Probably a bad idea since the modded Q701 itself with K712 pads has way too much bass (IMO). It was kind of nice, but then it just ruins some songs.

I ordered these from RazorDog Audio while they still had the 25%-off discount (which is code razor712, btw) and they just arrived today. I've been looking for a particular type of sound for certain music genres and figured they'd be a good fit.

 

I'll start by saying that I've owned a few of the K70x-series headphones over the years—the original K701, the original K702, and the K702 65th Anniversary. Never really thought that highly of any of them, even the K701 which I used with the most number of different amps (solid-state, hybrid, & tube).

 

My initial impression of the K712 was more of the same K70x sound and I wasn't impressed at all. In fact I was almost getting ready to send them back.

 

That is, until I decided to do something a bit different. I have a review unit of the Garage1217 Project Ember here with me at the moment. I was using the stock 6N1P tube with the K712 at first and tried out the Low, Mid, & High output resistance settings, none of which really improved anything. So I rolled in a different tube, a 12AX7VKA, and left the amp alone powered on, but not actually in use playing music, to "warm up" the new tube for a bit. A few hours later I came back to test it out.

 

My reaction now to the K712 in the re-configured Project Ember w/ the 12AX7VKA at Mid output resistance (35 Ohms) is HOLY CRAP! I don't think I've ever heard an AKG K7xx headphone sound this good before! No it's not at the level of the HD800 or LCD-2/LCD-3, et al. It's actually better, and I mean that seriously! For the price that I paid, heck even at the $500 MSRP, it's awesome-sounding that in a lot of ways eclipses the HD800 and Audezes! I honestly can't believe how good the K712 is and it totally puts the other expensive flagships to shame. Easily. And when it's a fraction of their price that's an insult!

 

I pity those who are going to under-drive the K712 and won't hear its potential. Because my other amp, the HeadAmp Gilmore Lite, totally and obviously under-drives it. The K712 sounds like a joke on it. But it sounds great, borderline amazing, on the Project Ember where it's driven properly!

 

I used to be a non-believer of AKG's K7xx headphones but the K712 has swayed me back. It's really good and makes sweeter music than any HD800 or Audeze, or any other dynamic or planar magnetic before it that I've owned/heard.

I always thought when an AKG has an ideal synergy behind them they are truly a treat and pleasure to listen to. They are so musical and engaging with the right system and some reason I find the systems that really bring out that musicality also bring out more of an AKGs refinement and resolution. I have noticed when I heard the K712; it does sound a bit different than the other K7xx series, I want to hear their full potential some time as I think the system I heard them on wasn't ideal. My K612 on my system awes me all the time they sound so real and musical, they just became so good after I changed tubes on my amp.

Ha, I just ordered the K712 and am planning on getting the Project Sunrise in the near future. I'll have to grab one of those tubes and give it a go.

A Gilmore Lite can't drive a K712 properly? I find this kind of hard to believe..the K712 isn't that power hungry. Doesn't that output like half a watt into 32ohm?

 

Even between the O2, iFi iCAN and my Headroom Micro Amp there is no massive difference and those are all pretty close to transparent IMO.

It does sound the best on the Micro and that thing has TONS of power. I do think battery powered amps are usually a fail with the Q701/K712 though. I haven't tried any of the new ones likes the E12 and C5 though.

 

IMO when any AKG is under-driven they're usually thinner and more tinny/harsh in the treble. To get this type of sound from my stock Q701 it takes one really awful amp. People say the Q701 and K712 are often fatiguing, but I never ever get this unless it's the recording's fault and even then this almost never happens.

 

 

On a transparent setup i've not found the K712 and (bass) modded Q701 to sound that much different. I'd say they're about equal. Q701 stock and K712 is a much greater difference obviously.

 

BTW not sure if you'd agree, but i've found the K400/K501 to be the hardest AKG headphones to drive.

 

I also wonder what you'd think of a K712 on an O2 compared to your Gilmore. IMO the O2 does a good enough job of driving the Q701. I felt the iFi iCAN was slightly better, but more closed in sounding.

Or Asr didn't like at all the pairing and blame the gilmore to underpower the poor little K712 ?  :o

post #2423 of 4054
That's my assumption.

People equate a bad pairing with being underdriven half the time, which is just misinformation half the time.

Hell, I've underdriven some headphones that sound better than being well driven off the wrong pairing. It's rare, but it happens. Like using a Magni with a bright headphone.

Anyone know who sells replacement pads for the 712s, Google isn't my friend at the moment. Need to give mine a wash. Thanks.

Frank at AKG has them.  Part no. 5021871

 

 

Spare parts

Phone:  +1 818 920-3279

 

 

Be warned that you MIGHT not get the same K712 pads back, as the K712 and K702 Anniversary share the same part no. for pads but are slightly different.

 

Are your pads really dirty enough to need replacing already??  The K712 hasn't been out that long...

Thanks a lot. Mine feel like memory foam ones, not going to send the ones I have anywhere though, just need a wash. See if I can't buy a spare pair.

post #2427 of 4054

My advice is don't let it exposed to anything. Put it in a drawer xD

Right, I'm saying if you BUY A PAIR, there is a chance the pads you receive might not be the same as the pads on your K712.

I think you should be able to wash them as long as you rinse them good and air dry them very well (set it in front of blowing fans). 

 

I would just wash them first.

Okay, thanks.  It's very long thread, forgot half of it from last time I looked through it.

post #2430 of 4054

Is there any guidelines on how to wash those pads while not damaging it? I am not sure what kind of material inside the pads, not sure if using some detergent or shampoo will cause something bad to the foam inside the pads.
