"Such High Quality at This Low Price"
Sometimes big things really do come in small packages. The tiny Qinpu A3 hybrid vacuum tube/solid state integrated amplifier packs a mighty high-end wallop. It delivers a beautiful room-filling 8.5 watts per channel. A pair of 6N3 output tubes contribute to the velvety and detailed sound. The oversize transformer adds most of the weight to this hefty little titan and contributes to the low-noise performance.
Warm and Natural Sound
If you haven't heard your music through a tube amplifier, you don't know what you're missing. The high-quality analog circuitry delivers warm and natural sound. The rear panel mini-plug output lets the Qinpu A3 double as a headphone amp whose performance will shame the built-in headphone output on many audio and video components.
"I Can't See How They Do It!"
Audio Advisor sales rep Joe Darmogray spent a lot of time listening to the A3 and says, "I just can't see how they do it! Such high quality at this low price. It drove my Sennheiser HD800s flawlessly with power to spare. Tubes just seem to mate with headphones. They give you silky smooth highs that make you just want to keep listening. It's an integrated amp to boot! It drives my Energy C-300 just fine."
"Character and Depth"
Joe's not the only one who admires the Qinpu. According to TubeAmpliferReviews.com, the A3 "is a decent little amplifier that… adds character and depth to the sound that similarly priced solid-state amps might struggle to."
The Ins and Outs
The Qinpu gives you a surprising amount of connectivity for its small size. In addition to the headphone mini-plug output your find full-size high-quality gold-plated binding posts that accept spades, pins, bananas, and bare wire speaker cable termination. Inputs consist of one pair of RCAs and a mini-plug auxiliary in.
"Sweet Little Amp"
This sweet little amp looks and sounds fantastic," raves our customer Travis C form New Jersey. "It drives my Mission 701 speakers to room filling levels with the kind of sparkling hear-through sound you only get from tubes." |
