I just bought the GS1000i used at a nice price, and I'm on the 2nd day of listening. I also own the SR80e, 325e and 325is, and
play my music at low to medium volume through an ALO the Island connected to my Retina Macbook Pro, playing Pure Music 3/iTunes files and Amarra for Tidal - also through my iPhone 6s and iPad Air. They've been well burned in.
Let me just say that given a clean file and source, they sound AMAZING. I say listen for yourself and don't listen to all of the naysayers!
When listening to classic rock, jazz, whatever they bring the listener in front of the original event; they are so good
they are somehow capable of time/space travel!
My other Grados are nice but give by comparison a somewhat simplified "view" through a much smaller window, with various
aspects obscured or compressed to give the effect of listening to a good pair of bookshelf speakers through a good system. The 1000i's remind me of listening to modern Quad electrostatics
- everything is just there, full life size and full bodied, warm, 100% believable, exciting....and utterly captivating.
In short and in my experience, all of the great reviews are spot on...many of which can be read at Grado's web site, (also check our WhatHifi's).
For me, these are end game phones.
With low to medium volume listening - I'm not into listening loud - they give me total, immersive enjoyment along the lines of a $100,000+ world class sound system.
