Would anyone happen to have experience running a Yamaha Integrated amplifier with the original Klpisch forte'? or even Marantz I have my eyes on these models Marantz PM6005, Marantz PM5005, Yamaha A-S301, and the Yamaha A-S501. Which would sound best with the forte? if at all, and would the 45 watts even be enough if i went with the Marantz? if neither of these would be a good choice it would be greatly appreciated if someone more experienced than myself could recommend a different make. but I have a $700-$800- budget rather stay around the $500 mark, opinions and recommendations would be great! let me know what you guys think.
