The graph shows me that the ARC preamp output impedance is probably high and incapable of driving lower impedance loads w/o severe roll-off. The graph shows exactly that. Many other preamps don't suffer in this area. Many are flat from below 10Hz to well beyond 20KHz regardless of what impedance they are driving.
ARC looks rolled off in the bass region of your graph and that is precisely what I've heard in many ARC products. It's their 'house sound': solid-state with a tube output buffer to veil and roll things off.
Some like their 'house sound'. Others don't. Nothing wrong with personal preferences.
