Qinpu Amplifiers are integrated amplifiers coming with a headphone output mini socket in the back panel, so all of them can drive headphones. Their chasis are made by metal, very heavy. Sound signature is so musical that you will never feel tired when you listen to them.

Hey Fang, how many watts does the A6000MKII output?

Also, how many ohms are the V1.8 speakers (2,4,8)?

You can read more about it at Qinpus webpage: CHPO AUDIO

They are 4 Ohms with a sensitivity of 84 dB/watt I think! can't read Chinese so can't really be sure.

I just want to say I am impressed so far with the Qinpu A-3 amp for driving my AKG K1000 and my Stax SRD-7 Pro transformer with HE Audio Jade. I will be doing a write-up within the next week on this, as I am just below 200 hours of burn-in and wanted to make sure it was run in properly. Naamanf listened to this yesterday and was surprised at the sound from this $299 chinese amp, and liked the machining done to the metal enclosure as well. The 1/8" line out also can drive a headphone nicely, and is not just to be used for a subwoofer (just like how my Apogee mini-DAC 1/8" is a line out that can drive a headphone). For source I am using a PS Audio Digital Link III and iPod 5.5G iMod with lossless via a DLO homedock HD with it's optical output into the DL3 DAC. I am told the DLO converts the iMod analog line out to optical, and is not a bit perfect like Wadia, but it sounds at least as good as an iMod via $800 Jensen Copper foil cap dock.

I'll also report on the Q-1 radio/amp soon - I have one set up with an Apple iPod dock on the CD input, and a full size headphone amp plugged into the 1/8" output, and the speaker out are going to an SRD-6 with Stax SR-Lambda and book shelf speaker connected to the SRD-6. It makes a nice rig for listening to the radio and ipod via headphones, stax and speakers. The 2-watt amp has no trouble driving the speakers, but I haven't listened to the Stax yet till it also passes 200 hours. Previously this rig was being driven by an old Optimus (Radio Shack) mini integrated 5-watt amp, with a Sansa e240 as the FM radio, and the Q-1 sounds much better.
