Onkyo 507 : ???25k-30k
Onkyo 607 : 42,600/-
607 has been reviewed in current issue of What hi-fi.
It is said to be loaded with features with a powerful sound and priced competitively.
607 is trying to follow the sucess of 606 onkyo.
Though 607 is better in all ways than 606 in features etc..but it is facing stiff competition.
It is now in competition with the new line of Yamaha recievers :
Yamaha 465, 565, 665.
these are in followup of yamaha 463,563,663etc.
