If in doubt of the amplifier you have I would return it. The best sounding amplifier that Macintosh has in my opinion is the
MC 275. It is plenty of amplifier for the heresy speakers, I believe it has 75 watts a channel. MC 275 is considered a classic because it’s the only amplifier that I have heard from them that has MAGIC and that’s why it’s a classic. Best of luck
