i dont hear any hiss at all on my low impedance w5000 and w1000, it's dead silent. i suspect it could be your source or your cable
connection.

penchum: how do u take the volume knot off? do u just pull it out?
There is a small hole with a Allen Head set screw in it. Once loosened, just pull it off.

No, its not my source or my cable. Its definitely hisses with my Denon D2000 even with nothing connected to the MK V. I guess 25 ohms is just too low.

Isn't there somekind of plug-in adapter that changes the load to like 64ohms?
I could swear I saw someone posting about it a few weeks ago?

yeah it's called impedance adapter, they can add impedance load (75ohm, 100ohm)

Thanks BK! Dual, there's your answer!

that would help, i remember i read something about some1 asking mr yang to match the mkv for his grado gs1000, mr yang did that by putting a resistor on the output.

The resistor question reminds me of a thought I had that the only thing I would wish the MKV had is a line output to make it also a pre-amp. That, and possibly a gain switch, would make for a phenomenally good value piece of kit.

I just wanted to throw in something I learned about the MKV while I was doing research for the review. The reason it is such a phenomenal headphone amplifier (besides the dual mono) is because Mr. Yang kept all the noise makers out of the design, like pre-amp sections, gain circuits and their supporting circuitry. All of these things would have made a super quiet, super dynamic dual mono amplifier sound just like the competitions. So, in the end run, the absence of these things, helps take the MKV to a much higher level of quality audio and keeps it at an affordable price point. Have a good one!

That's interesting, and makes me wonder about the choice of a "soft" input switch as opposed to a physical "hard" switch. Doesn't that circuitry interfere as well? I guess considering the dead silence I get with just one input connected, that it doesn't? I don't know enough about electronics...

I think the MCU (for switching) they use is totally quiet and does protection duties as well. No spikes when things switch manually or pops. But, the point was that he was zeroed in on making a quality SS headphone amp and noise is almost always an issue in one way or another. He's a gifted individual for sure!

I found recommendations here for Little Dot, and the price is more favourable, so I've taken the plunge and clicked "buy it now". Will let you know how this turns out. Source is a Sim Audio Moon Nova cd player, 'phones are Senn 580's.
now it's tantalisingly close, amp has arrived from china, and right now is in the small post office booth in the corner shop, less than 5 mins walk from my house. i cant get there until saturday as they're only open 9 to 530 and that's when i'm at work x2

I would like to thank you, Penchum, for taking the time to complete this very detailed and informative review. Although I own the amp, I also wanted to know what others thought about it.

My MK V and Beyers have 110 hours on them now and are doing great together.

I am using this amp as my gaming amp along with the DT990. I am basically cheating by using this setup, as I can now determine exactly where the footsteps are coming from, how many players and if they are reloading. I can hear enemies much further away too. It brings a whole new element to gaming.

Although I am only using it for gaming, I find that it does takes a good amp with lots of headroom to reproduce 6 guys shooting simultaneously and continuously unloading a 30 round clip in 3 seconds. That's 180 rounds at the same time while still being able to reproduce the screaming and the bullet sounds hitting the flesh while producing all the sounds of the vehicles zooming by.

Way more sound than what listening to music can provide. It demands a lot from the amp as the shots are very bassy and the screaming really hits the high notes. I am basically torturing this amp.

That's where I guess the well built seperate power supplies come into play and I am sure they are pulling their weight.

I am so happy to have purchased this amp. In my opinion, this amp should be selling in the $500.00+ range.

Thx

Thanks man! I too am enjoying mine daily. When I listen to my Vintage Pioneer equipment through it, it is so dynamic, clean and not digital sounding! It goes back to the "purity" thing. I hope others will take advantage of the MKV. It really is an awesome solid state amp!!
