Azronger
There have been multiple instances where Lord Kaan has telepathically influenced the entire Brotherhood of Darkness:
He could sense his Master's summons in the Force, and he could not resist the beckoning much longer. Lord Kaan was calling them all, the entire Brotherhood.
Darkness Shared
"I didn't expect to see your army in such sorry shape..." Qordis mumbled.
A look that might have been anger flickered across Kaan's features. Then it was gone, replaced by the beaming confidence Githany remembered. He threw his shoulders back and stood a little straighter.
"You can't judge the victor of a war without seeing the condition of both sides:' he said crisply. "The Jedi are in far worse shape. My intelligence reports that their casualties are far greater than ours. Their supplies are running low; their numbers are dwindling. We have medpacs, food, and greater numbers. And they do not have fresh reinforcements."
He lifted his voice so that it carried throughout the camp, his words booming across the tented landscape. "Now that you are here, the Brotherhood of Darkness is at last whole!"
The troops in camp paused and looked up at him. A few rose expectantly to their feet. There was fire in that single bold statement; it rekindled hope from the damp ashes of their fatigue and despair.
"The full power of the Sith Lords is now united here on Ruusan," he continued, projecting his words to even the most distant of his followers. Reaching out to them with the undeniable power of the Force, he fed them, rejuvenated them, and filled their hollow spirits. "We are strong. Stronger than the Jedi. We are the champions of the dark side, and we will crush Lord Hoth and his servants of light!"
A great shout roared up from his troops. Those who were seated leapt to their feet. Those who were standing thrust their fists up in the air. The echo of their cheers shook the camp like a groundquake.
Githany felt it as surely as the rest of the troops. It was more than just the words. It was the way he said them. All her doubts and fears simply vanished, crushed by the weight of that single brief speech. It was as if she had been compelled to obey by a power greater than herself.
Darth Bane: Path of Destruction
In the first showing, he calls them all from across the galaxy, and in the second he quasi-dominates them to follow him and erases their doubts. This is significant because it is noted the Sith numbered more than they ever had during that time:
The Sith numbers were greater than they had ever been, yet they were still losing the war against the Jedi.
Darth Bane: Path of Destruction
This means there are even more Sith than there were during The Old Republic. If one uses the in-universe opinions of historians as fact, then they numbered in the millions:
To serve on the Dark Council is to achieve the greatest position of honor, power, and influence in the Empire. Many Sith spend their lives plotting their ascension to the council, but with millions vying for only 12 seats, the competition is cutthroat.
The Old Republic Encyclopedia
As the Brotherhood is larger than Vitiate's Empire, it basically means Kaan TP'd millions of Sith, which is quite frankly a better telepathy feat than any of Failkorions; every Sith in the Empire was obviously not stationed on Ziost when he did his thing there.
Even if one chooses to ignore the opinions of in-universe historians, we still have confirmation that number of Sith involved in the making of the thought bomb was dozens of thousands of Sith, so at the bare minimum 24 000 (I know the text says Sith and Jedi, but Path of Destruction clarified there were only a hundred Jedi, so the majority were Sith):

This is nice, as Kaan dominated them all:
"I will lead the Brotherhood to the caves," he explained. "I am strong enough to join their minds and unleash the power of the thought bomb without your help. You stay here in the tent until nightfall, then sneak out of the camp. Stay safely out of view until the deed is done."
The chant was simple, and after repeating it only once Kaan was joined by the rest of the Brotherhood. They recited the unfamiliar catechism in a steady, constant rhythm. Their voices bounced off the cavern walls, the ancient words mixing and mingling in counterpoint as they echoed throughout the cave.
Githany could feel the power beginning to gather in the center of the ring, like a fierce whirlpool spinning faster and faster. She felt the pull on her conscious thoughts as they were dragged down, her awareness, her mind, and even her identity swallowed up in the vortex. The cool dampness of the cave faded, as did the reverberation of their voices. She could no longer smell the mildew and fungus growing in the hidden corners, or feel the pressure of the hands that gripped her own. Finally, the shimmering of the reflective crystals and the pale light from the glow rods melted away.
We are one. The voice was Kaan's, yet it was hers, as well. We are the dark side. The dark side is us.
Though she could no longer hear the sound of their chanting she could sense it, even as her mind slipped deeper and deeper into the center. Realizing she would soon lose both the ability and the desire to free herself from Kaan's ritual, she tried to fight against what was happening to her.
It was like swimming against the relentless undertow of an ocean's heart. She felt the words of their recurring mantra taking physical shape. They wrapped around their collective will, trapping it, shaping it, and binding it into a rapidly coalescing form.
Feel the power of the dark side. Surrender to it. Surrender to the unified whole. Let us become one.
From deep within herself Githany summoned her last reserves of resistance. Somehow they were enough, and she was able to wrench her mind free from the unholy conclave.
She staggered back with a gasp, her sense crashing over her like floodwaters bursting through a retaining wall. Sight, sound, smell, and touch returned all at once, overwhelming her frantic mind. The light from the glow rods had grown faint and dim, as if it, too, was being swallowed by the ritual. The chant continued, so loud now it actually hurt her ears. The temperature had dropped so sharply that she was able to see her breath, and tiny crystals of frost had begun to form on the stalactites and along the edges of the tiny puddles and pools.
Suddenly she realized that neither Kaan nor anyone else had a grip on her hands. They were all standing in the ring, arms raised toward its center, oblivious to the world around them. At first it looked as if they were grasping at nothing, but as her eyes adjusted to the gloom she caught sight of a strange distortion in the air.
Githany couldn't bear to look at it for more than a moment. There was something terrible and unnatural about the wavering fabric of reality, and she turned away in horror.
Bane was right, she realized. Kaan has brought us to ruin!
There was a faint tug on her mind. A gentle pull that was quickly growing stronger, threatening to draw her in with the others. She stumbled away from the profane ceremony and its doomed celebrants, squinting to see her way along the uneven footing.
Darth Bane: Path of Destruction
To be honest, that feat might also be better than anything Failkorion has, and contrary to popular belief, Kaan is not a telepathy specialist, but rather a jack-of-all-trades generalist. It is likely then that he can summon powers on a similar scale from all aspects of the Force, be it lightning or telekinesis, placing him firmly in Failkorion's tier.
Despite his strength, the Dark Lord was no expert in the rare art of battle meditation. It was one of many talents, and he had worked to develop them all equally.
Darth Bane: Path of Destruction
The relevant part comes now: Bane casually resists Kaan's telepathy (full scene omitted for length), and is stated many times to be able to easily beat him in combat:
Darth Bane, Lord of the Sith. The title was his by right; there was no other strong enough in the dark side to challenge him.
Lord Kaan knew he was no match for Bane, either physically or through the power of the Force.
Bane stayed in the position of supplication until the Dark Lord was well out of sight, then stood up and brushed the dirt from his knees with a grim scowl. He had felt Kaan's efforts to dominate his mind, but they had had no more effect than a rusted knife scraping against the hide plates of a Halurian ice-boar. Yet he had seized on the opportunity and delivered a performance worthy of the greatest dramatist on Alderaan.
Darth Bane: Path of Destruction
So Bane as of Path of Destruction might in fact be more powerful than Failkorion. This is also supported by other evidence in a previous thread of mine.
He could sense his Master's summons in the Force, and he could not resist the beckoning much longer. Lord Kaan was calling them all, the entire Brotherhood.
