Have things progressed since last year ? would an LED driver be worth trying out ?

I don't need very much power, a lower current might well suffice. For example, I'm currently using a 1W tube amp. At this power level I don't need much above 500mA for SE Class A.

e.g. http://www.recom-international.com/p...ine/RCD-24.pdf

Nevertheless, the idea presented in this thread is very interesting - I have 4 boxes that were destined for SE Class A which were never finished because the heatsinks weren't 'man enough' - the switching current sink might be my way out...

It depend on how fast that LED driver could manage the voltage changing (slewrate) it seems that devices using some output capacitors.
