i need help....i have a $40 canadian dvd player..cheap i know ...but this dvd player has digital coaxel output wich i use to plug it to my harmon kardon avr 330 reciever wich gives sound to my athena 5.1 speaker set ...im all new to this home theatre set up thing...so my ? is all though i get good 5.1 sound from the cheap dvd player....i was wondering if i bought a more expansive brand name dvd player would i get even better sound...i dont care about better picture cuz i have an old tv neways...i only care about sound since i have an ok reciever an speaker set....i had the cheapest speaker wire u can think of but wen i bought good wires the sound differance was like nite an day...would the sound be like nite an day from a cheap dvd player to a good brand name also...i always thought that since all dvd players use laser they must all sound the same no matter the price,,,i could be wrong though ....so if you have heard the differance please tell me about it....
