Hello everyone, Resolve has created a headphone target for his B&K 5128 measurement rig (which is an alternative measuring rig to the GRAS that we know that Amir uses here on ASR). Now this new measurement rig (B&K 5128) is supposed to be more anatomically accurate than the GRAS rig, but the problem with the B&K is that there is no established headphone target curve that has been created for it.......as a lot of you folks know the GRAS rig has the Harman Curve Target that was created by Harman through some proper research, (which is why it's being used currently here on ASR), but Resolve has created a target curve for this B&K 5128 and it's based on a similar slope as the Harman Curve apparently, created by applying this slope to the Diffuse Field Curve that comes with the B&K 5128 (I think he applied the slope to the Diffuse Field Curve, but I'm not 100% on that and of course I'm more than happy for someone that's in the know to correct me on that). But anyway, you can try out his EQ's to that target over here on his website:
forum.headphones.com
He's actually looking for people to try out the EQ's and provide some feedback over in that thread, so read all the instructions over there in that thread if you're interested. I thought I should bring this to the attention of the community here at ASR (some of you already know), but it could be interesting to have a dedicated thread to it, as I think it's worthy of being highlighted....plus we can use this thread as a way of discussing the target and also what we think of the EQ's - but please also post your experiences with the EQ's over on Resolve's site, as that is probably where he'd rather get all the feedback. I'm not a champion or salesman for what he's doing over there, but I did try his EQ out on my HD560s and I thought it was quite an interesting revelation, the only change I made to his EQ was to add a little more bass to it (Low Shelf at 70Hz, Q0.707, +1.5dB) - I've compared it against my favourite Harman EQ's for that headphone and currently I prefer Resolve's EQ with the small amount of extra bass that I added. To me I think the voices are more natural and without being too forward which can happen on the HD560s; I just think it's better balanced through the mids & treble, and I think the lack of a bass hump means that the lower end of voices are not "artificially" changed; I do also think the spatial soundstage properties of the HD560s have been enhanced with this EQ. Now I'm known to flip flop between EQ's when I'm first exposed to them, but usually after a week I stabalise on the one that I find most authentic/revealing/enjoyable, and I've only tried this EQ out over a couple of sessions over two days so far. Yes, so don't be swayed by my positive experience, try to listen to them without expectations, but I think it's worth trying, and at the very least it's interesting, and I quite like to see someone (Resolve) trying out some new ideas into this area of headphone measurement & Target Curves.
So far, here's the list of headphones that he has EQ's for to the new B&K 5128 Target (I think he may add some more headphones over time):
EDIT 24/3: Resolve added some more headphones to the list:

B&K 5128 Target - Community Input Thread
DISCLAIMER: The following is NOT a reflection of our headphone reference target. This is a community input thread ONLY. As many of you may know, we’ve recently moved to the new B&K 5128 headphone measurement system. There are a number of reasons for this, which can be found in this video here...
