I have the rogue sphinx v3 and really like it. Another benefit of buying from rogue is that when they come up with a rev of the sphinx, they usually allow you to ship the old model back and pay to have them upgrade it. I did such moving from the v1 to the v3.
The only nits I have about its design is that you have to take the cover off to replace tubes or change the phono loading for MC. If you have it out, that is not a problem. If its in a rack, however, you have to disconnect everything and remove the unit from the rack. I wish they would build a hatch on top to make things easier.
