Crucial phrase is to those in the trade! The information is extremely easy to find - just common knowledge, in fact - to those who still are, but I'm not sure that it is easy at all for those who are not. Perhaps it's not so surprising that audiophiles in the latter group seem to know so

From my experience, put one dimmer in a room and try to use unbalanced RCA cables of any length, and the amp will pick up the buzz from the dimmer. If you do this in your own living room, you can chose the dimmer or fix a noisy one. When I DJ, I can't rewire the room. I have to be resistant to

I think the general rule of thumb that most audiophiles make is that the input impedance of an amplifier should be at least 100x the output impedance of the preamp/source that preceeds it. For many amps, 1kohm output impedance of the Transporter should be fine, but there are many amps out there

I'd have thought what mattered is the low pass filter break point formed by the output stage/input stage [resistive] impedance and the cables [capcitance] impedance (plus any input capacitance of the power amp). Even if the output stage impedance = input stage impedance as long as the LPF break
