Kclone as a power amp we used an Electrocompaniet 2 x 250, do not remember the model.
As a preamp, an Aaton Cineast and a Sovereign Director. The difference between the two was huuugeeeeee! The Tidal managed to display all attributes that made the Director a better preamp. It was absolutely SHOCKING how easily you could spot the differences. I have never heard differences between two preamps so easily.
The source was a Resolution Opus 21 and then my Orpheus DAC1!
Cables from epoch and then the famous Organic from Argento.
Kw13 the great thing about Tidal is that all their models differ only the size of the rooms that can fill. If you had ask me about the normal Contriva I would say that the only difference is bass output. But with the Contriva diacera SE I would add the naturalness of the diamond tweeter!
Just pick the speaker that fits your room and then add the Diacera option if you can go for it!
Happy Listening everyone!
