The jack is not driving the bookshelf speakers. They're active. They have their own internal amps. It's simple if you use a receiver. If someone can point me to a receiver that's more like 4 inches than 18 inches, then I'd consider that a solution. Receivers are big boxes as far as I've seen. I don't have space. Or maybe I don't want to make space.

It sounds like your speakers work for you then. On a modern TV without a headphone jack you would probably be served perfectly well by bluetooth speakers that sync to the TV. Though I'm surprised if a 3.5mm output is really that uncommon, because I just bought an LG C1 a few years ago and it has one. You can also find a small bluetooth receiver that would output to a headphone jack at WalMart.

Have a look at Fosi Audio. I'm currently using a BT30D to drive the passive speakers from an old Samsung integrated amplifier+receiver+2014-era "Smart TV" type system that died. It only has 1 analog input and Bluetooth, but it looks like they have other products in a similar form factor that can take multiple inputs (e.g. the P4 Mini). I was skeptical but needed something cheap to drive those speakers and am quite impressed.

Some of the bigness is just tradition and buyer expectation (big = expensive). But also, modern AVRs are like 1000W devices amplifying 7, 9, even 11 channels of passives. That’s a lot of componentry and corresponding heat to shed— if you open one of those up, it’s not just empty space in there like an NES cartridge or something.

... that said, there is also a small market for "separates" where you have a decoding-only preamp that either feeds active speakers or another box containing just the multi-channel amplification:

The output of these units is line-level signals feeding high-impedance loads. They could definitely be a fraction of the size they are.

That makes some sense, but for those of us with two channels maxing out at 25W each, there seems to be some use for a smaller one. I think there are more people on the small end of the spectrum than those with a big surround deployment. I suppose they're mostly using sound bars with an HDMI input.

Sonos makes this specifically. Has an RCA and HDMI input, along with being a Sonos device for streaming audio.

The only downside is the price.

Apart from Sonos in general being awful[1][2], their web site seems to be pretty bad, too. Not only is there a modal "subscribe to our newsletter" box in that link, there's also a separate modal cookie warning which blocks the modal newsletter box. It's like frustrating users is core to their mission.

And that Sonos is terrible to its users.

I had a houseful of overpriced speakers, some only 3 years old when they decided they were too old to support in their rewritten app, or some lazy crap like that.

For GP; I use some cheapo (sub $50) "100W mini amps" from Amazon. They seem fine to me.

Fosi ZD3 (https://fosiaudio.com/products/fosi-audio-zd3-fully-balanced...). Supports HDMI with CEC. I turn on my Apple TV, it turns on the TV, which in turn turns on the Fosi DAC - all connected with HDMI. The DAC then turns on a ZA3 amp via 12v trigger cable. Volume control etc is via the Apple remote.

All very cheap really. Total cost I think was about $550 (refurbished TV, second hand Apple TV, new Fosi DAC and amp). All this and I get to keep the TV in 'dumb' mode. Never even use the TV remote.

S.M.S.L. make some good ones: https://www.smsl-audio.com/portal/product/index

I use their AD-18 and really love it: https://www.smsl-audio.com/portal/product/detail/id/566.html
