Relationship of amplifier sound to transformer quality?

Right, but now they will be doubled up on each channel. Or that will not change inrush?

As I mentioned before, those diode in series is to isolate both power supplies and let each power supply only charging its own capacitor.

Thanks so much for your help. Much appreciated.

If this is not just transformers, if it is two complete power supplies you are talking about combining together in parallel, then what you are really talking about is doubling the capacitance. With twice the power supply storage capacity you should notice a profound, or at least decent, improvement in bass slam, with more authority well up into the midrange. The top end may even improve. Hard to say how much. The existing power supplies being mono and separate units are already probably very overbuilt. But I have yet to see the power supply that wasn't improved by bigger/better/more caps. It is the kind of extravagant expense no sane manufacturer would ever do. But as they say in racing, run what you brung!

The transformers are not running daisy-chained. They are in parallel which means combined together working simultaneously. If I were to hook them up in series, it would double voltage instead. So yes, It will double the va rating or current capability with a slight loss due to leakage and bring C from 13,600uf per channel to 40,000uf per channel since I will put in bigger caps than oem. An interesting experiment for this kit. This is similar to paralleling an amp for increased current capability vs bridging for increased voltage or output as in watts.
