This seems like it would be significantly better than the Topping TP22 or the SA-50 with which SMSL I think first started getting some attention. Would I be correct in that assumption?
Hey I am new to listening through speakers and am wondering how I can hook this up to my computer or tv to play tidal or Spotify since I do not have a music library I only steam music. I do not see a usb or optical port. Is this only made to habe a cd/dvd or blu ray player hooked up to it via RCAs or can I get this to work with the optical on my tv or usb through my computer?

You will need a separate dac with usb/optical support.

Get a $99 DAC from Schiit.
For those who already own the amp: Does this amp make the speakers pop when you turn it on or off?
That power brick is comically large

I have this amp and use it to power a subwoofer. Using as a mains amp yielded a very loud set of speakers, but this is not super high fi, compared to my Harman/kardon AVR310, the sa98-e is very dull sounding

Who had the bright idea to take the photo of this amp in front of the powered JBL monitors? It's gonna give some people the wrong idea....

I currently have an SA-50 for some pretty small speakers. Is this an overall quality upgrade that's worth the additional investment?
But can I drive my Magnepan 3.6 planar speakers with this amp?

Those are very nice speakers. You could probably drive them with this amp, but it's seems a shame to do so, because this amp would not drive them to the speaker's full, or even almost full, potential.
I have a question this amplifier the topping PA 3 and the new version of the indeed equivalent amp look pretty similar. Any thought to which would sound better? Thank you.
Has this shipped?
Does anyone know how this sounds compared to a SMSL Q5 Pro?
The Q5 use a Texas Instruments TAS5342 chip vs a TDA7498E used in the SA-98E.
I have a Q5 pro attached to a Amazon Echo Dot, running into a pair of CEntrance Master Class speakers. It sounds fanastic.
The problem is, I leave this setup on 24/7, and the blue digital number display of the Q5 is always on. I fear it will burn itself out over time.
Plus I don't make use of the DAC or other features of the Q5, so those are wasted in my application.
This simple, one purpose power amp seems to fit the bill better, but I am enjoying the sound of my Q5 setup so much, I'm hesitant to change it without more information on how the two amps compare.
10% THD is clipping lol

Massdrop's ad copy for this amp says 'At its recommended uses with minimum distortion, the SA-98E can drive 120W per channel'
I wonder what Massdrop considers to be minimum distortion ?
I wish Massdrop would source amplifiers for the Audiophile community that provided power ratings at 0.1 percent and 1.0 percent THD from 20Hz to 20kHz
Instead one is often left digging through technical PDF's on amplifier chips to guesstimate such power ratings

Parts Express is listing 10% THD at 60W per channel. This is probably a 20W amp.

the above PDF has technical details on the amplifier chip - figure 4 on page 11 shows stereo power output at 4 ohms at various distortion levels - from 30 to 20 to 10 to 1 percent THD - the ad copy says the power brick supplies 32V - at that voltage this chip supposedly can deliver around 100 watts at 1 percent THD - per the PDF - Figure 6 displays THD over Frequency Response but does not specify voltage or wattage - my speculation is THD rises fairly quickly from 0.1 percent THD to 1 percent THD for this chip and this amp may produce 60 to 80 watts into 4 ohms from 20Hz to 20kHz at 0.1 percent THD
Wafer efficiency? WTF?
10% THD? Ten percent?  Is that a typo?

I reject your assertion that it is the norm for Chinese class D amps. See the specs for The SMSL A2 I posted earlier in this thread.

This discussion is pretty old. From what I've read once, many moons ago Denon started using only low THD figures in their marketing. Apparently there where others also providing 10% thd figures. And it made Denon look bad for a while. In the end the market got smarter and other companys followed. But not in China. Where specs are always measured downhill. It's exactly what John-Booty says. SMSL might have figured that out the hard way and has conformed to these "unreal" standards just to not lose sales. I completely agree with you that these specs shouldn't be on this site. But if it's all SMSL provides, Massdrop doesn't have much of an option that doesn't involve them going out of their way to get some descent ratings.
Power output ratings are at 10% THD (Total Harmonic Distortion). That is really high, and it will not sound good putting out that much power. So your realistically useable power output at reasonable THD would be significantly less than the specs show here.
This is likely a fine amp if you're not asking it to output so much power.
So why is this amp pictured with a pair of self-powered JBL LSR30X speakers that do not need, nor can be connected to, an amplifier?? :)

No worries. You’ll see the amp is not connected to the speakers by any wires, so no harm done.
In fact, the amp probably doesn’t even know the speakers. They were probably just innocently walking by when the picture was taken.
Pictures can lie in that way. Just because two things are seen together in a picture doesn’t mean they know each other, let alone share the same politics or world view.
