Higher-End Class A/B vs. Class A Integrateds

I’ve been thinking about downsizing from separates to an integrated amp. I’ve noticed that some companies have both class A and class A/B amps that are both pretty expensive such as Luxman for example. Hegel seems to be well received and they’re not true class A as far as I know.

I was kind of under the impression that class A was better than class A/B due to lower distortion yet again, there are some well reviewed class A/B amps that are as pricey as some class A amps.

To be clear, it’s really not the price I’m concerned about. It’s the fact that some integrated amps $5000 and up are still only Class AB.

How do these higher priced class AB amps sound in comparison to true class A amps?

I skipped to the end. My amps drive my conventional{not horn} speakers to +90 db with less than 5 watts peak so get yourself an amp that runs in class a for the first 5 watts or so and above that we're just screamin and dancin' like a pack of drunk indians anyhow right?

My ex Gryphon Diablo 300 class A/B was outperformed by my present Vitus SIA-025 Mk2 class A and lately my Vitus was also outperformed by a Jadis DA88S KT120 tube class A integrated.

The Jadis is about the same price as the Diablo 300.

This is my experience in the past 2 years.

The only reason there are still class AB amplifiers is practical: anything above 50watts pure class A (and that's already A LOT to ask) becomes huge, extremely heavy, extremely hot, probably unreliable, and uses way too much electricity. There's just no way around it. Otherwise all amps would be class A.
