I had the scm7 v1 Sachin, so my comparison is based on that (and of-course based on my memory as I don't have them any longer)Would love to read your comparison of the two young guns - the SCM7 and the 3/5.
Though both speakers are roughly same size in cabinet volume, they are entirely different. The scm7 is made of a solid, hard cabinet - and weighs much more because even the drivers weigh a lot, and sounds quite neutral. Due to this cabinet rigidness it behaves like there is no cabinet at all and totally disappears throwing a huge, wide soundstage with precise imaging with superb resolution of details.
The 3/5 on the other hand is a thin walled cabinet, that has a sound signature veering to the warmer side of neutral. Is is tonally richer, but cannot match the scm7 in sound-staging and imaging. and some details are obscured. However due to the tonality it is perhaps more musical sounding.
One has to choose which option they would prefer I guess. I still have the scm 19v2 and generally what I stated for the scm7 applies, though the v2 versions - new tweeter is more refined.
Cheers,
Sid
