp would be on the front of the finest design magazines in the land. It probably also accounts for a fair portion of the final cost, but when you consider its sculptural qualities, it’s money well spent.

Build quality is very high throughout, not only is the machining on the shell itself state-of-the-art, but the buttons, display and connections are all top notch. It’s not a big amplifier, width is about average but height and depth are petite, continuing the less-is-more theme. The speaker terminal sockets are deliberately minimalist and, therefore, don’t look very classy, but there is the option of having conventional binding posts, too.

In terms of value, it’s not so obvious what you’re paying for apart from the casework, at least until you plug in a great source and speakers and spin some choice tunes.

Try as we might, we couldn’t think of an amplifier under ¬£6,000 that comes close to the musical transparency on offer here and that equals great value in our book. Read More
