I really need some infos here. How much of a difference is between my AVR in stereo mode and stereo amps like onkyo a9010, a9030, a9050 or marantz pm6005. I am asking this because i was thinking of upgrading to the new marantz sr6010 for a future 5.1.2 config, but before I buy it, I want something good for stereo with my Klipsch RF 62 IIs that I can keep for long. I dont know which way to go: Buy PM6005 using preouts on my AVR and then upgrade to SR6010? or keep my avr for stereo and just buy the sr6010. Any ideas are welcome.
