ckr1969,
Oh I forgot to mention the differences weren't huge and the 218 is a very very good sounding amplifier but when a $22,000 amplifier sounds better that's saying something about the new MDCA circuitry that sim audio has developed.So why spend $50,000 on an amp when you can get a better one for $22,000, and let's just say to your ears the 218 sounded a little bit better that doesn't justify double the price does it?.
