As far as I can tell, the OPA1656 is only available as SOT8 SMT. But they have DIP8 adapter boards for them so you can pop them in a socket meant for swapping opamps. Otherwise it will require desoldering and resoldering. Not terribly hard with SOT8. I have 4 of them on the BTSB designed by Jhofland and just really like how neutral and great sounding they are.

X, there's also a group buy being put together for a 4Ux500mm heatsink chassis; plenty of room:
Ultimate 4U 500mm Chassis - Who is interested?

"Just been speaking with Gianluca (Modushop) about doing a 4U 500mm Chassis.

Please let me know who might be interested and we can get this show on the road.

For 10 it will be 310 Euro
For 25 it will be 250 Euro"

For reference, I am running 4U x 300mm x 25mm fins on each channel and it runs about 47C to 50C.
