It all depends on how you like to spend your time. Sometimes I just want to listen, but other times I’m in them mood to explore and tweak.
So I have 6 separate means of amplification (monoblocks, solid state power, tube power, classic, newer) 4 separate preamps (tube, SS, multichannel, classic, newer) 4 different sets of speakers plus surround, and a NOS DAC and a Delta Sigma DAC.
So how many different configuration possibilities are there? Do things sound different? What works well together? My opinions evolve.
So at this stage I don’t care about clutter; actually I love it. Maybe sometime I won’t.
One thing I will say about integrated systems: they are meant to work together, so you should get good synergies between the sections in the component. HOWEVER, if you do get the urge to explore, you may find the preamp section only mates well with the built-in amp, and vice versa, and so you can’t really convert your integrated into a separate effectively. Those extra ins and outs on integrated units are generally for convenience, not necessarily high quality interaction with separates.
It’s all just fun though.
