In the mid 90's I purchased a Harmon Kardon AVR 25ii. This system has performed fine for me but is obviously outdated with connections and hook ups. Additionally, it's only Dolby Digital 3.1. I am interested in a modern amplifier with up to date connections and more channels. Over the years, I understand that sound quality has diminished, per price point, because of company budgets and paying for licences. With this in mind, what would a modern amplifier, similar to my Harmon Kardon's sound quality, cost today? What should be my budget? Thank you in advance for your responses.
