Thanks guys for the advise. I plan to buy the 1.7 then do a side by side comparison after break-in of the 1.7. If the 1.7 really proves superior, then i can sell off my 1.6 which is coming off 10 years already.
Cant really go for the 3.7 as it would ruin room aesthetics, and i would never really be satisfied with the bryston 4bsst2 running a 3.7, and moving up to the 14bsst2 or other higher powered amps would cost me so much money which i am not willing to spend
I was really just hoping that the 1.7 can improve on the 1.6's detail on top and bass punch down low.
