Was there a SR40i ???

Super posts, thank you sir!

I was wondering…I bought a used GS1000i (the box says 1000i), but the headphones themselves have just GS1000 written on them. How can one tell if it is really a GS1000i and not a GS1000?

PS: since I wrote that I use them the least I use them excusively…crazy

 

[Johnscheley]

Since I bought an RS2e with G cushions I haven't used the GS3000 anymore. The RS has more flavor, a liquid sound and is more forgiving on the worst recordings. Right now it's my preference.

My pleasure.
(Was thinking for weeks about something like it)
Easy task:
- 8-conductor cable. The all-beloved garden hose.
- Modified rods. They are round no more squared.
- Take a torchlight: The now used neodymium magnets appear silver instead of brassy/goldish.

 

[Gippy]

I wouldn't consider any of the one-off custom Grados (like the Ariana Grande, or the Oreo, in which 50 were made for a contest) to be real models. Only ones that were available for sale to the public should count.

With that being said, the Black Label (BL1/BL2) headphones were probably the most recent rare models, as they were sold on 4OE for about a month before disappearing.

Super job! Appreciate the Grado history.

Thanks! I did reterminated it with XLR and it had 8 connector…

I have a pair of 225e's which sounds too bright with my Audeze Deckard Amp, they used to be paired with an old M-Stage HPA-1, that pairing was magic, very warm sounding amp, wish I'd never got rid it tbh, now I'm wondering will a tube amp give me that warmth back and if so any recommendations would be welcome (£100-£300), or do I grab the new 225x/325x being that they are warmer sounding and hope they pair better with my leaner sounding Deckard amp?

This is what you do, carrying the youngest Grado Fan (4 month) around in circles…, to get the wife some sleep.
As always: Correct me where I am wrong or something is missing.

SR325X use flat pad as default

 

[Gippy]

44mm = 40mm. The black ring around the driver is the difference.
