PREMIER POINTS

摘要

After reading Keith Howard's review of PS Audio's Power Plant Premier [see HFN Feb '08] I bought one. I have to say the improvements it brought were dramatic - the best I've had from a single purchase. Thank you! I recently bought a used Krell 700cx and was told by the dealer not to run it from the Power Plant Premier. I later contacted Krell (who were very helpful) who said 'line conditioning is definitely a no-no with our amplifiers'. I recal from Keith's review that he'd driven a Krell FBI from the PPP and that the results were very good. So, like a recalcitrant child asking one parent after another the same question until they get the answer they want to hear: do you think it would be safe to run the 700cx from the PPP? If so, do you think it improve or degrade the sound? There is a real reason behind this question is that the 700cx hums quite audibly when connected to my mains (which is a dedicated circuit to my hi-fi). It can be heard from more than five metres away and is apparent when the 700cx is both in stand-by and running. I experimented by plugging the 700cx into the PPP and set it to stand-by: the hum disappeared.
