S.M.S.L DA-9 Bluetooth 5.0 NJW1194 Hi-Res Audio Power Amplifier

Not much to say apart from if you are thinking of buying this, don't hesitate :-)Inexpensive. Silly low price. BARGAIN!Excellent sound quality (amplifies what you put in without any colouring).Goes very loud if you must.Kind to the environment - uses ridiculously little electricity.Bluetooth works well.Balanced input at £200?? What's not to like.Only issue I've found is that the SMSL remote interferes with my RME ADI-2 DAC - sends commands to the DAC (volume down, for example, engages Auto Dark; volume up mutes the DAC - ironic). Still, most of the time I have the SMSL on balanced input and about 50% volume to power Wharfedale Diamond 230s. No need to use the remote as I can adjust volume on the RME DAC using it's remote (which does not talk to the SMSL - the RME is German and behaves itself).The German Infineon chips inside the SMSL are things of wonder. How they operate is a mystery. Anyway, the SMSL DA-9 is an excellent class D amplifier - highly recommended if you are using the XLR inputs. RCA works fine. Bluetooth works well.

After seeing many great reviews online, I bought one of these little amps. Wow, really impressive- does everything I need it to and does it well. Used to power my Kef LS50 Meta’s, paired with the SU-9 DAC in a lovely little 2 tier stack, the sound is clean, transparent and has great resolution. Next additions will be both the SN-9 and SH-9, as I am so sold on this line…

Connected to computer for sound playback through small pair of Ariston monitors and a Yamaha sub-woofer - very clean, full and lively sound - very impressed from such a small unit. Great to operate from control knob, or from remote. Strong Bluetooth reception.

An excellent Class D amp!!!!!!!Connected to Klispch speakers- using unbalanced input from Loxjie D30 dac

Have this paired with the SU-9 DAC running efficient klipsch speakers and sounds good. First one blew the PSU after a few hours at very low listening levels. Ordered replacement and sent damaged back for refund. Quick delivery. It’s not feature heavy but works well in this particular setup. Screen can’t be turned off, only dimmed so quite annoying in a dark room. Didn’t affect Sound quality though.Happy with it in my chosen setup

A good little amp for the money, I attached a raspberry pi to it and it doesn't sound too bad :-)

Was looking forward to using this amp as it has had some great reviews. However, on receipt of the unit it looked as though this was a return unit. The box was damaged and the remote already had duracell batteries in. When I connected the unit to my Mojo 2 DAC (which is connected to my PC via USB) I heard a ridiculous level of whine/squeal from the amp. I confirmed it was the unit as my Mojo 2 has been working fine connected to my Bose desk set-up. Additionally, the Mojo 2 is dead silent when using headphones. I followed all the set up instructions but it seems the unit was defective on delivery. Shame as I was expecting good things from it. Returned and my search for a desktop amp with sub output continues.

Particularly from such a compact Class D amplifier. Highly recommended.
