My Leben is the CS600; so little opportunity to roll the pre-amp tubes. In fact hard t find replacements.
I have rolled the power tubes and currently am running Tesla EL34's which are quite nice.
Raven Osprey 3.1 vs Leben cs600
I have been using a Leben cs600 for many years with DeVore O93 speakers. My brother who is quite a gifted musician ( mainly Trumpet but some woodwinds as well) recently acquired a Raven Osprey and cannot stop gushing about its tonality and sweetness. I would love to hear it side by side with my Leben but unfortunately he lives 2000 miles away in Montana. I wonder if anyone has had the chance to hear both of these integrated amplifiers? If so I would be interested in your impressions.
Thanks.
