Hey, i did have a good deal and decided to buy a PKN XE5002 amp but Elliot Thompson was right - at least this particular model (have read that some of other manufacturers 1U units are even louder than this one) operating too loud for audiophile listening scenario. Now i'm thinking about to replace those noisy fans with silent Noctua ones but...Noctua fans are just 1/3 of the performance compared to original ones... but do hope they will be suficient to cool down the amp because i do listen on really low levels of volume.

P.S. Sorry for double post


And other than fan noise how do you like them?

I did not want to go with class-D as it runs out of juice quite quickly and rarely is capable to sustain long bass notes. Mostly because of SMPS AFAIK and it ultra quick saturation times and drop to 50% of rated power.

That is the reason I wanted to go with LPSU with class AB preferably.


Right now i cannot answer because amp comes to me week or so ago and few things needs to be done before i can connect it to subwoofers.

Modern-day Class D Amplifiers do not offer those issues as Class D Amplifiers made 20 years ago.
