I have a pair of RTi8s and a PSW505. I will be building two - two channel tube amps (four channels in total). Rather than building the amps and paralleling the outputs, I was told it is best to bi-amp the speakers. Paralleling the amp outputs can degrade the sound quality due to nonlinearity in the output transformers (apparently).
Each amp will share an output from the preamp, i.e., one amp will get a left feed across both inputs and the other a right feed across both inputs. One amp channel will feed the low frequency input on the RTi8 and the other will feed the high frequency input. The PSW505 is fed directly from the LFE on the preamp. The other amp will be similarly connected to the other channel. The amp will be wired for 8 ohms. I am told I need to connect an 8 ohm non-inductive resistor across the high frequency input of each speaker. This needs to be done to match the output transformer of the respective amps.
Has anyone heard of this before? Will it work? Is there any downside to this?
Thanks for your help!
