Thank you guinea pigs. I will wait for your impressions.
That is Solderdude (Frans) the designer of the Garage 1217 gear. He was planning a trip to this dealer for a while to do some measurements.
Yup. The one and only. He likes the cans quite a bit me thinks. He did a dedicated equalizer for them as well.
He has plans, I believe, to make a filter for them for the Kameleon EQ down the road. I suspect he would like to measure a pair under better conditions as he was in a dealers shop for these measurements, before he designs the filter. And yes, he does seem to like them. I don’t think he’s saying to move from the 650 if you already have a pair though, if I read his impressions right. Grain of salt on all this.
LOL! I'm browsing through Solderdude's reviews. He is quite nice with manufacturers. Some things I would bitch and moan about, he is more forgiving. Way more forgiving.
His Kameleon is an interesting concept. I wasn't aware of it until now. I know he was looking into analog equalization. He offers small modules to equalize different headphones. It's a kool concept.
Yes it is. In fact I have a prototype of the filter and a little amp he made for the old black driver HD650’s I own. Does some very nice things to those cans. IMHO. It doesn’t go very loud, which is great for the way I listen. As such, it is hard to really hear it well under meet conditions. I’ve brought it a couple of times, but it couldn’t do justice to those cans with all the noise as you can’t really crank up the amp.
It’s interesting that a completely different driver can (apparently) measure so similarly. Perhaps the enclosure has a hell of a lot more to do with the result than I had previously thought? I wonder what an HD700 driver in an HD6XX would measure like...
Looking at Solderdude's frequency response plots and comparing them to Tyll's measurements of the HD700, the similarities jump right out at you. The mini-notch around 4 kHz being a prime example. The HD660S frequency response very much looks like that of a better behaved HD700. Note that I am comparing measurements from disparate systems, which is somewhat dubious.
Here's a handy comparison for reference (along with Jude's measurements which look badly over-smoothed to me):
I remember Floyd Toole stating that the bigger the room the less it affects the sound source/driver. Since the size of headphone enclosures to their drivers are relatively small compared to speakers in a room, I'd say they might make or break a pair of headphones.
A less polite version of the HD650! As hard as it is resisting the hype... I think wait for more reviews. Thank you all who have taken the first leap though.
I would hardly classify anything on this thread thus far as hype (though there was some spirited debate on Common Core), more cautious pessimism tempered with a healthy dose of corporate skepticism and general kerfuffling.
I love this place - really helps me keep my spending under control. HD600? Magni 3? Yup, I'm good.

Might pay to read the thread first, has been posted here and discussed already. (Which is what all the discussion above your post is about, mostly)
Interesting review from solderdude. It will be interesting to compare it against a kiss modded HD650.
I wonder if they'll be an influx of 650's for sale on HF? I'll keep both for now, but it could be a good time to pick up a pair of 650's gently used. They could turn out to be "better" than their successor. Hopefully Senn will be shipping these out quickly and we'll all know in about three days or so.
Gently used HD650’s? Old news... Someone is selling a gently used HD660S already.
Well, maybe he just got them but wasn't gentle with them.
I hope there is a big influx of HD650s for sale (preferable with lower prices). I want to build a HD650K to compare against my HD600.
I'm not really familiar with Solderdude so I've got no context for his reviews, but lines like this from his listening impressions relative to the HD650...
"Mids are slightly cleaner and realistic sounding with ever so slightly less ‘clarity’ perhaps. Mids sound a little cleaner and more ‘dynamic’ and perhaps a bit ‘cleaner’."
...aren't exactly confidence inspiring. I guess the takeaway is that the mids are both cleaner, and 'cleaner'? But less 'clear'?
Looking forward to reviews from @Tyll Hertsens, @Marvey , @ManyOthersHere.
@powermatic I think that was just a typo/mistake. He's not writing for a publication after all.
Solderdue knows his stuff.
