Interesting. You defend vigorously PS Audio Units but seem determined to cast dispersions on Purepower. You are either a dealer, work for the manufacturer or have a hidden agenda.
I'm not defending PS Audio products. I'm stating that Jburidan has his facts wrong w.r.t. the P300 & P600 products.
I just wanted to make sure that the OP had to facts so that he could make his decision. Jburidan's wrongly stating that P300 products have a "cooling circuit" mis-informs the OP & this mis-information could/will result in a wrong decision from the OP.
The OP is free to buy PS Audio or PurePower - it will make no difference to me at all.
There is no hidden agenda on my part, not a dealer, don't work for any audio manuf.
And, you are an extremely skittish, trigger happy troll.....
