It's not 1500 watts, but the TXA-1000D is PROBABLY the closest he will find to 1500 watts. I just sold one for $160 shipped BNIB.
He can get the TXA-1000D for $199 shipped from the Cadence store.
Other than that, his best bet is to find something used, but he will probably be spending closer to $200-300
Actually, they are only 75% efficient...Do those put out the 1000 they say they do?
pm senti got a digital audio monoblock dab1800x with it's orignal box. $150 shipped.
