100+ Head-Fier
Let me just say that the Mojo's bottom weight is not lacking. The issue that may be heard with passive speakers is the amplification requirements, not the source requirement. The Audio Bronze 2 speakers are rated 8 Ohm, 90 dB/1W@1M with an amplification requirement of 30-100W of power. The speakers just aren't sensitive enough to be driven without a power amplifier. That's not an issue with the Mojo, that's a system mismatch.
If looking to use the Mojo in a system make sure the system is matched properly for power and then adding the Mojo as a DAC will not, in any way, show a lack of bass or tonal mass. That 'rumour' is unfounded.
I thought that the sensitivity rating on these Bronze's was pretty high, let's say compared to the LS50's which people earlier were suggesting for use with the Mojo in a dedicated home setting. I don't know a whole lot yet on my learning curve but when you say "aren't sensitive enough to be driven without a power amplifier" (in your first paragraph) I will have my Cambridge CXA 60 integrated connected. If I'm not understanding you, please correct me - my green horn is heating up.
