Hi,
My .7s are being delivered today! I owned 1.7s and 3.7s when they first came out, but had to sell as I downsized living space, so I do have some baseline for comparison.
However, my current room is 10x10 compared to a much larger space previously. Maybe even more impactful is my electronics have evolved from a full stack of Byston SS gear (Apple/Audrivarna sever, DAC, pre-amp, amp) to a single SONOS Connect box feeding a Bob Latino VTA 120 tube amp---kind of apples to pomegranates at best.
I'll post once I get them broken in....
Jay
