AKG K601 & K612 Pro Owners... UNITE!! - Page 57

post #841 of 2230

Initial thoughts is that sonically they are very similar.  K702 have a touch more air and resolution.

Huh interesting. I thought the same about the K701 vs K601.

It's funny - from other people's comments about the K612 just being K601 with new 'paint job', and other comments that the K601 were darker - I was expecting something very different than what I have here now.

 

For me so far, it's a typical AKG house sound - very flat, but accurate bass (with normal roll-off in the sub bass), flat through the lower mids, upper mids a little bit forward, a little emphasis on the high end (not as much as the K701/K702 though).

 

Warmish and light (as opposed to dark, and bassy).  I like what I'm hearing so far.

Did you ever have the K601 before? How about the Q701?

 

I found the K601 to be warmer and fuller sounding than the K702 but sort of not quite as detailed or clear. I think it has a lot to do with the K601 having flat pads and less treble. Flat pads usually give you an impression of less treble. K601 seemed pretty close to being dark. I found it to be close to a mix of a K702 and maybe a HD-600.

 

I actually found the K601 had more upper mids than the K702 though and some peak really bothered me at times but was only really noticeable with harsh music. I'm sure they fixed that with the K612.

 

I really don't know if the K601 and K612 are the same, but probably close.

 

K601 to my ears actually sounds better for rock music than the K702 for whatever reason.

 

When I got the Q701 I immediately sold the K702 and K601. Q701 (but not the K702) is actually fuller sounding in the mids than the K601 IMO.

 

BTW I'm not sure if you noticed but the K601 is a little harder to drive than the K702. Needs maybe 5-10% more volume on my amp.

 

Oh yeah.. the K400 EP I have has similar treble as the K601. It's very smooth and kind of rolled off. The K400 LP is quite trebly and has more than my Q701 for sure.

Your impression of the 601 vs the 702 is spot-on. Warmer and neutral vs forward and airy. The 601 is 120ohm and the 702 64ohm so the volume knob is typically higher with the 601 for the same spl. Though in terms of amplifiers the 601 is more forgiving. I can amp it with whatever I have and it excells. The 702, for me, requires a warmer amp with current to spare to sound good.

If you want a real treat, use the 701/2 pads on your 601. You don't lose any of the warm velvety goodness of the 120ohm 601 driver but gain more air, soundstage and instrument separation than with the small, restrictive stock pads.

@tdock - I currently have the K612 and K702 (so side by side comparisons).

 

I've owned both the Q701 and K701 in the past.  Haven't heard the K601 before.

 

@Punnisher

You're right - re the specs.  K612 is both higher impedance (120 vs 62 ohm) and also lower SPL (by about 4 dB).  It needs more power to get louder.  But interestingly out of a low current source (iPhone - no amp) - the K612 actually sounds better.  The K702 loses a lot of the bass and lower mids - and sounds quite "tizzy".  The K612 doesn't lose quite so much in the bottom end.  Guess it has something to do with the very different driver design.

 

Out of my NFB-12, everything sounds the way it should do (for both cans).  Was quite an interesting contrast.

Good point - just checked the pad difference - and the K612 have flattish circular pads - while the K702 are angled at the back and slightly thicker.  Swapped them over and immediately slight difference with the soundstage - and appears to have a little more air.

Interesting! Any negative effects on the sound of the 612 when using the 702 pads? What happens to the bass? Which are the more comfortable, In your opinion? Thanks.

Have to do more in depth listening - but comfort is about even.  But no cons in using the angled pads that I can see.

Thanks for the impressions. I've been intending to sell my K601s since they don't offer me anything I can't get from my HD580s, but I wonder whether a pad swap to the K702 pads might give them a new lease of life ...
post #851 of 2230

Unfortunately I don't have my HD600s operable at the moment (waiting for replacement drivers) - but my interest in the K612  was to compare it with the K702 - then decide which one to keep.  I love the AKG house sound, and actually find that either the K612 or K702 compliment the HD600 more than compete with it.  May be a moot point soon anyway - as I know ultimately I'm probably either going to end up with RS1i & HD600, or RS1i and HD800.

 

I only got the K612 today - but already I'm loving the signature.

 

With the angled pads - the differences aren't startling - so they're not going to make the K601 into a new headphone (not IMO anyway).

post #852 of 2230

OK, fair enough! Many thanks for your impressions.

post #853 of 2230
Awesome impressions Brooko! Does that mean the K612 Pro can be driven straight out of the iPhone?

Nope.  You get volume at around 75-80%, but the bass and lower mids aren't all there.  It is slightly better than the K702 out of an iPhone, and the K612 doesn't actually sound that bad - but it is pretty noticeably bass light.  With enough amping - it sounds normal again.

post #855 of 2230

This matches my experience too.  I've got 3 amps: Fiio E7, Fiio E10 and a Matrix M Stage. I find the E10 to be fine for driving the K601, sounds no worse than from the M Stage. the E7 wasn't quite up to the job though, the bass wasn't quite all there.
