symphonic Line RG4 III vs RG4 IV?

Bombay,

i did own Rg1 MKII which used Toshiba output transistors in Mk II and also owned a RG1 III which use the Sanken transistors in the Mk III. I feel MKIII has slightly better bass and sound stage is better but did not notice the midrange? However, they always sound the flavor of symphonic Line.

dear Gregm,

I saw the RG4 IV, but not sound or music from it.
from your comparsion, maybe I will prefer the MKIII sound. A local dealer told me, SL is changing its sound due to change of designer? is this true? thanks

Tim
