Headphoneus Supremus
I have an A3, A2, and Magni3+. have tried all 3 sourced from old CD player via S/PDIF coax into Bifrost Multibit OG, and A3 was the clear winner, driving a low-impedance (~16 ohms, ~92dB/mW) planar. Tone wise, Magni 3+ paired best with the Modi3+, but that combo is easily bested by the BF1 bimby / A3.
For Susvara, which is low impedance and very low efficiency 83dB???, the A3 with Continuity would be the way to go vs Jot 1. If you are not in a hurry to purchase, at some point the Multibit DAC module (that fits inside A3 Jot etc...) could possibly get upgraded to Unison USB interface.
You could get the A3 now, without the module, and order the Multibit DAC module at some later point (as self-install, extra shipping). IMO into tougher hp loads, the amp makes a big difference.
