And from what I experienced with TNB power supply, that 20% is not always enough to save the day. In the end, it's still the fuses, be it in the 13 amp UK plug or the equipment it self that saves my equipment! Hence why I am not too keen on NEMA 5-15 std plugs just yet!<BR/><BR/>Having said that, I can confidently say that Pure Power is better at offering protection than most other PLCs. Whilst the Pure Power was in my system, I knew at one particular moment lightning struck, but music carried on!, with no equipment damaged. As for the intensity of the lightning? I can't be sure, but my home circuit breaker did trip.Panzerhttps://www.blogger.com/profile/06238945931494674364noreply@blogger.comtag:blogger.com,1999:blog-15183108.post-81203572454126270422009-03-30T10:47:00.000+08:002009-03-30T10:47:00.000+08:00Hi Panzer,Just two question.1.

Also did not have a chance to try them. But who knows???<BR/><BR/>Also to note, the Nordost Thor is essentially a re- worked Isotek Sigmas, with new face plate, internally re-wired with Nordost wires, and perhaps have a thing or two added in to it. Also one of the very reason I bought the Isotek Sigmas. If it's good enough for Nordost to use as a starting base, it's pretty good for me too.Panzerhttps://www.blogger.com/profile/06238945931494674364noreply@blogger.comtag:blogger.com,1999:blog-15183108.post-68667812132603826472009-03-30T08:54:00.000+08:002009-03-30T08:54:00.000+08:00Hi Panzer,Great write-up!Out of the 4 types of PLC...Hi Panzer,<BR/><BR/>Great write-up!<BR/><BR/>Out of the 4 types of PLC mentioned, may I include a 5th.<BR/><BR/>The one from Quantum called Quantum Resonance Technology (QRT).<BR/><BR/>Quantum has licensed its QRT passive technology to Walker Audio ("Velocitor"), Nordost ("Thor") and Combak/Harmonix ("Reimyo ALS-777") PLCs - all pretty expensive stuff.<BR/><BR/><BR/>How does the QRT works?

I realised much of the noise are generated by the built-in servo constantly adjusting to maintain the output voltage.<BR/><BR/>It is good to also take note that the voltage in Malaysia is NOT 240V +-10% as from April last year. We are now offically running 230v +-10% given by TNB.<BR/><BR/>The reason for the change from 240v to 230v, accordingly, there is less waste in power mainly because all electrical equipment runs better in 230V. I guess not many people know about this unless you are in the industry.kiarchhttps://www.blogger.com/profile/10492597098686032768noreply@blogger.comtag:blogger.com,1999:blog-15183108.post-80680952086744173082009-03-28T22:50:00.000+08:002009-03-28T22:50:00.000+08:00Hey guys!
