| Qinpu - A-6000 MKII - Integrated /Headphone Amplifier |
Smooth, Luxurious, and Detailed
Small, sleek, and sonically spectacular. Those are the hallmarks of the Qinpu A-6000 MKII hybrid vacuum tube/solid state integrated amplifier. The Qinpu delivers a smooth, luxurious, and detailed 16.5 watts-per-channel at 8 ohms, enough to fill your room with beautiful music and to easily drive a wide range of loudspeakers.
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 variable mini-plug output lets the A-6000 MKII double as a headphone amp whose performance will shame the built-in headphone output on many audio and video components.
Torroidal Transformer
A pair of 6N3 vacuum tubes in the output stage are responsible for the A-6000 MKII’s highly musical performance, along with an oversized torroidal transformer, which contributes most of the heft to this little amps 6-lb. weight. This advanced power supply responds quickly to musical signal demands and keeps operating noise low.
The Ins and Outs
Qinpu packs a lot of connectivity into the compact A-6000 MKII. It has one RCA input, two mini-plug inputs, a mini-plug variable line-out/headphone jack, and quality, full-size speaker binding posts that accept bananas, pins, spades, or bare wire.
"Fit 'n' Finish Are Very High"
"Fit 'n' finish in this price range are very high…" notes Srajan Ebaen in his Janaury 2009 review for 6moons.com. "The pricing of course is a major attraction here."
"Really impressed with this amp," raves our customer Fred D from Massachusetts. "Driving a pair of the Cambridge Audio S-30 bookshelf speakers, the sound is glorious. Big soundstage, great imaging and very pleased. A no brainer purchase." |

"The pricing of course is a major attraction here. For old men with money, too; but far more relevant for younger gals and guys on lean budgets."
"Fit 'n' finish in this price range are very high…"
"I didn't have a Sonic Impact-type amp on hand to confirm Fang's claim that the 6000 MkII smokes their kind for breakfast. I do know that as part of this review system, the 6000 was clearly the perfect tool for the job. As you'd expect, given that one firm designed it and the speakers."

Great office amp |
| Purchsaed this along with some Audioengine P4 speakers. Nice combination. Coupled this with a Hegel HD2 DAC from my laptop. Sound is amazing and at high levels, minimal distortion. Gerat for a small office playing jazz music. Cant wait to roll some 5670 tubes versus the provided 6N3 and hear the dirrerences. Great bargain. |

One of the most audio component that I ever heard!! |
| Its got this natural dynamic range with richness and warmth as well as its ability to let the sounds natural,gracefully decay with the black backdrop.Create an excellent sense of musical flow. Youll probably become quickly addicted to it........ |

Best Investment Ive Ever Made |
| Two weeks after purchasing my review is, this is incredible. It sounds so warm and clear and beautiful. I had never owned tubes and wondered how loud it could go, not that I play loud music, but its just good to have the power. I have never turned it up past 40%, i.e. it has more than enough power to please a LARGE room. I wouldnt hesitate buying another one. |

For the $ unmatched |
| Been an active stereo serious listener since 1966 I have had Sherwood Marantz Onkyo,Denon,Harman kardon,Nad receivers/amps. I set the Qinpu on top of my Nad and cd player..Hooked up to my RA labs,Roy Allison speakers and my grado phones. It was a true warm vocal, acoustic, loving machine with great harmonics and a different feeling of air space around the performances them tubes got some kind of sound stage softness like it was not straining like a cool calmness, the standing string bass sounded there. The horn sections true to tone vocals smooth buttery I played in the school band trumpet,bass,guitar. I know live music nuances and tone not only was I surprised for the money I was grinning like I got away with something. Does anybody out there know how good this amp sounds talk about economy audiophile equipment. Give it a try the amp is beautiful the blue and orange glow of the tubes wood with brushed allum. It drives the Ra labs great I just wished it had a speaker switch for headphone. I had to disconnect the speakers to use phones and another rca input would be nice but the sound for the money you will have to experience for yourself. |

Great for my 1st one |
| I bought this amp and a pair of Sony SS-B3000 speakers from here at the same time. Its my first tube amplifier of any kind. I had an Alteg Lansing 2021 computer speaker/subwoofer combination and replaced it with this new equipment. Its a vast improvement and the base of the speakers keeps up with the subwoofer turned up slightly which is where I always had it otherwise it was too boomie. You cant beat a dedicated subwoofer cranked up and I knew that going in but Im still very satisfied with the low range as well as the mid and high end of my new speaker/amp combination. I will recommend this amp to anyone wanting to go back to the superior sound of tube amplified music. Ive only had them on for about an hour but they say after 25 to 50 hours these amps and speakers will seek their own break in point and sound even better. Im feeding the amp with music from my computer sound card which is pretty unclean and it sounds very nice. The tunes are at 128Kbps at 44Khz joint stereo and MP3 so I can feed it much, much cleaner music and I cant wait to do so, for example a CD player right to the input. Im looking forward to listening to stuff I have ripped in FLAC/VBR or FLAC/CBR format and even HD FM stereo fed from a Sony HD tuner tuner only at 300mV line output power. Oh, power-wise I was little worried as I like to jam every once in a while and I was concerned about its 16.5 WRMS per channel. Its plenty loud so dont worry about this aspect and this is using a pair of speakers mentioned above whose 88dB sensitivity isnt that great. If you use speakers that are 91dB 3dB more, a key delta sensitive and higher, then youre even doing better in the loudness/volume department. It was packed very well but the input selector switch had some nics on it as well as one of the metal footies so thats the only reason I didnt give it a 5. Im sure the parts were in a big box or something before being placed on the unit but perhaps this is indicative of QC but none the less I love this product so far and I am now inspired to build my own single ended triode amp. It doesnt look that tough. |

Audiophile bargain of the CENTURY! WOW! |
| I usually dont like to review equipment, BUT in this case, I just had to! I have my A-6000 driving a vintage pair of hi-res Polk Audio Monitor 10 speakers, and the sound is absolutely mind blowing incredible! Timbral accuracy, euphonic, sweet, and detailed come to mind. My SACD player sounds spectacular going into this tubed integrated amp. Im dumbfounded, given the low price! |

Holy smokes |
| I ordered this for my desk top.I could not believe the sound,I was in state of total disbelief at the sound quality,it sounded better than my 8k main system.So i got a second one and replaced my stereophile recommended amp in my main system.Wow ! this has to be the deal of the century.Highly,Highly recommended ! |

Great unit |
| I bought this amp for the headphone section as I just bought a pair of AKG 702s. While it did not drive them to the level desired the quality of sound matched my V2 Musical fedelity headphone amp. Were it realy shines is as an intergrated amp. It plays my Triangle celuls to near full volume. the quality of sound is on par with my older Pass lab amp. Only my conrad johnson has less grain and greater micro dynamics. Dont think twice on this one, Audio Adviser will not be getting this one back, infact I will be getting one for my daughter so I can have the sweet spot back. |
