PS Audio p 600 or the New Premier series Better

Which one are better units Guys ?

Are the older units like the p 600 or the p 1000 Better ?

Some say that the new line is not that great and made in china

The older ones are balanced, the new ones are not. I like the older ones but the new ones handle more current. My philosophy is use an older 300/600 etc and connect devices that load the unit to only 1/2 its potential for dynamic headroom. I really feel a P-300 for sources is all you need. Use a passive device on your power amp like a Gray or something. Good luck.

Are the new ones more reliable or better to get the older one?
