Prima Luna Premium Pre

Hello,

How does The Prima Luna Prologue Premium Preamp compare to the larger tube companies like Audio Research, Conrad Johnson etc?

I was talking to a dealer who was really praising Prima Luna, their superior build quality and sound.

I am a bit skeptical as I don't have any knowledge of Prima Luna and I see they are a Chinese company.

Does anyone have experience with Prima Luna and how hey compare with the more established companies?

Thank You
