Are integrated amps technically better than separates?

I really love my Music Fidelity Dual Mono Integrated. I always wanted this type of British sound and level. Separates I have owned never came close to this smooth incredible power and sound. I could only afford it second hand but got it on Audiogon so was super nice. It was fun in the old days to put together Hafler and PS audio separates but that is how it all started. It is incredible how good sounding the amps are now. Love this forum! 

I remember owning a Luxman integrated back in the day. Sounded way ahead of the competition, and beautiful to look at!

Define "back in the day", please. When are you talking about, archison?

It’s so interesting that folks think they need a high quality power chord and expensive interconnects. Never mind that just inside the wall is the cheapest copper lines the contractor could buy. It’s laughable. Just inside your loudspeaker is usually a thin generic cable connection between the crossover and drivers. 
You need expensive cables because it makes you feel better. 

Led Zeppelin had high quality power chords. 😬
