TPA 3116 vs the tripaths

I have a hard time thinking of "cheap quality" but I'm new to chips... I like the looks of that amp.

Power supply?

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.

Good thing about using a 600w PS is you can power up more than one unit at a time.

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.
 
My $90 credit is with Parts Express so I'm limited to their catalog.

SMSL SA-36A Pro? TPA3118D2 chip and would leave me some headroom for a new can of Deoxit and some resistor/capacitor money.

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.
 
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.
That's great, glad it's working out for your setup!
 
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?
 
That was also common in several of the TPA3116 boards. Some preferred certain models because they had anti-pop designs.
