I am thinking about getting a VK-75SE. I am using arc REF7 and opera callas divina speakers which do not need so much power. There are easy to drive.
I tried the amp with arc LS15. My first impression has been the need to control the bass extension of the amp. The gain was to high. The matching was not appropriate. I do not have the chance to couple with a linestage of bat because the dealer do not have it.
My second try will be with a LS17 which I think will give a better reply to my concerns. While waiting for the second test I will be please to read your opinions about any others matching possibilities.
