Agreed. T50RP still has more soundstage than most orthos because it is circumaural and the cups are deeper.
It can get away with this because the driver is still much larger than the small stuff like the ones in the Yamahas and the SFI drivers, even if not as big as the first generation Fostexen. smeggy has proved that, with enough modding, these will be much better than most other orthos.
smeggy, did you make the cups angled on the inside, or are my eyes playing tricks on me? They look very nice, and amazingly quite a bit of it is from the original.
First generation Fostex: T30, T50, T50v2: ~62mm
Second generation Fostex T20 and T40: 45mm
New Fostex T20, T40 and T50: 35mm square driver
Yamaha YH-1, YH-100: 55mm
Yamaha YH-1000: 50mm
Yamaha HP-50, YH-2, YH-3 46mm
YHD-1, 2, 3 and YHE-50: 38mm
ATH / SFI: 38mm
So as you can see new Fostex drives are tiny. I was very surprised how much bass they have
