Hi Rinpoche, in the Rowland field, there is also the Continuum S2 integrated. I ssuspect its cost in Canada might be 60% to 65% of M625 S2. CS2 is an absolutely marvellous sounding amp... Approximately 400W per channel. I heard it several times at RMAF and it is incredibly musical and resolving. You can either feed your Aeris in its line level inputs, or bypass the built-in Capri S2 linestage circuit, and feed Aeris directly into the amplification stage inputs.
Here is Roy Gregory's review of Continuum S2 on The Audiobeat:
