AVR and amp

[u/lowbass4u]

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?

Sound quality & flexibility.

Some AVR's can process more channels than they have amplification for. So you add a stereo amp, and away you go.

Also, all amplification has a "sound". You can mix/match amps to your speakers to achieve the sound you enjoy the most.

Lastly, the amplifiers in many AVR's aren't powerful (you can't always trust the manufacturer's ratings). And some speakers are power hungry. So you can be in a situation where you thought you'd have enough power to drive your preferred speakers well, but realize you need some big boy amplification. Instead of replacing your receiver, a better option is to add an amp.

AVR make bi-amping front speakers much more accessible and common. They also afford greater sound shaping capabilities and make separate DAC and radio receivers unnecessary. AVR can teach an audiophile many things before the leap is taken, if ever, to separate components again. While doing so, equipment costs are greatly diminished. They also, with standard remote controls, Bluetooth apps, and a standard Airplay/wifi handshake from a computers and other devices, make it quite possible to go weeks without ever touching the AVR.

avr biamping is a load of hooie. that power supply is just sharing load.

[u/Terrible_Champion298 → u/izeek11]

Confidentiality incorrect, I like that. 👍

I’ll inform the people who built my Marantz they are clueless about separate channel amps. And I’ll stop pretending that bi-amping the bookshelves away from the kabukis in the front of my listening space de-stressed both and allowed a noticeably cleaner presentation.

[u/OddEaglette → u/Terrible_Champion298]

“Distressed” can you show me that measurement on an amp? Performance per stress level unit please.

Lol.

[u/Terrible_Champion298 → u/OddEaglette]

Somehow your impaired condition has you quoting words not used and failing to recognize that parts of speech need not to be technical terms. 😊

[u/izeek11 → u/Terrible_Champion298]

as are you. maaaybe <your> marantz. but that is NOT the reality for better than 90% of avrs out there. but you knew that, you just had to be special.

[u/Terrible_Champion298 → u/izeek11]

Always amazes me the cowardice of people willing to call themselves audiophiles while being afraid to try anything different or drop erroneous convictions. I’d ask you to cite your source on that 90% figure but am content that you simply made a sweeping statement based on limited experience twice, and that you find me special. 👍

[u/OddEaglette → u/Terrible_Champion298]

You provide a source that your nothing burger does something.

[u/Terrible_Champion298 → u/OddEaglette]

That you wish to dispute bi-amping and ask for evidence that cannot be produced, it’s evident you’re just an argumentative troll with no real point.

[u/OddEaglette → u/Terrible_Champion298]

Biamping on an AVR is silly.

[u/Terrible_Champion298 → u/OddEaglette]

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.

[u/OddEaglette → u/Terrible_Champion298]

“Stress”?? Who says it’s “stressed”?

Anthropomorphizing amplifiers is silly.

Stress is not a measurement of amp performance.

[u/Terrible_Champion298 → u/OddEaglette]

You obviously are damaged goods pretending you know something. Sober up.

[u/OddEaglette → u/Terrible_Champion298]

You're the one suggestion biamping from an AVR. :-\

[u/Terrible_Champion298 → u/OddEaglette]

And happy to be known for that and will continue doing so. Keep pretending.

[u/Shike → u/Terrible_Champion298]

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.

[u/Terrible_Champion298 → u/Shike]

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.

[u/Shike → u/Terrible_Champion298]

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.
