Hi hope ya'll bear with my noob questions.



So in the interest of balancing cost savings and sound quality, which should i choose? Running 100w rms speakers front and back

Option 1: Two (4x 60w@4ohm, AB class) amps total- one amp has 2x bridged channels to power the front components, and the other amp to run the rear speakers

OR

Option 2: Just save up and buy the more expensive and straightforward amp (4x 130w@4ohm, class d amp)


Also, is there any difference in sq between ab class and d class amps when hooked up to component speakers?
Thanks.
