If a TIP41 pair can do better imagine what a single TTC5200 can do. Its not really any harder to work with than a TIP34, or any more expensive.
Those chip amps can do say 3 to 5 amps “continuous” - as in repetitively. I’ve seen the graphs of SOA on the data sheets - that’s where VI limiting kicks in. It kicks in HARD. It’s not going to give you one more miserable milliamp more. A TIP41 can give you a little more - if you set the current limit up at 6 amps. If your speaker is going to demand more - say 30 volts peak at 3 ohms Zmin right in the low midrange where all the power is then you REALLY need at least a 2N3055. TTC5200 is more appropriate. Trying to dig that out of a single package with two complementary TIP41’s in it (and a hard current limit at 3 to 5 amps) is a fools errand. Reduce your required swing to 10 or 15 volts and it will be happy doing it all day. And it won’t clip.

I’ve got SS amps (and two big tube amps) that are so clean that the clip lights have to be on pretty STEADY before you even audibly notice. Whacked off solid on the scope by then.
Sound was o. K. at loud impulses. The red light showing beginning clipping. But I was surprised that a 96db Fostex is also able to consume 150 watts peak power.
1 Watt 96db
2 Watt 99db
4 Watt 102 db
8 Watt 105 db
16 Watt 108db
32 Watt 111 db
64 Watt 113 db
128 Watt 116 db
It was very loud. But I learned that also high efficiency drivers profit from powerful amps.

Two sine waves of 50 watts each consumes 200 watts of “audio power”. Do the math. Music contains a lot more than two waveforms, all of them intermittent not steady. The amount of peak voltage (therefore power) to get even 80 or 90 dB of average SPL can be shockingly high. Run a cute little 10 watt amp just to where you start noticing distortion and the SPL in the room may only be 70 dB. That’s actually sort of loud, you have to strain to talk over it.
