Just my 2¢: I auditioned a pair of Sopra 1s using my Luxman 5M20 and a streamer/DAC as source with no preamp. They sounded very nice across the frequency range. I was listening to mostly classic jazz.
Focal Sopra n1 - mids are a bit recessed compared to Lumina IIs
I upgraded my speakers from Sonus Faber Lumina II's to Focal Sopra N1. I am using the Luxman 595 class A amp, which I used for the Lumina IIs as well.
I love the bass and imaging of the Sopra N1s. Really good! However, one thing is bothering me. The mids or vocals seemed more recessed on the Sopra N1s when compared to my much cheaper Lumina IIs. Why is this? I miss the liveliness of the Lumina IIs from having those mids more forward.
Also, when I heard the Focal Sopra N1s at the store on a McIntosh 12000, I did not detect the mids being recessed. So it's very confusing also in that respect.
