This hybrid Shengya A-216 is a Class A/B amplifier with total power (150w per channel). It uses (2) Chinese ex-military miniature pencil (Beijing 6N16) vacuum tube per side in the preamp section. Such a design provides not only the clarity and punch of a solid state amp, but also the warmth of tube sound in music reproduction. Shengya is considered the indisputable best hybrid amplifier manufacturer in China and absolutely among the top of the world.
The Shengya A-216 Hybrid integrated amp is great to look at, pleasant to listen to, mix well with home decoration and definitely perform beyond your expectations for its price tag. If you look for tube sound but cannot resiste the power of solid state amp, A-216 is for sure the way to go without hurting your wallet.
As the reviewer Kent Johnson from Positive Feedback Online put: "The Shengya A-216 has considerable strengths. It is extremely well built, absolutely quiet, powerful, offers balanced inputs, has sophisticated controls, and is maintenance free. Economically, it eliminates the need for tube replacement—at least for any of us currently alive, uses less electricity than a tube amp, and costs only $1850. And it sounds incredibly good, too."
