I just ordered the SMSL AL200 and I'm looking forward to testing it in my home office setup. I currently use a LOXJIE A30 with the Infineon MA12070 and the SABAJ A30a with Axign AX5689. It will be interesting to compare these setups to the AL200.
Looking at the specifications for the Infineon MA12070, it boasts high efficiency, fully integrated digital audio power with multi-level switching technology. This technology, coupled with its high power output in a small form factor, might make it a serious competitor to other amplifiers in this price range.
On the other hand, the MA5332MS multichip module offers similar or higher output power without needing a heatsink.
Finally, the AX5689 from Axign provides a digital audio converter and amplifier controller, with an impressive 115 dB dynamic range. This might give the AL200 an edge in terms of high-resolution audio processing.
