Product Description

Small, sleek, and sonically spectacular. Those are the hallmarks of the Qinpu A-6000 MKII vacuum tube 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. The A-6000 MKII also excels as an audiophile headphone amp. 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. The Qinpu has one RCA input, two mini-plug inputs, a mini-plug variable line-out/headphone jack, and quality speaker binding posts.

Customer Reviews

I will recommend this one to anyone who want to try tube amp.

To me, the Qinpu sounds like a very well designed solid state with a slight tube coloration thrown in.

This amp sounds very good out of the box and I was very impressed.

Verified Purchase
The Qinpu A-6000 MKII has got to easily rank as one of the top audiophile bargains of the century, given it's low cost and true high end, superior sonic quality. I received the item within a few short days, and it was boxed and protected very well (double boxed), with ample styrofoam-like packing surrounds. The amp itself looks and feels very well made, and clearly belies it's low price point for what you get. After hooking it up, and turning it on, I noticed blue LED lights, one behind each tube, blinking on and off. After about a minute or so, they stop blinking, which signifies that the amp's tubes have warmed up sufficiently to now use it. My bedroom system consists of the Qinpu with an Oppo DV-980H SACD/HDCD/CD/DVD 'universal' player, going into a pair of vintage Polk Audio studio monitor 10's (circa 1986 or so). Speaker cables are Silver Sonics T-14, and interconnects are Straightwire Symphony. I could not believe how great this amp sounded from the very beginning (and dead quiet too, when source material was not being fed it), with no 'break in' time on the stock tubes! After just a few hours of listening, the amp really started to 'bloom', with liquid warmth, resolution, and natural timbral accuracy matching amps that cost several times the Qinpu's price of admission. I was, and remain, absolutely dumbfounded at what I heard, no matter the genre of music I fed it. I can't wait to see what further sonic merits 'tube rolling' the unit's 6N3's may net in the near future (if anyone knows where to find NOS tubes for this Qinpu, please leave a comment here). Incidentally, the unit only gets slightly warm to the touch, even after a few hours of listening at healthy volume levels. Thank you for reading this review, and please post your experience with the A-6000.Read more ›

This is a great sounding amp! There isn't much to add that hasn't already been said about the A-6000. It's very well built, feels solid and has some weight to it. I am using it with some JBL bookshelf speakers and a sub and it is pleanty loud. I think this could push full size speakers with no problem.

What I can add is regarding the tubes. This amp is so good that the cheap stock tubes that come with it still make this amp sound good. If you want to change tubes, you will be looking for 5670, 2C51 or 396A. The GE are the least expensive ($5-10 ea) and I have heard they sound good. There is a GE 5 star ($20-30 ea.) that is supposed to be better and Raytheon tubes ($10-25 ea), square and windmill getters with the windmill being the better of the two. The best tube, from my reading, is the Bendix but they are expensive and hard to find and can run $75-100 ea. The next best tube is the one I got. I have the Western Electric 396A. They can run $50 ea. but I won an auction for a pair at $30. WOW, what a difference! This amp is scary good. I'm sure there are better tube amps out there but I'm going to guess that you would have to spend thousands to impove on this one. The new tubes made the music come alive! I'm very picky about my sound and I have never heard anything like it. My tube amp search is over. I have a high end Hitachi solid state amp and this is so much better! It's also dead quiet! My only complaint is that I would like a headphone jack on the front. There is an out on the back of the amp you can use for a sub or headphones, but you have to undo the speaker wire from the post to use it with headphones. I have some monster U connectors on my speaker wire that makes this easier. It is a little inconvenient but not a deal killer.

Buy this amp, roll the tubes and you won't be dissapointed!

There are a ton of reviews on this fun little integrated amplifier out there. So rather than state the obvious and say for the umpteenth time that
(1) It sounds great, and even if it cost 5x its current price it would be a winner sound quality wise - provided you value musicality and some warmth in the delivery, and provided your speakers and volume level preferences match the power rating of the A6000.
(2) It is a price-value *steal*. Even if you have a far more expensive system, it's fun to get one just to play around.

My primary system consists of a Benchmark DAC2 HGC (still to be reviewed) that gets FLACs and some MP3s stored on my computer. The Benchmark then feeds into 2 amplifiers I rotate, an Accuphase E-306v as well as Creek Destiny Power Amp. Why do I rotate them? Because the Accuphase -my keeper for life- gets serviced and upgraded every once in a while. So I have had other amps over the years. The speakers used to be BW 804s, but I have them in storage because they were too big for my new place, thus I recently acquired the KEF LS50 (which utterly blow my mind). Cabling is good, but never esoteric, I have never spent more than $500 on a cable, and typically buy cables in the $100-200 range from Kimber or Analysis Plus, perhaps spent more on the speaker cables though. The reason for all of this is I love listening to classical and jazz music (which I store as FLACs) with some popular contemporary hits thrown in of course (and MP3s are fine for those, most popular music is poorly recorded anyhow). Long preamble - this is to say: I take my music listening seriously.

The biggest compliment I can pay the Qinpu A6000 is... a friend of mine was home-bound because he broke 2 legs badly in a motorcycle accident.
