These amplifiers are superb. The sound is crystal clear at all volumes, and they are built to last. I would recommend them to anybody who is looking for a high quality PA.
By accedent i test this amplifier with normal audio from CD.( I used this amplifier before only for instruments and vocals). It sounds much much much better then my Yamaha AX 1070 series. It sounds crystal natural with a great scene.
Great sound for the money. It has stood right along side my high-end amps,and has always performed extremely well. The 3-year warranty is as good as you'd get from most other makers,and there's no need to pay at least $1200.00 USD to get it!
My first impressions: Oustanding, gorgeus, audiophile sound...the price is very low for this quality Soon I write more opinions

Smooth, controled warmth, roll-off of treble (I like), very good and stable image, tight bass, with no more than a week of use...I need to run others hours more (100 to 200) for a complete review...

¿ treble ? Maybe, but I like the performance of highs.. Perhaps with a touch of treble control from preamp or mixer
