EAR 890 monoblocks versus CJ ART300 monos

Anyone hear both of these monoblocks.


Have opportunity to upgrade to ART300 at excellent price with cash and trade of one of the two ear 890 but not sure kt150 or CJ plays all types of music well.


EAR is all class A so not sure the ballsy amps can even be surpassef by CJ for all types of music.


I am not familiar with EAR but I do have all CJ electronics in my system and I am continually satisfied with the electronics, even though a number of SS gear seems to appear every now and then.  Frankly, it would take a lot for me to give up the Premier Fives monoblocks at 200W a channel.
