The sound is wonderful and about as smooth as you can get. Class AB amps are quite inefficient power-wise, and Class A amps are even less efficient than that. There is a price to pay for this inefficiency: Heat! The S300+ runs HOT.

– Damping Factor: 1500 to 4000 (167 % higher!)

Reviews:
First contact with the KECES S300+ Stereo Amplifier by Dean Waters @ positive-feedback.com
“It’s a real joy to listen (and re-listen) to recordings on a better version of my own speakers thanks to the KECES S300+.”
“If you’re facing a choice to either upgrade your speakers or upgrade your amplifier, choose the latter. Upgrade the amplifier first. As the KECES S300+ shows, you likely have no idea what your current (or new) speakers can do if your amplifier is sub-par compared to the true capabilities of the speakers.”
Keces-S300+ Stereo HiFi Power Amplifier & Speaker Utopia Sound Master @ www.audiophile-heaven.com
“Keces S300+ is actually not even very pricey, and for a Class A/ AB unit, it is literally one of the most powerful, but heaviest, and most controlled, full and detailed sounding amplifiers on the market today. In fact, those statements remain true even if we exclude the price point from the discussion. Keces S300+ is a tank of an amplifier with even more power than a nuclear reactor, and its value is incredibly high, if you need this kind of power. Even when you don’t have the need for it, the kind of control, punch and delivery it offers for a pair of speakers makes it a worthy investment.”
