I was told by my esteemed aerospace electronics brother (real bro, not social bro) that my idea of bi-amping using tubed electronics on the high frequencies (2440) and solid state on the lows (2226) would result in phase differences that might be audible due to the differences in circuits. Anyone concur with this assessment? I would think this would be in the noise, compared to the phase differences from crossover configuration and from driver location. Am I right?
