Review: Great unit, feels solid - slightly let down by remote. - Sounds fantastic, very solidly built. Remote is so-so which is a shame considering the quality of the main unit - its functional though and I prefer to use the volume dial on the main unit anyway.
Review: Great AMP for the money - I use the SMSL SA300 to listen to music at my office (about 13m^2), mostly while I sit at my desk. The source is my desktop Computer plugged to a TOPPING E30 DAC. I use it with a pair of Monitor Audio Bronze 2. I appear to have received the later version o the AMP (with ROCK spelled correctly). It is more than capable of driving my speakers, and I really like the fact that the music is intelligible and enjoyable at really low levels. While the internal DAC is convinient, it is not as good as my external DAC. I do not like the sound from the BT connection at all, but I presume that this is a general BT issue rather that the amp itself. I would have preferred a cheaper version without the sub-out, the internal DAC and without the BT connectivity. Other than that: - the form factor, while it is actually smaller that what I was expecting (which is good), I would like it more if it was of similar dimension like their older SA-50 amp. - the display that stays always on. I can imagine that a future software update could enable turning off/on the display e.g. via the remote as well as when there is some interaction with the volume dial or power/input button.

## Questions & Answers

A: Yes it does

**Q: Does the remote for sa300 dac adequately and seamlessly control volume into amplifiers (such as monoblock) that have no volume control of their own?**
A: Hi, This item is actually the SA300 which is an amplifier. The DAC is the MA300 MK2 they look almost identical though.

### ⭐⭐⭐⭐⭐ Powerful sounds from a tiny box
*by M***E on 30 March 2020*

A serious upgrade from the little Denon mini system that I had been using. The sound is punchy and “full” and powerful enough to drive my 4ohm KEF floorstanders. I can max out the volume setting without deafening volume so I’m skeptic on the rated power but perfect for a smaller/medium room.. Most music genres sound good but EDM or anything with a strong beat really comes alive on this thing and also brings out midrange detail. The interface is basic but usable and I doubt I will use the remote control. I am seriously impressed with this amp - this is not audiophile money but its brought a huge grin to my face and can’t stop revisiting my old music collection. I haven’t been this happy since selling all my old Arcam kit a few years back.
