The thread was mostly to be able to respond to the video and to share our experiences with vintage headphones being better or worse than current offerings.
I can definitely agree and see this being true to many people. HD800/(s) is probably Sennheiser’s second most popular flagship series (behind the 580/600650) and has quite a cult following as well. People will go to great lengths to correct some of the flaws in order to keep what HD800 does best, soundstage. While HD800/(s) has become the quintessential recommendation for gamers due to that soundstage, I can’t say I would wholeheartedly recommend it to audiophiles without knowing their preference. The ability to portray a large soundstage is great but at the expense of what is actually you are listening to. To have an intimate jazz ensemble become a jazz ensemble in a medium/large sized room removes me from being able to experience the intimacy of the ensemble. The emphasized upper treble and dipped lower treble can cause timbre to suffer and depending on your preference, the bass might be lacking.
HD800s stomping all over Made in Ireland 600 is very possible. I haven’t heard the HD800s but I’ve heard two different versions of the HD800 and the HD800 definitely has more of the wow factor. To me, the HD600 is probably the worst of the HD580/6x0 group. Made in Ireland also doesn’t really mean much considering all the different variations that were made in Ireland. So while I totally understand your sentiment, I would say HD600 is probably a better all arounder than the HD800s.
I think there is some experience here that I won’t touch but for many audiophiles, sound is the number one priority. Many are very crafty and can mod and improve terrible designs like the HE-6. Hifiman has always had bad build quality and that is one of the points that DMS made. Modern headphones are improving on build quality especially if you’re using something like the HE-6 to compare. However, I’d say that there are well built vintage/older headphones that are even better than Hifiman’s offerings today but yes, I agree, buying a HE-6 means you should be willing to accept that it’ll self destruct at some point in the future.
The LCD-2pf I recently purchase is definitely a testament to how heavy LCD headphones can get. If it was my only headphone, I wouldn’t consider keeping it but since I use headphones sparingly and I currently view it as a “fun” headphone, it has a spot in my stable for the time being. Comfort is another thing that DMS touched on which I can agree with. Meze or DCA or even Hifiman are fairly comfortable. However, you still have uncomfortable new headphones like Abyss Diana, TC, RAD-0, Hedd, etc etc. So while some headphone manufacturers have figured out comfort, unfortunately for some audiophiles, those manufacturers don’t have the sound quality people are looking for.
I do want to bring up that there are other vintage/discontinued/old headphones that are still worth looking into outside of those three that were mentioned in DMS’s video. I personally like the Sony CD900st that has been in production since the early 90s for asian music and vocals. I know some people really enjoy the Audio technica AD2000 for its unique mids. I’ve also been told the HD540 600ohm Gold is extremely good for string instruments. I haven’t tried the Sony R10 but those go for quite a bit. AKG K1000 is quite unique if you can find a good condition one. And then there’s the Stax SR-Omega that some view to be the best Stax ever released.
Whether you want to buy any of them in the future is totally your choice. It’s similar to my parents never wanting to buy a used car. Newer is always better right?
