@zpl1025: thanks also for your suggestion about the Up2Stream Amp.
In this case it won’t work for two reasons:
- Like SimonB mentioned, there is also an active cross-over filter driving the 3 speakers/drivers.
- The whole system and my integration is based on auto Power On & OFF. So the system powers the amplifier only when streaming audio is coming in. When the stream ends, the power of the amplifier switches back to stand by.
Another reason is that I simply like the quality of the built-in amplifier. So I’d like to maintain that amp.
