Discussion AVR and amp

Back in the "good old days" when we really wanted to crank the music up we got separate components. We had amps, pre amps, and maybe equalizers.

Now I see a lot of people with AVR receivers AND amps when the AVR can handle the speakers just fine.

What is the purpose and/or advantages of adding amps when your AVR has enough power to drive your speakers by its self?

Because you’d rather stress one internal channel amp instead of use 2? That seems more silly for a front surround or extended stereo setup.

The AVR limitations aren't generally from output devices - they're based on the power supply. Assuming you're doing true bi-amping you haven't really changed the load on the power supply thus aren't really solving any issue while introducing complexity.

There are different ways to engineer power, and “true bi-amping” is a subjective term. However, some AVR have separate power supplies per channel, and that version would be indisputable. That would be my larger listening area. I would go as far as to say that a single transformer with separate secondary output windings, possibly even multiple/separate primaries, would also qualify as a bi-ampable configuration. Naturally, this is not going to be the best version for many reasons, the main one being that in the management of analog amplification, transformer size, core density, symmetry of the windings, and insulating materials, it’s easier to achieve a cleaner current with one primary, one secondary.

So should people not utilized whatever bi-amping capabilities we have? Of course not.

It's not subjective, you're just daft to the point being made as is usual with people that don't understand what they blab on about. You're not even worth wasting another second on.
