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.”

“All my usual bass tests were passed with flying colors. Sub-bass is deep-reaching, has a good sustain and it is always clean sounding. The grainy & blurry bass notes are never present, even on badly mastered music and of course, multiple layers of bass can be spotted on the right music. Mid-bass is not overdone like how others are doing nowadays.

The midrange is on the same level, never enters or leaves the spotlight, always in the middle of the mix. Voices carry emotions and are never dry sounding, nor too wet and warm. I think in terms of midrange performance it is like disappearing without adding a hint of color. If you are looking for a warmer and charismatic sounding DAC, this one will not be for you.

Treble is exceptional, always clean, sparkly up top without making me lower the volume. It bites at times, has a really good texture and I can feel the cymbals hitting my eardrums. It is extremely transparent and very detailed to a point that I started questioning myself If I needed to spend 5 times more for a slight improvement.”

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.”

—Sandu Vitalie, Soundnews.net

“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

“TOPPING DX7 Pro seen a long development time and optimization process, it is already at its third iteration, I know and I feel while listening to it all the care it went through in terms of design, specs, and measurements. I can’t deny the awesome specs and measurements it possesses.

It delivers a solid performance on all fronts; it has everything a knowledgeable audiophile would desire and as result, I consider it an incredible all-in-one device packed with features that came as a bonus for a close to perfect audio performance.”
