    Yes, that should do it.

    The amp comes with a lower voltage 14.5V 4.5A power supply, so you can try that out first - it may be all you need for your purposes.

    You can get a little more performance and output wattage from the TPA3116 chip amps at higher voltage and more available amperage.

    19-20V seems to be the sweet spot for maxing the sound quality, buy they run fine up to 24V.

    I have owned one of those and I was very impressed. Good sound, nice build quality, no quirks. I would recommend it though there has been some discussion about the latest batches not using the 3118 chip.

    The 350W ps I have supposedly has a heat triggered sensor for the fan.
    If my eyes don't deceive me, you have a TI TPA 3251 module....which implies that you're using a 48V 12.5A ps.
    Do you use a step-down converter to get lower voltages off the unit in order to power other boards?

    The PS I have is the 36v version. Can be adjusted up to 41v.

    I stand corrected then. So a 16.5A model, or there about.
    That's actually very helpful since I would like to run two boards off one ps.
    An option I hadn't considered.
    Thanks for the reply.

    Correct. 16.6 amp. I just bought another one.

    I would get the SA-98 out of SMSL's lineup https://www.parts-express.com/smsl-sa-98e-tda7498e--stereo-amplifier-2-x-160w--230-214

    I've had a tda7498 chip amp before, and really liked it. Definitely more powerful than the single chip tpa3116 amps, and very noticeable in the bass.

    For those of you waiting for the Allo Volt + D, the board without a volume control, I recently got an e-mail that says they've approved the board design for manufacture and the likely date of release will be some time in March.

    Dunno if it is system synergy, but my impression is that the Nobsound dual 3116+ seems to me sounds more lifelike and dynamically 'immediate" than the new FX Audio amp. Bottom end also seems to have better definition. Needs more listening, I suppose.

    I've had the Dayton DTA3116HP hooked up all week and I really like it. Pandora>Dragonfly Black>Dayton>Mission MS-50 speakers.
    Plenty of power for a desktop amp.

    Still with the stock power supply, I'll report back when I upgrade.

    Thank you.

    I got my sure Electronics AA-AB32191 2x300W TAS5630 with Meanwell power supply and I'm getting a pop when powering down. Any ideas what could cause that?

    Mine does the same thing. I just mute the speakers.

    That was also common in several of the TPA3116 boards. Some preferred certain models because they had anti-pop designs.

    How does one mute the speakers coming off the amp?

    Or a better question, how does one determine if the popping is dangerous to the speakers?
