On the Berlin II mini monitor
I connected Berlin II with extraordinary Audio Note KEGONS Low Gain version monoblocks delivering 22W matched with Audio Note preamplifier M8, the 86dB efficiency of Rogers LS 3/5a that construction is rather adapted to push-pulls, do not really let listeners enjoy the outstanding SET monoblocks signed by Peter Qvortrup of Audio Note. Nonetheless, while the set Rogers-Rogers plays very well high and middle frequencies referentially, and mid-bass is reach (at least, according to the ear of English traditionalist), AudioNote-Berlin II set plays referentially and emotionally to the full extent of frequencies (the only limit is the size of a room I have a living room with quite big capacity!). A combination of AN and Rogers LS 3/5a does not make any sense and Berlin II with Rogers shows clearly difference between SET and push-pull configuration. And as it is not to me to judge if apple is better than pear, Berlin II mini monitors are able (providing honest court proceedings) to resolve an eternal, audiophile conflict (SET or push-pull).
