Nuforce STA200

For the Money of $499 It is fantastic value. I bought two of them on a whim about a year ago, one is still unopened waiting for ancillaries to be added If I can get any other equipment  in the house and set up unnoticed (lol), the other is teamed with a Quad Vena used as a Pre Amp listening to the excellent  Bireli Lagrene 'Standards' CD as I type and it sounds very good. All said and done it is great value at whatever the original price was ($1299)?, at $499 It is exceptional value to my ears. I could quite happily live with (and do) with the STA200. High End performance for pennies.  IMHO. Is there a better Amp for $499?

I have my STA200 paired with a Parasound Zpre2 and both have been left on for about a year+ virtually without being switched off, if so, then only briefly turned off then turned straight back on.
Is it scare mongering, or should I be worried about the STA200 going pop? I find the sound quality excellent. I actually bought two, the other is still in its box unopened. For the money $499 they are really nice sounding power amps. Don't know or care about the power rating, they sure do go loud when required. These findings are to my ears.
