My Favorite tubed preamp is an AES AE-3 which Upscale Audio may still have new. The beauty of this pre is that it uses 6SN7s which are still abundant as NOS and you can tube roll many many different brands and types to find the tone/sonic you like best. You don't have to reinvent the wheel, as there is plenty of solid advice out there re 6SN7s but I really enjoyed collecting and trying them out. I don't know the Rogue pre sorry.
