In regards to customer service... Not trying to say HSU is bad, because I honestly do not know, or sound like a fanboy of Rythmik...
The first time I hooked up one of my FV15HP's, the driver blew. Not really sure how/why, but I called up Rythmik's technical service support and got ahold of Brian who had me test a few things to ensure it was in fact dead, which it was. They immediately shipped me out a new driver and told me to keep the old one. I asked if they maybe wanted to do further testing on it to see what happened at which point they said sure, and sent me a prepaid shipment sticker to send it back. Whole ordeal only took about a week to fix.
In case your decision wasn't hard enough already.
