will a ps audio 600 power a krell kav 250 and ead tm 500?


curious if a p600 will power the amps above as well as my source components (pre, cd, dvd, sat)
thanks

Bazmataz is talking about running SEVEN channels of amplification along with an array or source components off of a supply that is capable of appr FIVE amps continuous !!! The turn on surge of the amps alone would be stressful to the PS unit in the long run.

NONE of the PS units are designed to be used with "good sized" amplifiers along with an assortment of low level components. I can see the 1200 being used with a "reasonable" power amp and sources, but that is about it. Since the 1200 is capable of about 10 amps continuous, you are talking about having only 2/3 the capability of a standard wall outlet available from it.

You MIGHT be able to do this if the amps were Class D "switchers" or something with VERY low bias, but even then, i don't think it would be enough for the power levels that he is talking about. Since Class D can run at appr 90% efficiency, the EAD alone would be pulling 450 watts by itself IF it were that efficient ( which it surely is NOT ). We are not even thinking about what it would take to run the Krell if he was "pumpin' it up".....

As such, I can't see it working with GOOD sonics or reliability by any stretch of the imagination with the equipment that he has listed. Only thing that i can say is that he better have VERY efficient loudspeakers or listen at low level if he wants it to either last or sound reasonable.

My theory is that you should add up all of the MAXIMUM wattage / current draws on all of the components that you intend to run and see what the total is. If you can't supply at LEAST that amount long term, you need more lines or a larger power supply. Anything else may tend to limit the system under dynamic or continuous high level operation. Remember, a standard wall outlet is rated for appr 1800 watts at FULL output. This does not take into account line sag or distortion.

I would suggest contacting Paul at the PS Audio Power Forum over on the Asylum to hear his take on the subject before investing any money. While i'm SURE that Paul would LOVE to sell you a PS 600, i don't think that he would recommend running all of the above mentioned gear off of it. Sean

Baz, try dropping Bob Bundus a line. I think that he ended up running an "auxillary" FUSE box off the mains just for his audio system. This offers a small amount of isolation from the rest of the house while also offering the opportunity to run dedicated lines for analogue and digital gear and heavier lines for the amps. Doing this and using a P300 strictly for the low level components would probably do wonders for you. Just guessing though, as every situation is different. Good luck and let us know what you decide to do.... Sean
