Hegel C54 Power Amplifier
A multi-channel amplifier designed for sound performance... not priced like diamonds. And still tailored to your needs. Sound too good to be true? Well, it used to be, but not any longer. The Hegel C5 series: 3, 4 or 5 channel power amplifiers are rack-mountable, configurable, specified to your needs and will - most importantly - blow you away with their sound performance. Up to 5 channels of 150w/pc analog amplifier power, with enough Ooompf to boogie with almost any loudspeaker on the market. Meet the Hegel C5 series.
Introducing the most versatile high-performance multi-channel amplifiers on the market - the Hegel C5-series. The C5 is available in 3 different versions, tailored to your needs. You can choose to have it as either a 3-channel, 4-channel or 5-channel configuration. Meaning you can build a 5.1 or Atmos theater using one or more C5’s. Perhaps you want to bi-amp speakers or use active cross overs? You could also use it to power multiple speakers in a mastering studio, in a restaurant or in a home. In short, wherever you need high-performance sound with dynamics and ultra-low distortion.
As flexible as it is, the C5-series of amplifiers still maintains the full Hegel Sound. C5 uses the patented SoundEngine2 technology with its many benefits. One of them is the possibility to run low bias, meaning the high power class A/B amplifier do not run as warm as normal, allowing you to install it in a 19” rack. Another benefit of the SoundEngine2 is the very high damping factor (more than 2000). Higher damping factor means deep, deep bass and complete control of the bass drivers. It is one of the reasons people are talking about the dynamic Hegel sound. Yet the most important is its low distortion. Hegel’s patented SoundEngine2 amplifiers work almost like a noise-canceling headphone. All distortion elements created within the amplifier circuits are dynamically canceled out, by being played back in a negative phase. So no matter how you choose to configure, the C5-Series will deliver a spectacular soundstage. Never hard or unpleasant. Always natural, smooth and with incredible dynamics.
Versatility stretches further than the number of audio channels and ways to use. The ability to switch phase individually for each channel or selecting between different gain settings for each channel makes it so much easier to integrate into a larger system. The trigger input and output (allows daisy chaining) means you can place it in a separate room and never worry about switching it on or off. The C55 is 3u tall, with massive rackmount ears that are an integrated part of the amplifier shell. When installed in a rack, we recommend 1u spacing on top and bottom. There are also adjustable and detachable rear mount ears. If you do not choose to install it in a rack, feet are supplied in the accessory box. Meaning, the C5-series can fit in any application.

If I was creating a home theatre from scratch and my amplifier budget was up to $2,000 per channel, I would go with as many C55 amplifiers as needed for the number of channels and save a bit of my budget to use elsewhere. At this point, in early 2019, there's no other amplifier I would even consider in that price range. Used in an appropriately sized room with any "reasonable" loudspeaker load, I don't know of any other amplifier that makes movies or music sound better than Hegel's C55 without spending much more to get it.
