has actively introduced its high-end audio technologies into the wMini HPA.

This combination is renowned for its sonic perfection, as it is used in reference brand headphone amplifiers from many famous brands. The headphone amplifier is a combination of guaranteed performance from the ES9018K2M, a popular DAC chip with excellent performance, the OP275 with a neutral I / V conversion chip, and the TPA6120, a headphone chip with stunning performance. This provides incredible amounts of headroom and agility in delivering your music as well as it can. The WAP algorithm in their flagship DAC uses more than 10x the processing power of an Intel Core i7 and some of this power has been implemented into the wMini HPA which uses WAP Level 2.įor the headphone amplifier Waversa decided to use two of Texas Instruments TPA6120A2 reference amplifiers which utilises direct-current topology to ensure enough current is delivered to demanding headphones. This, unlike other implementations means that Waversa has complete control over the data stream and uses advanced async transfer and low speed clock on the input which reduces jitter. This algorithm uses it’s own high precision master clock to directly talk between the ESS Sabre ES9018 and input interface such as the USB controller.

Internally is has been packed full of technology including Waversa System’s proprietary WAP or Waversa Audio Protocol which is a range of algorithms that make their best effort to recreate and lost information, unlike upsampling that can actually create digital artifacts and noise. It is DLNA and Airplay compliant meaning that you can use compatible applications on your phone to stream to it and has standard connections such as USB, Coax, Optical and Ethernet. Being ROON Ready it simply acts as an endpoint using ROON’s own RAAT protocol, meaning that you can control it using your smart device with incredible ease. The wMini HPA is the perfect companion for your music streaming requirements with a range of different inputs that are available. I was exceptionally pleased that the wMini HPA has a minimal amount of audible hiss with the Andromeda that can only be heard if you really listen carefully. The other problem that I was struggling to overcome was the hiss that can be heard from high powered headphone amplifiers when using ultra sensitive earphones such as the Campfire Audio Andromeda. With it’s balanced and unbalanced output for both headphones and earphones it provides incredible versatility for users with a plethora of different cables and connections. The wMini HPA has an ultra high quality streamer and DAC integrated behind a very capable headphone stage capable of effortlessly powering some of the most demanding headphones available. Solving the issue of having multiple boxes all doing different things. The truly amazing wMini HPA MK2 provides the user with the ability of having just the one device sitting on their desk or next to their bed to fully enjoy their music from a massive variety of sources. It took me an exceptionally long time to find a product of this quality that was fully ROON compliant and that provides an amazing sonic performance for any music that is played through it. The Waversa wMini HPA MK2 is a multi purpose ROON enabled headphone amplifier capable of driving some of the most demanding headphones such as the HD800 and Abyss 1266.

There is no entry for the user manual yet.ROON Ready Waversa wMini HPA MK2 Streaming Headphone Amplifier The existing crossfeed is renamed to “Custom” as it allows itself to be customised. In the user interface, the new crossfeed option appears as “Meier” and is not configureable. one instrument only on the left, another only on the right).

The crossfeed effect is quite subtle and is noticeable mostly one albums that have very strong left-right separation (e.g. This implementation is quite lightweight, just 3 multiplies per left-right pair of samples, but only has a C implementation right now (no asm). A difference with the crossfeed already present in rockbox, is that this algorithm keeps the total spectrum flat (the one currently in rockbox accentuates low-frequency signals, making it sound a bit muffled). This crossfeed blends a bit of low-pass filtered L signal into the R signal (and vice versa) while adding about 300 us delay to the crossfed-signal.

Crossfeed dsp algorithm Patch#
Attached patch adds a new crossfeed algorithm to rockbox, emulating the basic “Meier” crossfeed (2 capacitors, 3 resistors) as discussed in
