Dear Pindac, You wrote,
" As seen from all the Mainstay Japanese Brands offering Audio Devices from this era, the devices produced as their exclusive TOTR Sale Items were typically coming with materials that were selected for their Mass and Volume.
Fortunately, It was soon to be learnt in the World of Audio Equipment, betterment was able to be attained using a lot lot less Volume and as time evolved Mass was also seen to be a betterment if substantially reduced. "
By this, are you inferring that modern audio companies are uniformly striving to reduce mass and volume? (I assume that mass means weight, and "volume" is a reference to the physical size .)
There are certainly some examples of TT makers who prize low mass and therefore also reduced physical size as a feature of their TTs, most prominently Rega, but Rega have been doing that forever. And sure, electronics that use transistors and integrated circuits will naturally tend to be smaller and lighter than electronics that use tubes, but in the area of electronics and speakers, I don’t see where small size and low weight per se are perceived as advantageous to performance. Class D amplifiers are the smallest and lightest possible per unit of power, and no one believes they as a class are superior to other types of amplifiers. Many hold the contrary opinion, in fact. So what exactly were you trying to say? Forgive me if I have misunderstood. The HX10000 seems to me to be about the same size as many 2-box high end, high cost phono stages we have today.
