Well life never ceases to amuse me with its rich diversity, twists and turns and the ability to throw a spanner in the works when you least expect it. Only in this case a good one!
one if my big issues with any new design is noise immunity in the power supply especially with class 'd' I take great steps to try to try and eradicate as much as humanly possible from all areas of the design whether passive, preventative or obsorbtion etc
Especially with the rectification both pre and post, new full bridge designs with specialist snubber networks and ultra low noise diodes
This afternoon I have been fine tuning a new design, my new redesigned rectifier boards turned up so I populated a couple one with my usual SIC diodes the other with a set of virtually equivalent specification but with a slighter higher nano comb rating which is not as desirable but not ultra critical or is it?
Well do take into account these rectifiers do take time to settle down, well I am sat here listening to Satch surfing with alien the difference between the two indenitcally populated boards is just the diodes both the same voltage and current rating same topology, package, material both from high repurtable companies yet one is vastly superior in this application
you really would not recognise the sound as coming from the same amp, yet both are very good just one is so much more natural, real and more articulate
it it is difficult to convey the sheer difference with out actually being here in the room I appreciate this.
it really has caused me to revaulate some other designs I have currently on the go will be. Trying this out next week however this is just getting better as I am writing this
given my experience with power supplies and digital electronics it really has seriously surprised me, really need to look into this kind closely need to break out the network analyser and test beds
Given the cost and performance of the original diodes I was using it is quite something as the original CREE's are imho much better than the rest a available for the applications I have been using them in.
Never let it be said that you do not learn something everyday!
