Using dcs vivaldi without preamp

How to resolve the hissing sound from the speaker when connected to the mcintosh 1.25kw power amps without the dcs vivaldi 2.0 preamp.

Hi Cenk. However I don’t quite understand your issue. I understand that you have your speakers attached to the McIntosh power amp. But you say you have it without the dCS Vivaldi which I am guessing you mean used as a preamp. So what do you have driving the McIntosh ?

Or do you mean that the Vivaldi Is driving the McIntosh directly with no preamp? If so what line voltage is the Vivaldi set to and what output level in -dB are you typically using? I assume connection from Vivaldi to McIntosh is XLR balanced?

Please also advise the McIntosh model that you have.
