I know that the RDO194 replaces the SL2000 and the RDO198 replaces the SL3000. I wanted to know how closely the 2 matched in sound. I am looking to see if it is necessary to replace the SL3000 in my 3.1's. The improvement in my Monitor 5's was very noticeable. It made the vocals smooth not bright.
I have not heard of much differences in the SL3000 and RDO198.
Thanks for your input,
