The A90 can handle the Abyss PHI without issue. With the Benchmark I would have the volume at 100% and it was still not enough. And this was after increasing the gain via the DIP switch internally. But the Abyss is a special case. Amps designed for it have 6 to 16 watts of power. I ended up using my Benchmark AHB2 amplifier directly from the SpeakOn taps to the Abyss. That 100 watts at 8ohms became 17 watts or so at 47ohms.Now, that is a disappointment since the Abyss is not push to its potential in terms of power. Always thought the HPA-4 is also a beast when it comes to power and transparency. Does the A90 on medium and high gain provide sufficient power for the Abyss than HPA-4.
