@Electrolite Thanks for the kind words!
About the hd600 resolving a lot more treble detail against the hd58x.
I found this statement over exagerated and not true for the most part.
The hd600 has a lower treble emphasis with a peak at 3 khz. This gives a sonic cut, immediacy and presence to the sound. The sound is very clear overall. I’ll not call this a defect, but the lower treble it’s not what is supposed to be. Some people love it, some people don’t.
The hd58x is more flat in this sense, and also has more bass. Putting head to head against the hd600, it’s normal hearing a more clear sounds from the hd600.
Insted of a driver limitatation of the 58x, I think it’s a matter of different frequency response why peoples are hearing more detail on the hd600.
Anyway, the 58x bass blows out of the water the hd600 bass. It slams hard without being overdone. Punchy and deep bass is a lot of fun for music listening.
Also, the 58x, I repeat myself here, is more tridimensional and open sounding. HD600 is more closed in and uninvolving.
I guess I can call this a driver limitation of the hd600 for a 1996 design?
To me they are just different flavor and they clearly belongs to the same family of headphones.
The 58x to me, sounds like a blend between the Hd600 and hd25.
It has all the fun of the hd25 in a bigger hd600 package.
At this point the hd600 seems to me the weak chain of the family. Prior the hd58x, the hd600 was the faster and snappier alternative to the hd650. Now, the 58x beats the 600 in her own playlist.
Rock, Metal and elettronica fans will love thw 58x better than the hd600.
Slow paced music will be better suited with the hd650.
This leaves the hd600 in a weak spot. Still a great headphone and I loved my time with it. But It’s time to move on!
I still think the hd600 a bit more detail in the midrange and treble smoothness against the 58x, but as I said the difference is very minimal, and easily covered from the other advantage the 58x brings on the table.
Cheers guys!
