Influencer Sound Opinion

D90 is fast, articulate and it hits like a train when it's needed. It doesn’t roll-off sub-bass information and my usual pugilist music as electronica and rock started throwing punches at me, I finally felt a crazy amount of energy and impact. Finally, I can listen to my rock without feeling that something is missing from my music. In this respect, D90 is sounding like a grown-up, balls to the wall DAC with authority has its chin up and knows to impress a music aficionado like myself. Finally, an AKM based DAC with a slam, speed, and impact, the end must be near for sure.

Sub-bass was always fast, light on its feet, struck hard and gone deeper into the mix. Sub-bass performance is actually very good…. Everything down to 30 Hz notes was felt with my entire body, it’s deep-reaching, layered and detailed but also controlled without any flabbiness.

Mid-bass performance is not elevated, like how some other units are doing in this price range. It is super linear but defined and clear sounding. There were multiple times when I spotted bass layers that hit me like waves on a shore, nothing to complain here.

As for midrange, I’m glad that TOPPING didn’t go for a V-shaped sound signature as SMSL did with their M500, D50s, by comparison, is not shy in showing off all those mid frequencies at their best. When the tracks asked for a smooth and musical midrange, D50s delivered plenty of those. When tracks demanded a technical and deep-reaching midrange, D50s was able to be technical without being clinical.

Treble is extended to the sub-sonic area; everything is outlined and revealing. The usual suspects like cymbal crashes and double drums carried a lot of energy, sounded clear with a sharp outline. Treble wasn’t clinical or bright or something like that, just extended yet never harsh on the ears.

Influencer Conclusion

“I am not that easily impressed when it comes to audio sources, I evaluated more than 20 audio sources last year and out of all of those, probably only 3 of them created goosebump moments for me. D90 is sounding easily in the top 3 DACs I tested at my place at any price point. It sounds so familiar and yet so different compared to other delta-sigma designs that I don’t know how to start this evaluation….Any music I would play, D90 would always unfold it like candy in front of me. It grew on me because I can now listen to even too-crowded and up-front music with ease, D90 makes that a lot more approachable, I can chew that pill much easier, I’m again impressed.”

“My definition of “giant killer” is this: if the overall performance is close enough in every single category, then for me it makes more sense to purchase the less expensive unit. That's why I call it “giant killer” ...that's why giant killers can be a $300 or $1,000 DAC, it doesn't matter, the price because if a $300

DAC performance is close enough to a $1,000 DAC, that as far as I'm concerned is called a “giant killer.” This TOPPING D90 is a giant killer.”

—Thomas & Stereo

“The jump from TOPPING D50 to D50s seems like a massive one: better SNR, better cross-talk numbers, dual DAC configuration and the best Bluetooth receiver with widest codec support is the cherry on top...This is an amazing achievement for TOPPING, if you really don’t need an internal headphone amp, some additional digital inputs or the balanced XLR output then D50s at $250 is without a doubt an amazing value!”
