Disclaimer: The Apos Ray 12AU7 tubes were temporary provided as part of a European loaner tour The new production Apos Ray 12AU7 tubes come in a very nice compact box with magnetic closure. I connected them to the xDuoo TA-22 hybrid tube amplifier as soon as I received them (they had already been burned in by a previous reviewer). After a bit of a warm-up on first listen, it was immediately clear that the sound of the Apos Ray 12AU7 tubes had gained in clarity and refinement compared to the xDuoo's stock tubes. Really a good upgrade for the xDuoo...

Disclaimer: The N7 was temporary provided as part of the European loaner tour Right after the unboxing and the first boot-up (that happens very fast in comparison to many other Android-based players) you are presented with a clean and minimalist environment: no bloatware installed, just the Cayin player and HibyCast apps (and some other utility apps, not even the "stock" Google apps besides the Playstore) with an really up-to-date Android 12 version that will enable to use the device for quite some time on top of the system drawer you have easy...

Impressions After the many listing hours my first impression of a very open and invitingly big sounding 3d space with punchy bass remained as of one of the key properties of this headphone. The look might not appeal to everyone with the colourful orange dyed wooden cups that really stand-out in contrast to the silver finish and the brown ear-pads. Its a very substantial build and comfortable to wear even for many hours with virtually no clamp force. You get a transportable case coming with the Audivina, but the headphone itself is not at really...

very balanced sound signature with tastefully boosted bass, that never overshadows other frequencies vocals are clear and not recessed great build quality and feel good detail and not always forgiving with badly mastered tracks very good fit and sleek look stock tips do fit for me well, but might be possible thar 3rd party tips could improve seal on certain jaw/skull movements ... if the seal is broken, bass gets impacted/reduced (depends of tips and ear) above average passive isolation also very good at lower listening volume included cable is not...

Right after unboxing I plugged in the Liric into the Singxer SA-1 that was fed by the Denafrips Ares II and started listening. I wasn't immediately wowed like the first time I was listening to the Empyrean. But some headphones just need some time to grow on you. The sleek look and substantial feel of the Liric is just impressive, I doesn't have the majestic grandeur of the Empyrean, but lets you know and feel that you have a well engineered and durable headphone in your hand with a penchant for understatement. Also very comfortable to wear for long...

I possess the little brother Questyle CMA 400i for many years now and still a big advocate of this all-in-one unit, so I was eager to see what the current top-linne model can offer. I was always close to buying the Questyle CMA Twelve Master but was so pleased with the CMA 400i that it didn't happen. As part of the European review tour I received the marvelous Questyle CMA Fifteen to try out for myself. So I brought ALL my current headphones to the table to be tested with the Questyle CMA Fifteen over many days ... Headphones that are very good...
