Has your brother heard your Leben? Is yours the 600 or the 600x? The reason I ask is the small tubes in the 600x allow a little change in flavor by rolling the 12au7 tubes.
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.
