"I just bought a serviced_recapped E-202.
I'm thinking to connect it only to the LINE output of my DAC, so my plan is to access directly the Amp stage of the Accuphase."
If your dac has volume control ability . Why think, just do. It takes all of 30sec to try, I think you maybe in for a surprise.
You'll hear your dac's output unmolested by any colourations that active preamps bring to the mix, that's why they all sound different to each other.
