in my opinion jvc has done very good audio gear , i have his cousin RX550V plus KD-V66 3head deck from this family , both sound amazing , i really like them ..........receiver has lcd display lighted from behind by lightbulbs , 7 band eq with his own display , unfortunatelly bars are fixed not spectrum style, i had a heating issue with 4 little transistors-2sa1666 mounted on tiny heatsinks they work as power stabilizers i think, after hours of listening cover was really hot , solution was a cooler fan 6x6 cm mounted nearby his job is to recirculate inside air without any major dust , now it run for hours with a little warm ......JVC has done a little trick with their amps , they put SEA EQ wich improves sound quality a lot especially on budget speakers , especially when your room or speakers position dont help u to get best frecvency response, that is why most their amps sound good in almost any condition.
