When I had recently received the Freya and festooned it with NOS GEs (a while back...maybe 132 years?) some friends and I had a little shoot out festival with a couple of ARC tubed preamps (one was a "reference" model), a Cary SLP 98, and a VTL something...my Freya stood its ground against all challengers and amazed the gang of audio geeks as a FAR less expensive alternative to the other precious items...possibly why its in Class A now.
