Ha. This isnt going to put out anywhere near 600w on a regular basis, only for VERY short and rare peaks in the audio signal, and at those higher outputs it is going to have way more THD than the claimed 0.002%. Also all the "A+" in the description really lets you know this is a lower quality product.
All these cheapo Amazon sold amps use the same TPA3255 and claim the same specs and its disgusting that such blatant false advertising is allowed. I wish Drop would do some actual research on the products they allow listed here and put legit specs up, not just copy some marketing blurb and call it a day.
The maximum specs they can possibly achieve are 10% distortion at 330 stereo @ 4Ω, 1% distortion at 260w stereo @ 4Ω, and 0.006% distortion at only 1watt output. The chip isnt even capable of the claimed .002% at all. And those are just the absolute best case specs, which goes down depending on what other components in the circuit and the circuit design is.
So don't fall for fake specs listed here, and Drop do a better job on product listings and stop enabling false advertising.

EniGmA1987Not only is there the limitations that you call out, but even if you are were to take Douk's claims of power output (I'm certainly not saying that you should), this description and claims are misleading as well. Drop doesn't mention the amperage of the 48v power adapter, but per Douk's site, the $199 unit comes with a 48v/5A power adapter. At 48V/5A, Douk claims a max 120Wx2 @ 4 ohm and 315Wx1 @ 4 ohm. They also mention with a 48V/10A power adapter the max power is 250Wx2 @ 4 ohm. Their 300Wx2 claim supposedly comes from a test at 51V (no mention of amperage)

More bass!
I currently have the the HD 6XX, which sound great but, I'm am looking to upgrade the power of the bass as i really enjoy punchy low end EDM music. Any suggestions in the $200-$300 price range would be awesome.

Trying to add Topping LA90D amp to Topping A9D preamp
Any help would be appreciated...I added an amp to my streamer, dac, headphone amp/preamp system and am now not getting any music through the headphone jacks on the preamp - the specifics: Wiim Pro Plus - optical connection to - Topping D50 iii dac - TSR to XLR connection to - Topping A9D headphone amp/preamp (all worked fine as a headphone amp until I tried adding:) - XLR connection to - Topping LA90 D amp. Amp switches are set to bypass, stereo, low gain. In this configuration, I am not getting any music to either my SE or XLR headphone jacks. I made sure I switched the A9D to "preamp" and "xlr" modes. I have no idea what I might be overlooking or missing...any thoughts would be deeply appreciated! Thank you.

Mic not working pc38x
I just got my pc38x in the mail today and the out put is quiet but fine and I'm happy. But the mic will not work when on my Xbox series and I was wondering if this issue can be resolved or if the head set is not compatible with Xbox.
