AKG K812 Pro
Oct 27, 2013 at 3:43 AM Post #46 of 4,825
I hope it works fine with my Macbook Pro and iPad with an Apogee One for on the road. Price is not in issue if it delivers the quality and is very easy to drive. I do believe speakers / studio monitors are better at home use, hence why I'm not investing in headphones that are difficult to drive like the HD800. 
 
I'm also interested to hear how much better the AKG 812pro is in comparison to the Shure SRH 1840 (which I'm currently using). I'll be looking to upgrade from these headphones if the difference is signifcant enough.

Assuming the K812 performs better off lower-end amplification while the HD800 performs better off higher-end amplification, I wonder at what (amp price point) the two would crossover...

yea i think the k812 would b an obvious improvement. From day one these have screamed APPLE Friendly at me n it seems the akg web site confirms that.

I wonder that as well chicol
but can we expect amps to even b worth while or dedired in a rig based around iPortables?

Still waiting to see how the Lcd X compares to the rest of the totls amp wise

To be fair, an easy to drive headphone doesn't mean it don't scale with amp. If anything, it will be very picky about the amp and source. Instead of wanting more voltage swing, it will want a bit more current and while doing so, sensitive to output impedance and noise level compared to most of the less efficient flagships out there.
 
All Audio Technica are very easy to drive, they don’t nearly sound as good as they are driven properly with a good amp than using a smartphone. It is just that, they are not unusable on smartphones and such.

on I know that. my w1000x is picky but this is n akg. on top of the fact that akg made this to target n auidance with a weak source... each company n product r designed n target different ppl. So we r not speaking in terms of all senditive low imp cans just this totl

  To an extent, yes.  However it would be wiser to include some type of white or pink noise analysis, as various combinations of frequencies and their harmonics can interact with themselves within a chamber and your own ears HRTF when actual music is played.  This is also why listening for yourself is important, when possible.  Or at very least, carefully analyzing subjective impressions.  A sine wave sweep would really only be ideal if the electrical signals were wired directly into the sensory neurons of your brain

I've done test measurements with both white noise, sine sweeps, and MLS signals, and I'm not sure that there was much difference to the shape of the response overall. This was in a measurement setup that models the anatomy of a human ear fairly well.
 
I'd think it's easier to spot irregularities in a sine sweep than in a block of white noise, but that's just me and I know some like to use the noise.

I stand corrected.  Very comprehensive approach.

I still feel listening to noise if well it's too silly for me. Granted I can see the application, but I always like to test with actual music. Granted I can see how a Sine Sweep would be great for listening to the headphone, getting a feel for the drivers tuneing, but what's the fun in that.
 
Still I respect the guys who can sit through that stuff! Then again I listen to the same 7 songs about 3 hours every day... [literally] which most likely is equally silly xD

32ohms but razor is bang on the money which I've stated before low-z appreciate more current than voltage where as high z need more voltage swing than currents due to the less damping factor from the low-ends.
 
32ohms and the applied sensitivity sounds like my CD3k/SA3k/SA5k and even the Qualia 010, need something like an Luxman P1u or BCL on high gain to drive it nicely, possibly the M-Stage will fall into this category as well. I should be able to head down to A2A and listen to these when the time draws near.

too bad they will cost 1750 euro (incl vat) in Belgium according to my local akg dealer...price is way too steep for me if it wants to compete with the hd800.
 
I wish I could atleast hear them, see how well they'd compare to my balanced hd800 setup.
 
it does seem like a great thing they can atleast perform great from a source like a phone etc.

It would be great if K812 turned out to be a real competitor against HD800 for many reasons. One of them being that it could motivate Sennheiser to develop and introduce a new flagship (HD850?) sooner:)

Do you mean 1250 euro? For 1750 eur, its really a joke (as well as LCD-2 and LCD-3 are here pricewise).

no, I meant 1750 euro. This isn't a typo.
