Hi. Just sold my one year old onkyo 605 for £250 and added £150 for the 606. Is this a wise decision to pay the extra £150 for the 606 or should I have just opted for the 875 (silver) which was reduced to £599 at one time? I like the added features of the 606 especially the dynamic equalizer which improved the sound quality to both movies and music. Cheers!
