"Overall Sound Quality is Amazing"

'Tiny' may be the best way to describe the Qinpu Q2 hybrid vacuum tube/transistor integrated amp, but it doesn't begin to convey the compelling sound quality. And once you consider the low price, the Q2 gets even more amazing as a compact sound system for your PC, iPod, and other sources that use a mini-plug connection. It also has RCA stereo inputs for plugging in a CD player, DVD player, or other component.

With 2.5 watts of stereo output power, the Qinpu has enough muscle to push a large range of speakers with articulate and harmonically pleasing sound. A pair of speaker binding posts makes connection easy. Or plug a pair of headphones into the rear-panel mini-plug jack and enjoy the Q2 as a high-quality headphone amp.

"The Tube Adds Color and Depth"

The 6N3 vacuum tube contributes to the Q2's smooth sonic output. "The tube adds color and depth to otherwise cold signal sources like CD or MP3," notes James in his November 5, 2009 review for TubeAmplifierReviews.com. "It allows the listener to experience some of the benefits of tube amplifier at a fraction of the cost of a high-end tube amplifier."

"The overall sound quality produced from the Qinpu Q2 Desktop Amplifier is amazing. I couldn’t believe the smooth sound quality the little feller produced, reports Munk at OverclockersHQ.com. "It is a great buy for a very decent price and is a lot more self-expressive then your average generic off the shelf PC speaker system."

"The overall sound quality produced from the Qinpu Q2 Desktop Amplifier is amazing. I couldn’t believe the smooth sound quality the little feller produced. The bass was smooth, mid was smooth, and due to the solid-state integrations the treble was very bright. If you like bright treble but smooth mids and bass like me this is a great little amp. Jazz sounds amazing through this amp."

"This is a truly hi-fi roots amp which seems to work very well with both digital and analog accompaniment. Which means plugging in to your record player will sound just as nice as plugging into your cd player on this amp."

"Would I recommend this amp? Yes, it is a great buy for a very decent price and is a lot more self-expressive then your average generic off the shelf PC speaker system. If you include some stylish red Qinpu speakers you have your self a very art deco style going on Flash Gordon himself would approve of."
