I tried other tubes and another CCS (BJTs version). Every tube has its own "sound", I tried about 10 versions of 6J5, 6J5GT, 7N7, 12SN7, 6SN7 these days - resistive load is more "colored", and IME- it`s well worth the hassle to build/use the CCS.
I described 6C45Pi sound as "on the hard, agressive and dark side", it depends of the extent of the output stage and the rest of the system (CD player, cables, speakers). But, it`s a just a nuance - warm, soft, midrange details, etc. - "signature sound" of the SE 300B amp is still there. Don`t get me wrong - those characteristics are not negative (in a sense that you can`t use/listen to it), I`m certain that some people like the sound of 6C45Pi. This is just my subjective experience, and yes, I could "live" with 6C45Pi/300B SE amp - not a bad combination.
