In general, the decision to separate amp and preamp sections is to keep high power components away from sensitive lower power components. For the same reason some people prefer separate power supplies as well. It makes it much easier for designers to shield from EM fields and associated distortion.
user poll on seperates vs integrated
Hey guys, I wanted to try and crowd-source some (likely very opinionated, unscientific) knowledge. I've read about the benefits of separates (have only ever used integrated myself), and I'm wondering how those benefits compare to the benefits of higher end parts/assembly, when controlled for cost.
To put it more plainly, would you likely get better overall results from a $5000 preamp and $5000 amp, or from a $10,000 integrated, given the likely quality/components used in equipment in those price ranges.
If you're experienced both separates, and integrated amps that cost the equivalent of those separate parts added together, can you speak to which you preferred?
Thanks for weighing in.
