I like the PS-1, RS-1, Headphile-modded HF-1 and regular HF-1. I don't like the HP-2 or Alessandro MS2i as much.
I don't consider any of these Grados to be high-end. To me, a high-end headphone needs to be highly refined and detailed, among other things. A headphone with average/low details such as the HF-1 can be very enjoyable to listen to, but it isn't very refined or detailed.
In terms of refinement and details, the Grados aren't at the level of several headphones I do consider to be high-end, including:
W5000
L3000
R10
Qualia
HE60
HE90
SR-Omega
SR-007
SR-007Mk2
4070
K1000
This list is highly exclusive. I also wouldn't include the Lambda Pro, AD2000, W11JPN, W2002, HD650 or K701 in it.

), but the GS-1000 I just can't part with.



I'd agree too, depending on what one is considering in their musical playback, they are of course high end. I often use the example that of the phones we list as top tier or even one notch below, these headphones are so far beyond what most people would think as high-end it isn't even funny. Therefore, the vast majority of phones on the board would be high-end. What is the absolute high-end? That will depend on one's definition.
