Integrateds that are dual mono based perform very well, my Sim Audio 700i is a great Integrated dual mono based,. I believe the Hegel you mention is also dual mono based.
Separates vs Integrated
Hi, my current set up consists of a Coda 07x Pre, Krell 300 XD Duo. I almost exclusively stream with a Lumin U2 mini with S-Booster feeding a PS Audio Direct Stream MKii.
I get drawn into thinking a really well done Integrated could be as good or better, something like the Hegel H600. Logic being the synergy the Hegel should have outweighing the potential debatable benefits of separates. Taking out of the equation my current set up has more flexibility, assuming I would likely keep the Lumin, crazy to think the integrated would match my current set up?
