Sold by Amazon.com, about $800.Kindly refer to the video review. My review is more technical than of the sound per se. However, I do cover the sound toward the end. In summary: Cosmetics are good, build quality acceptable-to-good for the price, sound quality is OUTSTANDING; treble A+, midrange A, bass B- but well controlled and tight. One technical issue with the balance between the left and right channels (video), could use a balance control but doesn’t have one. This is a 1 Watt amplifier (see the video), NOT 8 Watts as specified. However, all-in-all, highly recommended due to it being an excellent value for the price. Regards, Brian.
