I own an Atoll IN100 Integrated amp and a vintage marantz receiver 1530:
The marantz have connections for: Aux, input and output for two tapes; the Atoll have also two pre-outs, as well as Aux, video, cd, tunner.
Today I´m using the Atoll as a main amp, with Totem Arro speakers, and the marantz just as a Tunner, via the tape out connected to the tunner section of the Atoll.
My question is: (1)If in the future I decide to go to AV, can I connect to a pré amp/digital processor to both amplifiers, and use them for ex. the atoll for the front and the marantz for the rears, but making them produce the digital processed signal??
(2)I know that the Atoll allow me today to connect a subwwofer to any of the two pré-outs RCA, (can also be used to bi-amping??), but, in case of reproducing digital HT sorce, does it mean that subwoofer chanel is covered that way???
