Relationship of amplifier sound to transformer quality?

First of all, hope you are all well. Old thread but a question came up I know you guys can answer. Jim Stuart of Meridian made a comment years ago when asked about the 'lean' nature of the old Meridian 105 monos. He said what they need is a bigger transformer. The amp and psu are in separate chassis. I just happen to have an extra pair of psu. Could I connect them in parallel to double their rating? It would be a simple matter of splicing the umbilicals of the psu's and then into the amp as usual. The caps are a pair of 6800uf in each supply so I would up one set to 10,000uf and delete the other? TIA

@speedskatere,this is for ss psu.

@imhififan...So in this configuration, would it be beneficial to increase C to 20,000uf total for each psu, total 40,000uf per pair of psu? Or keep each psu at 13,600? TIA

Do you mean at the outputs of the amp/speaker connections? What value would be suitable?

I should point out I'm not interested in redundant operation. I want increased power/current/va rating

I will probably need to install a soft start?

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

Thanks so much for your help. Much appreciated.

I suppose voltage differences must be very slight. Will the power diodes prevent circulating current in the event the voltages don't match well? I suppose I will check to see how close they are before I proceed.

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.

I meant to say similar to paralleling two channels of a stereo amp or in this case a pair of mono amps. However just the PSUs paralled accomplishes the same thing.

That's perfect. Thank you.

That's perfect. Thank you.

Duly noted. I hope not. In any case, I will discover how closely matched they are first. If they are more than a few mil.v apart I think I will leave them alone and acquire a big transformer to experiment with instead. The Meridian 105s are serious world class amps even now, 40 years later. But their elegant compact form factor renders them a bit lean in the bottom end which is what consensus was back then and I'm very interested to find out what they can do with no holds barred.
