Thanks for the graph. That is a nasty dip at 4k.

Indeed, but this leaves me interested in the 'no felt, stock velour pads' graph...

This is the graph Velour K240 on EVO with no felt vs stock leather EVO with no felt in front of driver, the velour seem to make it sound a little bit better:

IMO, the velours pads (AKG 240) give the midrange more presence, especially the vocals.

With the pleather pads, the mids are almost a bit recessed (not the higher mids of course).

Looking at this thread - seems to go same way as with HD681, lots of modding. Makes me wonder why not to buy cheaper HD681 and add working/proven Frans mkII filter & akg velour or custom pads and get better sound than EVO? I gave up my hopes on EVO and ordered another pair of HD681, going to make wood version of this after my HD662F wood redesign.

Audiohipster made good on the EVOs and shipped me a working one. All is well.

With or without the felt, Evo has much more subtle high than 681 which make it sound less harsh and more pleasant, that also mean you dont need to mod the filter like 681, not everyone has soldering skill to do filter mod. The dip at 4khz is very small and dip is harder to hear than peak so it not that bad, i didnt see anyone notice it until we saw the graph. The filter mod for EVO is to reduce bass to make it sound more balance but it's totally uneccesary for almost everyone, just for who want a more balance sound, beside the 4khz dip, EVO and original 681 sound very similar, so you can't really tell 681 is better in sound quality than Evo. In conclusion, at 50$, you get better design, more easy to use (2 different length cable), very good velour pads, good sound quality out of the box, doesn't need modding so i think EVO has very good P/p, just like original 681.

Well, opinions are different. When you read rockgrotto forum and other impressions, ppl seem to like hd681 with mkII filter better than EVO when it comes to sound.
EVO stock cable is pretty "crap" like stock HD681. Needs changing.
EVO stock pads are better than HD681 pads but also should be changed for better ones. Needs changing.
EVO harsh highs are "hidden" with felt which many find too "muddy" sounding. If they are removed the highs peaks are back like stock HD681. Needs modding. Although, I agree, it`s lot easier to mod than soldering filter, not everyone can do it.

 

For me it`s cheaper to go with HD681 and mod it. Filter components are dirt cheap and made my own pads which are lot better than stock (and I belive better than AKG velour), also dirt cheap. For me, only bonus with EVO is the design.

As far as I`ve read about EVO impressions It seems that if you want better sound and don`t care about looks, go for HD681 with filter and AKG velour (or custom) pads. 

 
Not saying that EVO is crap and don`t buy it, opposite - it`s definitely great bang-for-a-buck cans. Just that for me it`s easier and cheaper to mod HD681. Seems to be matter of taste in the end.

I read rockgrotto forum and i only see that Rabbit and Frans have both EVO and 681, Frans didn't listen to the new EVO, Rabbit said that after remove the felt they are almost identical. In other forum, the impression is quite mix, 50% prefer EVO, 50% like 681.

I recabled 681 with canare cable and it's quite a improment but not very big, if it's crap than every headphone cable under 150$ is crap too

I think the better pads you a refering to must be some type of J $ pads or Alpha pads. The velour pads come with EVO is very good, as good or better than the AKG K240, no need to change.

If you already read the thread in diyah, you must know that EVO without felt doesn't have the peak like original 681, EVO without felt have the right high frequency that a original filtered 681 aim for. They are different, EVO is not a original 681 with felt.

If you are type of modding guy then i agree original 681 is more P/p but other than that i think EVO is much better for everyone else.

Some mods were required when the headband gave in and snapped in two...

I cut and glued some scrap leather (we have heaps of this in our basement). The photos are not super clear as they came from my phone, but the leather looks sweet and works well.

I would totally consider buying the original HD681 if I could get them plus pads for the same or similar price, but if the original HD681 is better I'm sure my ears can't tell the difference and they do end up costing the same so looks do count...
