Adjustable high pass filter is a game changer, and Ayima has quickly established itself as a quality brand in the mini-amps market. THIS and a starter sub and a $250-400 pair of passive bookshelf speakers would make for an excellent desktop or bedroom 2.1 system.

Odd to see the 3-way power switch with "Off, On, HPF". HPF should be a switch on the back with just On or Off

Holy cow, yes this is a rare feature esp as rsl isn't currently producing theirs.

Edit. Damnit no usb/dac. That's the only feature missing (for me) but maybe I can just rely on my external usb audio. Prefer to have as many options as possible though.

It keeps the boom boom noises from going to the smaller speakers.

Yeah, I'd just use an USB-to-RCA adapter, even something as cheap as this: https://a.co/d/0ctsNURt

No, with something like this amplifier you want to get a good DAC. Then you connect the RCA or XLR outputs on the DAC to the Amp's inputs. What you shared is a VERY cheap DAC and not something you want to pair with amplifier this nice.

Meh, I'll believe DAC price equals audible performance when I see a double blind ABx test where a $300 DAC is clearly identifiable vs a $30 one. I suspect the result of such a blind test would be similar to what happens when it's done with "fine" wines: https://www.realclearscience.com/...sting.html

The similar Ampapa D1 at $170 may also be worth a look for some people. It adds a remote, integrated Bluetooth, and dancing custom VU meters for those who care about such things. I paid $156 last December.
