I'll play too.
In a hi-fi show in 2017, went from room to room listening to the set-ups, as you do, some you like, some you don't, you know how it works.
And then .... BANG!
I entered the room and was flabbergasted.
Focal Sopra No1 powered by Mola-Mola Kaluga (NCore NC1200 mind you) monoblocks.
I will never forget that sound.
I was just standing there, paralyzed.
PS1 €8,100 for the speakers + €12,000 for the amps = €20K. Save some change for source and DAC.
PS2 In the same event I was really impressed by Spendor Classic 2/3 speaker powered by Exposure electronics. That would have been my choice if it wasn't for the Focal / Mola Mola combo that blew everything away.
