AKG K1000 Earspeaker Headphone Measurements
We're in for a real treat this week. Head-Fi member yaluen has most graciously shipped a treasure trove of vintage headphones for me to measure and share with InnerFidelity readers. We'll get to the sweet cache of Stax cans in short order, but I figured I'd offer up this sweet set of measurements as an appetizer.
Man, it's been years since I had a pair of AKG K1000s on my head...I guess I'm surprised at how good they sound. I think I expected them to be worse than I remember given the decades of headphone development since. But no, they seem to be as I remember: bass light, a little hard, and a bit rolled-off in the top octave; but none the less pleasant and somewhat more spacious than normal headphones. The amp I used was pretty plain-Jane, but as I recall from years ago, the K1000 responds very well to better amplification. The best I've heard them was on a First Watt F1.
Yaluen tells me this is a "bass heavy" set, but there really isn't much sub-bass going on here. I used to listen with a subwoofer in the room.
The thing I was most curious about is how the frequency response would change with the earspeaker angle. Curiosity assuaged!
Hm. As I recall I seemed to prefer the sound when slightly more than half way open, and upon relistening I think that preference stands.
Boy, what a cool headphone. If there were ever a headphone I wish would go back in production, I'd want a new Sony R10. But the AKG K1000 would be solidly in second place.
Vintage Stax coming soon. Thanks, Yaluen!
