Joe Grado HP1000 Frequency Response (Anax's pair). Still a reference for neutrality, even today.

Joe Grado HP1000 CSD Waterfall Plots. Very clean, even by today's standards.

Wow... I'm still puzzled why they replaced this headphone.

While they're nice sounding headphones (although I've only heard them in meet conditions), the ergonomics are still just as bad as John Grados, which is to say awful in my opinion.

I can't get past the comfort issue on them.


That said, great set of graphs up there - no idea why the newer phones threw out all the engineering that went into these.

Joe Grado HP1000 Frequency Response (Anax's pair). Still a reference for neutrality, even today.

Just dug these ancients out after ages in storage. The stock pads have -- as typical for Grado, beyer, Senn, etc --  disintegrated (= crumbled &/or gummed up).
Haven't been thru all the HP-x mods posts yet. So ...
+++ What's the best pad option for the HP-1 ... e.g., newer Grado stock, 3rd-party (after-mkt), DIY, etc.?
+++ The MEASURED curve -- ala IEC dummy head and whatever electronics, xducers and software --  MAY be v. smooth, but who knows whether most HUMAN ear-brain systems function optimally THAT way?? ... if ear-brain could speak its mind (LOL), might it shout, "diffuse-field-eq me!"?
+++ On SQ, notice that dynamics such as snare drum are snappy quick (typical Grado) but slightly compressed (not as impactful) ... even with good amping. Not sure there is a tweak for this.

Using anything but TTVJ flat pads on a joe grado is a sin.

Never heard a pair, but indeed this looks nothing like the SR / RS and recent PS series, I like it!

love the wide, lowmid hump centered at 300hz. Flat line eq's have not sounded right to my ears for whatever reason. But neither do phones with the hump in the wrong place. The ps500's are a dissapointment partly because that hump is too low (100hz) and too severe. This graph is pretty much what i've been trying to get magnums to approach.

I wonder what these phone's graph would look like using tyll's comensation curves. I'd guess the hump would look similar, but the graphs on this site are guite different in the high end appearance so it's hard to imagine........
