Review: Ok okay ...don't expect more...ideal for casual listeners - Don't expect much with all the positive reviews...you need to have good quality speakers and it can't pull 80w speakers also...as someone mentioned.... False marketing specs... Quality will be good with good dac and pre amp ...Ideal for 30w-40w speakers and 50 w subwoofer... Don't expect punchy bass .. for this price range it was a good one...I am using 18v 20A power supply.
Review: Cheating product - Do not buy this... Its such a bad experience to me, sounds shows may be 15 to 20 per channel only. Please don't buy
