Love my Melody I880 integrated. Uses four KT88s and one D100 power rectifier tube, has 50-60 wpc with excellent bass control, beautiful midrange, nice clean top end and wonderful imaging. Used these should be well under $2k. Killer good looks, quality point to point wiring, sound quality way out of its price range. Highly recommended.
