If you are looking at Nagra and Burmester, you should look at the Audionet Humboldt. Probably the best integrated, but does not include a phono. It is LARGE. If you like your double tubed McIntosh sound, any of these SS integrateds will sound different.
For an awesome preamp with onboard phono and amazing DAC, consider a Mola Mola Makua and keep your tubed amp. Don't overlook the onboard DAC; you will end up using it!
