Thanks for the impressions. I have one on the way. Should be here end of June. I have ER-4P with P->S, HD580 with HD600 grills, HD650 w/ 20 ft. Cardas, RS-1's. My player is a Meridian G07. My expectations are HIGH for this amp Craig (Eddie Current) is a great guy, and quick to respond to e-mails. Other amps I owned were: RSA XP-7, RSA Hornet, RSA Raptor, Woo Audio 3, and Singlepower MPX3 Slam SE. The Singlepower was the nicest of the bunch. Wish I still had them all so I could compare to the Zana
