The funny thing is, McIntosh has not made any changes to the look of their equipment. If you where to buy a brand new one today, it would look very close to the ones sold in the 70's. To me it's a hate love situation.
I used to love the old 80's Technics amps like the one you showed.

Carver amps where also a thing of beauty, you would like their silver seven, it has tubes
