Hi,

I'd like something small but decent to power my Wharfedale D225 (small speakers) and D10 (sub) I'll mount on my porch.

Any suggestions? Does any of those Chinese budget class D amps have a sub output? Not to bulky and pricy. Thanks in advance.

Regards,Christian

Also SMSL SA300. Awesome little box with an unfiltered line level sub output (which I'm using). It hasn't been measured here but Archimago reviewed it.

It's worth mentioning that the Loxjie A30, Sabaj A10A and SMSL SA300 all use the Infineon MA12070 chip. I suspect they sound similar, though I've only heard the SA300. They do have different form factors and slightly different features, so it depends what you want. The internal DAC in the SA300 is nothing special, a fact which was discussed elsewhere on ASR. Switching to a Sanskrit MKII was a significant improvement .

Given the D225 are small, the question should be "sub output WITH A HIGHPASS FILTER" and I'll wager the answer is "NEVER." I would parallel:
- From the source to the sub, which has its own crossover I presume
- From the source to a crossover to the input of the small amp. The crossover could be https://www.hlabs.com/products/crossovers/index_files/Page384.htm without using the subwoofer leg, or a little Rolls active unit.
- Per @amirm's testing (blessings upon you!) of cranking like 77 actual watts, I got the AIYIMA A07 TPA3255 for a system in a big open living room. Really nice little unit!

Bluetooth and RCA inputs

KEiiD on Amazon for $50

it’s got a cheesy connector for speaker wire but sounds surprisingly good.
I have some Klipsch RB61-II speakers and a sealed JBL Sub that I use with it and it’s fairly impressive.
