Questions from customers are good because they remind of features not yet discussed:
Why doesn't the Ergo-Ella have dual-mono power supplies like the previous Ella?
1. Actually the power transformer does have dual secondaries, both being connected in parallel to the FCUPS. This gives a very low output source impedance from the power transformer and power on demand
2. The FCUPS is set to run in virtual battery mode. It has the energy storage equivalency of about a 2 FARAD capacitor but the delivery and recovery speed of a 500h choke!
3. The point of a dual mono power supply is to avoid intermodulation effects between channels due to voltage sag. As per above you can see this is never likely to happen with paralleled HT feeds and the FCUPS.
This one single supply delivers like a fire hydrant compared to the two garden hoses of a dual mono supply.
If you already own an Ella, consider installing the FCUPS and ABS.
