M-Stage with OPA2627 SuperChip?

In the Headphonia M-Stage review he mentions upgrading the M-Stage with two OPA627s using an adapter. Well they seem to be getting hard to find, and it may end up being a bit pricey and irritating to do, but this site has their own combined chip:

Does anyone know if this would work for the M-Stage? I don't own the M-Stage yet, and this is going to be my first venture into modding so I'm a bit weary in getting this amp with the plans to mod it. I'll also be using the amp with some Grado 325is and I'm not sure what gain setting to use. If anyone is knowledgeable enough about the M-Stage to answer that question, I would be grateful.

I'm also now starting to wonder if a Schiit amp would compete well without the hassle. Hmmmm....

For better peace of mind, I suggest getting your opamp chips from authorized dealers like Digikey or Mouser. Or at least from someone whom you are certain got it from there. Otherwise there's always going to be the lingering question of whether you have the real thing or not. But as for the adapter, any source should work fine.

 

Generally, low gain works better for Grados.
