As far as the Cary SLP05, I don’t consider mine to be all that warm. It could be the tubes I am running in the balanced input sockets, or the cables I am using, or another component in my system, but I felt replacing my old Cary SLP90 with the SLP05 cooled my system down but added air & detail/hence improving imaging.
Which is not to say that I do not like my ’05, just that I am not finding it extremely warm.
