Icon Audio HP 8 MKII Headphone amp

[Chivas]

I bought the Grado PS1000 headphones a few months ago - it is great for soundstaging, transparency and detail (everything I was looking for and not getting from my HD650's), but must admit that they can become somewhat fatiguing due to edginess at the top end.

I am hoping a good valve headphone amplifier may improve this, but am not that familiar with good valve headphone amps and the ones I have come across look a little on the dear side, e.g. the Earmax range, which also don't receive glowing reports.

I stumbled across the Icon Audio HP8 II which seems interesting and is priced right @ £450. Does anyone have experience with this amp or similar good valve headphone amps?

Got the PS1 phonostage and i no longer have speaker fatigue in my system.
Tried a few phonos and nothing ive had gives such a big soundstage. They are basically Ming Da amps that are super tuned with good components.
The guys at Icon are great to deal with as well.

Had one of these and found it very good indeed-
