I think the mods might be adding something that isn't there, but I like it. Changed from a HP I didn't like to one I enjoy for prolonged listening in one easy step, magic!

 

I have removed just the sticker and kept the foam.

Agreed that the improvement is significant and the mod is really easy to do. Just wondering why AKG has put the sticker there in the first place.

2) It really does sound like it's making too much of my music collection sounds like garbage. It's annoying and how it was for me with the old DT-880 I had. Some might not like this. I don't know why there is a change.  Yeah like putting my music under a microscope.

What type of amp are you using? On a tube amp this effect seems less pronounced.

This is with the Headroom Micro and Schiit Modi. To me the Schiit Modi is pretty revealing of things. I'd say they're both transparent.

I also have the O2 and E17 around but don't use them much. The O2 sounds worse than the Micro, but the closest i've come to the Micro Amp sound.

 

I have an Asgard 2 on the way as a 2nd amp. I'll either love it or hate it. Strangely I upgraded from the Asgard1 to the Micro, but maybe the Asgard 2 will be an improvement?

I did the extra-material under the Q badge thing to close the soundstage down more by adding a round, slightly smaller in size layer of coarse microfiber cloth on top of the foam to bring the soundstage yet a little more to the center and now the center image sounds quite a bit more coherent and focused.  No more of the extreme panning effect the Q701 has been occasionally been critiqued on is to be heard.  Of course, that is really just down to preference.

 

At this point, between the extra cloth and bass port it's getting a little bloated here in the mid-bass or experiencing some kind of particular resonance around 100-150 hz, but it does sound quite a bit better casually when you expect a bit of slam from a sound system to go with all the details and screaming mids.  Oddly, it does appear that they are less efficient now and slightly more amp power is required to achieve acceptable volumes.

 

Overall, I'm liking where this is headed.

 

I can see, however, how the AKG engineers must have agonized over having acceptable bass, but the most clean and even presentation of it possible.  The way the mids are stock encourages listening at lower volume levels, and now the bass is encouraging lower volumes too.  I might just have to re-cover the hole and stick with just the extra cloth under the Q.  Only time will tell if the current bass levels will give me a headache, although I suspect that will only happen with the electronic side of my music collection.

If you have a chance, try the modded Q701s on a tube amp. From what I have heard the difference is quite noticeable and it makes poor recordings more tolerable.

Modded Q's + Mullard 161 tubes are just sublime right now. I'm hooked. I can't wait until my new power tubes come in to try out.

If you can, try the modded Q701 with gaming. I've found this to be one of the best ways to hear sound signature differences with headphones.

The differences are now easier to spot.

 

When playing Fallout 3 everything is a little fuller sounding, but it feels more speaker like. A little more clear.

Imaging is very accurate. The sound signature except for the bass doesn't seem any more different. I don't know how this is possible if the mids sound fuller.

 

Strangely if you go into subways that low rumbling sound isn't anymore present. Maybe a tad. I don't know what range it is, but on the DT-770 Pro 80 it almost gave my ears a massage.

My guess is that the Q701 is just accurate here and doesn't emphasize anything.

 

I think the reason it's not more present also is due to the soundstage. There is definitely more low bass but not a massive boost.

 

Character vocals sounds the same but male vocals in the game sound fuller/clearer.

 

Go into Tennpenny Tower and you'll feel like you're really there with the elevator music surrounding you. I haven't experienced it as good since I had the K501.

 

More volume was definitely needed. I was listening to a movie on my TV with the headphone jack and had to max the volume. Normally it's close to being maxed anyway.

This is pretty normal for me since the Q701 is a bad choice for a TV headphone jack. The blu-ray player source was also very weak. The HD-650 actually sounds good from a TV headphone jack!

 

Obviously for gaming I used my E17 and O2 with optical input from my Xbox 360.

 

I will try using Microfiber instead of foam behind the outer grill. I actually love the larger soundstage but not everyone will. It will be interesting to hear any changes.

 

Can't say it enough but for me there are really no sound signature changes except for the bass.

I reversed the mod today to check for any differences...the mod is staying!

 

The first thing that stuck out is that everything in the soundstage seems more shoved forward.

There seems to be less soundstage depth heard. It's almost as if it's non-existent but only in comparison to the modded Q701.

Some recordings seem to have NONE and how good/bad it is depends on the recording I guess.

 

A person who has years of experience in a studio will easily be able to figure out cause of the soundstage differences.

 

The soundstage/imaging differences I think are only due to our brains playing tricks on us. Definitely better though. There is probably such a small change in the frequencies (past the bass) that it's not very audible by me.

I've noticed that if you EQ down the treble a little (1.5-3db) you get a better perception of depth in a recording. This is also in combination of the bass boost.

 

The sound also almost seems like it becomes clearer and fuller. Neat! I think maybe when some frequencies drop others are boosted or just sound better (not sure).

 

Comparing the two versions without doing an A/B with two pairs isn't very helpful so take my comments with a grain of salt.

 

Based on memory (not very reliable) this is the closest match in EQ to get some of the effects of the Q701 mod with the stock Q701. To my ears the increase in bass isn't that great. It has more to do with how better it just sounds when modded.

More bass impact and it's still very well controlled and not bloated.

 

BTW I tried to increase 250hz but it didn't sound accurate at all.

 

 

With this EQ in place it's easier to hear how bad some recordings really are. Just like how I heard them on the modded Q701. Bizarre.

 

NOTE: This EQ still won't give you the same result as a modded Q701. Just a few similarities. I wish it could!

 

Believe it or not there is not much audible difference in how the treble sounds!!

How did you reverse it?  Did you manage to re-apply the stock port covers?  I stretched mine all out when I removed them  :(

 

Now I'm thinking packing tape with some microfiber centered on the back of it to cover the port.  Hopefully it won't rattle.

I used a tiny square of plastic tape and made sure to not cover any other vents. To me it sounds exactly like stock without any change.

That circle piece is not vented at all.

 

When I installed the mod back it instantly sounded clearer.

 

You can reverse that other EQ to this and it sounds close to the stock Q701. There's still better sound clarity, wider soundstage and perhaps more detail with the modded version.

Actually for some reason this EQ makes the modded Q701 sound a little more trebly than it should, but very close. We're talking like 1% more trebly :confused_face_2: Probably my ears playing tricks.

 

 

If the modded Q701 gained any extra smoothness than it's close to being inaudible to me.

 

It's amusing listening to the modded Q701 with the EQ above and then randomly clicking it off.

Once you click it off it's like you want to reach for the volume!

 

Oh yeah... the stock Q701's soundstage almost sounds like it's semi-open. It's kind of nice though.

 

EDIT:

 

Found this quote interesting. Never knew this and probably not related or maybe it is:

 

Quote:
Let’s think about sound in the natural world. If a sound occurs close to a listener, more high frequencies will be heard. The further away the sound, the less high frequencies we hear. Some engineers work to achieve depth by adding or reducing high frequencies. While this is a commonly used method for achieving depth, there are some engineers who feel that adding or reduce high frequencies to try to achieve depth sounds unnatural.

5khz is a good frequency to play with if you want to increase or decrease depth. It works wonders with speakers, thats for sure.

I already loved my Q701, but DAMN these sound soooo perfect now. Not to continue the hype, but I can't imagine liking any other headphone anymore than what I am hearing right now.

 

Good lossless music with bit perfect output to the ODAC + vintage Pioneer SX-750 receiver + modded Q701 = perfection in my book! 

 

Very, VERY detailed but also very fun to listen to. The Q701 with the type of music I usually listen to will never be great at high volume, but for low to moderate levels it's fantastic. I really don't like listening to music at high volumes anymore anyway. I'd rather save my hearing and listen at a moderate level and be fully immersed in all the detail that is hiding in the music.

I needed to say it again... I LOVE MY Q701!!! How are they that awesome?

 

I know we are kind of hyping the mod, but I think is a legit hype. :D

You guys are a bunch of deaf, self-deceiving, day-dreaming individuals.  You just messed up the perfect balance that Quincy Jones intended for the Q701.  You all should be very ashamed of yourselves and your thoughtless action.  Go have a time out in the corner.  Yes, you can listen to your mutilated Q701 while on time out.  :deadhorse:  No, not there.  That's my corner.  :)

post #3825 of 9507

^ ... and the verdict is... CULPABLE!! :biggrin: 

 

I modded them, I mutilated them... What can be next?
