Another question I’m curious about regarding this amp concerns gain. Sensitivity is specified as follows:
Input Sensitivity: 2.25Vrms - 3.6Vrms
I’m guessing that 2.25 volts is for the unbalanced inputs, and 3.6 volts is for the balanced input, as I don’t see any means of varying the sensitivity in the internal or external photos. Given the 215 watt 8 ohm power rating those sensitivities can be calculated to correspond to gains of approximately 25 db and 21 db respectively. Which seem like very low numbers for an integrated amp, and perhaps too low to be optimal with some combinations of vinyl sources and low efficiency speakers.
Yet the review contains the following statement:
Who actually needs 200 watts with 26dB of voltage gain in just the line stage followed by another x 20 amplification factor in the power stage? Very few. Because the EX-M1 hits its torque already in first gear, that number is mainly for bragging rights, peace of mind and yes, the rare customer who really does own that boat-anchor load to tap such power and gain.
That would mean a total gain of 52 db, which in contrast to the calculated numbers would be very high for an integrated amp. And probably too high to be optimal with some combinations of digital sources and high efficiency speakers.
Just wondering how to reconcile this apparent discrepancy, while having some concern that all of these numbers may be a bit extreme in one direction or the other.
