Site maintenance in progress, some wonkiness may ensue. Thanks for your patience.
Thanks John, I'll look into it!The reason I ask for these regulators is that people report the Hypex amplifier modules with them fitted sound quite a bit better, and all those regulators do is provide power to the op amp before the actual amplifier. So I imagine this would be an easy was to improve the performance in a lot of gear by simply switching out standard regulators for the HxR ones, since many, especially the modern op amps seem to be quite sensitive to the quality of the power they get. But the regulators don't seem to be availible seperately...
But those are not regulator parts but whole PSUs on PCBs, aren't they?
The Hypex class D amp modules spec out very well without redesign effort. http://www.hypex.nl/docs/papers/ncore%20wp.pdf Looking at a recent white paper by Bruno, shows 2 tone IMD down >100 dB which strikes me as quite good.
Does anyone here know if these can be bought seperately or if something similar exists from other manufacturers to be bought? Seems like a neat way to increase op amp performance from what I've read.
looks like the sjöström links are outdated because the site has changed as bit over the years. start here: http://sjostromaudio.com/pages/peranders, no need to be shy, isn't this your company?
