$58 bucks cheaper than Amazon (although the seller on Amazon gives you a 48v power supply for extra watts)

At checkout on the right side, click "enter" by promo codes. Screenshot attached.

This is sold by Fosi and it ships from a USA warehouse. If you scroll all the way down to the bottom of the listing page you can see who the seller is "Fosi Audio Flagship Store"

The only listing for the ZD3 I could find, didn't ship from a USA warehouse and I think SD only allows Aliexpress links if it ships from a USA warehouse.

Thoughts on this? I have 6 inch Kali Audio powered monitors running through a cheap 20$ dac for my living room TV, using RCA cables. I am also looking for one with a remote.

This is for passive speakers. A bigger upgrade for you would be to use XLR cables for less noise.

Fosi makes a pre- amp for active speakers, ZP3. It does have XLR outputs and even better, has an adjustable HPF. https://www.aliexpress.us/item/32...6428.html?

There's also the Wiim Ultra pre-amp which has more features and connectivity options, available both on Ali Express (if you're ok with the longer shipping time) and on Amazon (if you want it pronto and don't mind paying an extra $90 or so for that).

I have this to add two additional channels to my Denon x3800h AVR. Works great so far. This is probbaly the only amp with a trigger input in this price range.

These are so underrated. I love my micro amps. TPA3255 chipset is best in class for making clean, clear usable power. GREAT DEAL at this price. Just an FYI that you're going to want a 48v/10a power supply too unleash all of the power. I bought 4 of these when the come up on sale. That way you can buy the bare amp and save a few $'s.

I have this to drive my power hungry hifiman he6v2s directly from the speaker posts. Sound is great. Please get the 48V power supply for maximum headroom.
