I wonder if anyone can help with problems I am experiencing trying to bi-amp my 4430’s.
Until now I have been running my 4430’s passive through 2 x Naim 160 stereo amps using one channel for each speaker with very satisfactory results. Recently I have introduced the 5235 crossover with the special 4430/4435 network cards installed using the same two Naim 160 amps one for LF and one for HF and am now having problems.
My first impressions on bi-amping with the 5235 were positive finding the sound to be clearer with more definition and a wider soundstage . However, over the next few days I became aware of bias towards the left speaker – which, of course, I can bring back into balance with the pre-amp balance control. Trouble is the degree of slew seems inconsistent insofar that listening becomes ‘uncomfortable’ with the sense that the balance control must be re-adjusted sometimes even within the same track . The was not necessary beforehand when running passive as described earlier, where the sound was very solidly centred - as it is now again as I have returned the system to run on the internal crossover.
It would seem that 5235 crossover and/or network cards are losing strength of signal somewhere. Or, I suppose it could be with those parts of the internal crossover which remain active when switching the 4430’s over to external crossover.
I am not very technical in these matters and undoubtedly will need to consult a specialist, but I wonder if anyone has had similar experiences or can otherwise suggest a probable cause and resolution?
