My MC 2000 is feeding into the REVEL Ultima System and I am perfectly happy with the result. I listened to the Mac into the Sonus Faber Amati which likewise was just pure excellence. I am sure that if you don't ask for the absolute powerhorse (more than 150wpc ) the MC2000 will satisfy you at all needs and in all acustical terms. I don't trust those statements like :"not suitable for tubes". If in doubts just trust your ears!
Good luck and congrats to your Mac - it's simply a brilliant amp.
