Hey Guys, First post. Need some advice on whether I would notce any improvements in sound,depth,dynmics if I were to upgrade from AVR225 to AVR630.Room size is 13x17x8.Equipment includes Ascends cbm-170s-mains,Cmt340-C,htm-200 rears/Denon-DVD2900. Sound is very good currently for both music/HT.Especially music which is about 70%,and 30% HT.I like the HK sound, thus would I reap any benefit from the above upgrade?
