  • TOPPING A50 & P50 Review = Double Impact!

    What a crazy and crowded year was 2019 for TOPPING. They were able to release not one, not two but three flagship DACs: the technical and serious DX7 Pro, its musical and playful brother D90 and the D70 that sits somewhere in the middle of those two. TOPPING didn’t forget their core fanbase and updated their 50 line and even added new affordable products, D50 was upgraded to D50s that made some nice quality of life changes for old-school loudspeaker enthusiasts, they added a much-needed A50 headphone amplifier and that must-have P50 external linear and regulated power supply that works with both of them.
  • Moondrop Starfield IEM Review

    Nobody believed single driver IEMs could sound as good as top-of-the-line multi-BA IEMs. That is until Sennheiser proved everybody’s wrong with the release of the single driver IE800 in 2012. It sounded so good that the IEM market changed forever, suddenly hybrid earphones made an appearance and other brands started embracing single driver IEMs. Today we will be testing an entry-level model of the Chinese manufacturer Moondrop Technology, that thanks to the unique color pattern on the IEM body and cable were simply named Starfield for obvious reasons.
  • TOPPING D50s Review: Potent Essence in Small Bottles

    This year was such a busy year for TOPPING and I’m sure it was their best one yet. TOPPING released two incredible DACs that can fight in the heavyweight category with bigger boys, D70 and DX7 Pro were such eye-openers that they made me wonder if much higher priced digital to analog converters made any sense. They are still tuning their top-of-the-line AK4499 based D90 DAC, but in the meantime, an update to their smaller and more affordable DAC category just happened with the release of the newest D50s DAC/Preamp and Bluetooth receiver. I’m told there is also an A50 headphone amplifier in the works that should pair nicely with D50s and the dedicated P50 power supply should solve any background noise issues you might have.
  • TOPPING D90 Review – A Genre Master!

    I knew TOPPING was brewing something new about one year ago, something that would sit on an iron throne in their product line, in the summer of 2019 I found out it’s their flagship D90 DAC that just entered its final polishing stage. Taking into consideration that TOPPING is playing with the reference AK4499 boards from AKM for about 2 years now, it’s clear to me that they didn’t rush this one as others might think. Yes, it is among the first available commercial DAC equipped with the newest and greatest DAC chip from AKM, but behind all that, D90 had a long research and development time and it’s finally ready to sing beautiful songs to the world.
  • TOPPING DX7 Pro Review - A flagship for Everyone!

    TOPPING DX7 Pro 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. At just $100 more compared to the older DX7s I believe DX7 Pro fully justified its price and at $599 this is currently my best recommendation.
