Two questions – forgive me if already answered elsewhere.
1. What are the principles for maintaining physical distance between the amplifiers and source? Would it be sonically undesirable to have a phono stage [Eros], preamplifier [BeePre], and amplifier [Kaiju] right next to each other? A friend advised that one should not put the phono stage near the tonearm of the vinyl record turntable.
2. From a product function perspective, or a sonic perspective – Is it acceptable to orient the amplifiers at a 45 degree angle, or even 90 degrees [vertical]? I know you would have to account for other issues, like making sure the power cables and interconnects did not drape over the tubes or hot parts of the chassis plate, and for safety, to make sure there was no easy user access to dangerous high-voltage points inside during operation.
