This is a good raised question since I was also analyzing +s and -s for separates v.s. integrated. Designing an integrated amp there is only a minimalistic need for the preamp section that must not even have a positive gain or even have it passive. No need for extra- pair of interconnects.
Tube pre- and solid state amp integrated designes are plenty as well so I don't think that the statement of Philjolet is the reason.
Just by banal view have anyone of you seen a high quality integrated 300W/ch/8Ohms? I didn't...
In case with SS design for both parts there will be a huge deal of space needed for heat dissipation along with heat influence on elements of both amp and preamp section. Power supply issues are also bring a conflict between two parts in one amplifier.
In case with tube-pre and SS amp in one integrated there will be no heat influence on tubes since tubes are not affected by the temperature changes but they're even more affected by the power supply conflicts.
Nowdays, there are quite a-bit integrated amps that realy do make sence but if you have sufficient enough power for your speakers.
