Oh one last thing. Did the modded K712 and stock pads have way too much bass or did you just check it with Q701 pads?

 

 

I don't think you'd like the HE400 as the mids are a little recessed. HE500 is better in that regard (I've heard both).

Since the mod only adds a little more bass, no - there isn't way too much.  It's not like they were were borderline basshead cans. :p

It's worth wanting...

I have the he500 and its my favorite. Q701 use to be my favorite until I got the he500. The Q701 was placed in the back burner until I modded them a week ago. Now I have them both out. Both are great and are being ran off a lyr.

Good to know! That puts the modded Q's in a really good position! Not saying that they are the same technical level, but that they are enjoyable at the same level at least. :D

I just tried the variant of the bass port mod where you have the tape removed, but pack some foam in the holes and I have to say I like this better.  The impressively low frequencies produced with the port wide open were giving me a bit of a bass head-ache and the soundstage was crazy wide.  Not sure why... just felt like there was pressure on my ears whereas with 2-channel stereo speakers, I usually like a little properly leveled subwoofer action in the mix, but I think headphones might produce too much direct SPL on my ears at the lower frequency extremes.  It also did sound a bit loose.  Maybe this is what AKG was up to for comfort over a long listening session, but over-did it a little on the damping.

 

With some porous, compressible foam I cut from a foam roller designed to curl hair, I was able to pack two equally-sized pieces into the ports carefully using a Mit Tools pick and I think this is the un-EQ'ed balance I was looking for.  I'm now experimenting with the outer foams (under the Q badge) to get my soundstage width exactly how I want it.

 

The Qs are sounding great over here on my Nuforce Icon HD with these adjustments, but I must agree with recent posts that I was impressed by the ODAC I heard at a meet a couple months ago as well... for less money.

Glad someone else is digging the foam mod :smile:  Did you actually work the foam into the ports, or just cover them?  With mine, I did the latter.

 

One thing to consider is what Frank at AKG's US customer service mentioned during our conversation.  The Q701 is supposed to be a studio reference HP, which he likened to studio monitors.  He said that doesn't necessarily translate into a home listening environment (bold is my interpretation of his overall point).  I have to believe their engineers + Quincy know what they're doing and what they wanted, and achieved that.

 

That said, I definitely appreciate them more with the foam mod.  Now I'm eagerly awaiting the Anni/K712 pads, and the HiFimeDIY Sabre U2 Asynchronous USB DAC and USB isolator.  I was really tempted to get the ODAC, but the HiFimeDIY DAC has a new USB receiver that will also handle 88.1 kHz.  That, the price, and lots of positive reviews clinched it for me.

One other idea is to use 3M Micropore tape found at any Walgreens. It's a tape that lets some air in. Not sure if it would work or not.

This is probably what I would try for the stock K712.

 

Here's what the stuff looks like:

You have to be careful with that port because it goes straight down to the center of the driver. Any dust that gets in there may be a problem.

post #4134 of 8180

I just crammed it into the port using the MIT pick.  I was careful not to actually poke the back of the driver with the pick.  Unfortunately, this is probably not a consistently reproducible mod to implement, but there is no tape, which I was wanting to avoid any potential resonances from although that was probably being paranoid.  As Thurston pointed out, there are many types of foam densities out there.

 

It's in there well enough to not come out after several hours of listening, lately at volume levels louder than I should (tsk, tsk!) because bass is tight and punchier than stock without the excessive lower end and things sound slightly clearer yet without the EQ processing I used before to increase bass.  The Q's midrange is more forward without EQ, but I'm getting used to it.  It's definitely ruthlessly revealing now... starting to get that "good tracks sound amazing, bad tracks make your ears twitch" thing going on.  With EQ, the sound is muffled and smoothed out just enough to not sound so intense, which is definitely good sometimes.  I guess when you have this kind of "problem", you have an adequate listening setup that should stave off upgrade-itis.  Now if everyone would just stop talking about those HE-500s all the time!

I think you did a great buy and I am eager to listen about your experience about it!!!

post #4137 of 8180

I still can't come up with anything negative to say about the bass hole mod. I'm listening to some Fusion Syndicate right now on them and it is amazing. I am on the list to demo the Alpha Dogs, so I will be comparing the two once it's my turn. I am in love with my Q701, but we will see if the AD can knock it off of it's throne

I'm glad you mentioned the Sabre DAC, as that got me researching.  I didn't realize the ODAC uses the same DAC, so that was encouraging.  I'll definitely post some impressions in a week or so.

LoL
I think the Modi uses a Sabre branded DAC too? Implementation is part of the story too, of course.
