IMO, I say just get a nice AVR or Pre-pro + Amp and forget about integrated amps.
I've looked and compared many measurements in magazines, and I think Integrated Amps usually measure less favorably than many AVR and Pre-pros in terms of SNR, Crosstalk, THD, and Power output.
In the end, they can all sound great, depending on the original source and the rest of the system.
So I recommend getting just a single AVR or Pre-Pro + Amp, instead of the Integrated Amp.
