Just got Audible Illusions L1, but it sound harsh

Oh my god, this preamp is sooo revealing. I am listening Chario audiophile disc, 4th track, Memory, I can hear each breathing of the performer playing flute. I have never heard this before.
Actually, I think it sounds very good now. No harshness. And actually the Rotel RB 1080 sounds pretty good. Do you think I will get much improvement by replacing it with a DNA-1?

The DNA-1 is superior to the Rotel. Will you hear the difference? I don't know.

Apologies if someone else has mentioned this...

AI notes that the L1 inverts phase and you should swap your + and - cable connections at the speaker.

I have had an L1 for many years; this makes a big difference. If you were nice and smooth with the Rotel preamp (which almost for sure doesn't invert phase) then you would swap + and - to get nice and smooth with the L1.

Because I have no idea how much experience you have with stereo fiddling I'll just say equipment off, unplugged and give it time to discharge before connecting/reconnecting any cables/wires or opening anything up to take tubes out to clean pins/sockets.

DNA-1 is a great choice

Mallardducks is correct. The preamp inverts phase. If you haven't swapped your speaker cables you are not hearing the L1
as you should.
