[QUOTE="Molnar Ferenc, post: 55607, member: 1765"] Re: Pkn 3phase-40k The FP14000 is very popular and a bit more powerful than XD6000 but only in short peaks however the average power capabilities of Lab supply are not really stronger than PKN and far older technology despite the massively sized ferrite transformer. The Lab has no power factor correction and has ugly current peaks (diesel generators do not really like it..) but has better signal to noise ratio "Class TD" idea in the Labs sometimes not so good on certain type of speakers and cabs therefore I know companies moved to Powersoft K series and/or PKN The PKN has higher efficiency due lack of lossy extra AB class amplifier however probably has higher THD. I really respect Labgruppen and their users but compared the local prices I can get almost 3x XD6000 or 2x XE6000 for a price of a FP14000 so it is not a question what we bought :-) [/QUOTE]
