Hello fellow enthusiasts,
I recently caught the 2-channel bug in a big way and I am in the process of putting together my first true "high-end" 2-channel system.
My DAC/Pre is the Berkeley Alpha DAC Series 2 and I had previously been using it with a Parasound Halo A23, driving the A23 directly via the Berkeley balanced outputs. Speakers are Focal Electra 1038BE. I have sold the A23 and am in the process of shopping around for a new amp to be used with the Berkeley driving it directly.
My question is how do I go about matching the balanced output level/output impedance of the Berkeley with the input sensitivity/input impedance of any particular amp? The Berkeley specs list it as having a balanced output level of +12dBu recommended and +18dBu maximum. There is no mention of an output impedance.
What specs should I be looking for in potential amps to ensure they will mate well with the Berkeley?
I have my eye on a McIntosh MC452 which is listed as having 4.2V balanced (for rated output) input sensitivity and a balanced input impedance of 22,000 ohms, but would this be a good match with the Berkeley?
Assuming that +12dBu is 3V and +18dBu is 6.1V -- and the McIntosh requires 4.2V to reach maximum output, but Berkeley recommends +12dBu or lower, is this a bad match or am I mis-understanding how this all works?
Why let facts or common sense get in the way of your opinions.
