Relationship of amplifier sound to transformer quality?


Is this significant?

Bombaywalla - my apologies - the post was poorly worded.

I was attempting to use metaphors that people without detailed electrical backgrounds could relate too - I obviously failed.

My intention of using the "reservoir" metaphor was to communicate the fact that every transformer has a finite power delivery capability and not that it actually "stores" electrical energy like a battery or capacitor

But, just like a battery - If you exceed the delivery capability of a transformer, then things will happen at the output terminals of the transformer that then leads to degraded performance of the rest of the power supply and ultimately the entire component. 

Designers of quality components understand the transient nature of audio  and design sufficient "capability" into their transformers to deal with them, taking into account...
  • winding materials
  • insulations materials
  • core materials
  • Laminated vs. toroid 
  • etc..

Components built to a "price point" often have power supplies that use a transformer conforming to a more "standard design" which are often less able to match the transient demand that the rest of the circuitry is actually capable of achieving and therefore results in the component operating at a reduced level of performance.

E.G. - I 've had a couple of components that used an AC Wal-Wart "power supply" and simply replacing the Wal-Wart supply with a "more capable" transformer elevated the performance of both components significantly.

For me - Good component design starts with the transformer.

I just hope I've redeemed myself - a Little at least :-)


williewonka,
thanks much for your clarifying post. Yes i believe that you have done well to redeem yourself. My apologies too for coming down on you so hard. I could have phrased that better myself.
It's hard to know how technical the audience is when trying to explain some this material. I've found that watering it down to suit a non-technical audience can add more ambiguity & confusion rather than stating it in a technical way & later on, based on the questions from the audience, explaning certain sections using more layman analogies. More often than not the audience here at Audiogon is pretty technical & they can stomach quite a bit before barfing but one never really knows...
Your last post shows you clearly understand the virtues of a good transformer in the design of a component....thanks.
Good info guys. There are many parts in audio designs that can impact the sound. Ps caps trannies resistors etc. polite on makes good tram
nsformers as I repair counterpoint products. Significant change in sound not always but yes.  If the power supply is poor then I would not waste my time. The dad I build has a better powers supply that most amps I see.  Happy listening.
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
