Make way for the future....

"...Well in that case, a Integrated is also not without its compromises when compared with a separate preamp and amplifier..."

Absolutely! A good integrated does get you most of the way there though.

A useful product but one step up from a table radio. A good integrated and a great pair of speakers will do so much more. 

I have swapped a lot of amps and pre-amps but I have never replaced an integrated pre-amp section with another pre-amp. 

"...I wish people are not so quick to dismiss a product without learning first it’s capabilities. A good integrated on its own, without a source is just a pretty box..."

A great pair of loudspeakers and a good integrated to drive the loudspeakers is the first step to a really decent system. Add the source of your choice. History has shown, all in one solutions don't stand the test of time and are compromised by their design to do it all.
