Unfortunately I don't really follow the portable products that much so maybe someone else can chime in. I see the Topping G5 mentioned a lot here. The Qudelix-5K is also popular here and is mentioned a lot because it has built in PEQ filters which as I mentioned is an invaluable tool especially with headphone listening. There is no good way to apply a universal EQ with iPhone and on Android it can be temperamental, so having a separate device that handles PEQ like the Qudelix can be valuable if you're planning to play off a phone in a portable situation and want to use EQ.
If you are playing from a laptop and have a 2021 or newer macbook you can just use that port directly without any other device, it has a very good dac/amp built in so you don't need another device if you are fine with wired. Most operating systems have good solutions for EQ.
Also I would say don't be afraid of these cheaper "dongle/adapter" looking products that are those USB to 3.5mm short cables with a built in DAC like the apple dongle, many of them have more than adequate power for a lot of headphones and often times you don't need to have a whole separate expensive device to get the most out of your sound. The apple (and other) dongles can be as cheap as $10 and are measured transparent here, so as long as it has enough power for your headphone (which you can calculate with a headphone power calculator and confirming with measurements on here), don't feel like you have to buy more products unless you want to. The only disadvantage to this type is obviously it does not have its own power source so it will drain your phone or laptop a little bit faster. A chinese review/measurement site similar to ASR is
https://www.l7audiolab.com/ and they have a lot of measurements of portable products on top of what we have here at ASR.
The new homepod seems pretty decent for what it is and measures decently from what I've seen. If you are not a serious speaker person or aren't prepared to spend at least $1200-2000+ to get started I would say not to worry about speakers for now, just enjoy your new homepod with friends.
