Update. APL have a Black Friday sale on the latest release of Virtuoso emulation software - now $79, including simulation of 11 loudspeakers, including ATC, Dutch & Dutch, Genelec and others. It handles 7.1.4 Dolby Atmos from Apple Music, as well as 5.1 surround music tracks from Qobuz, and 7.1 movies from Netflix etc. However, as yet, there is no upmixer, so stereo sound will still be stereo, with the added acoustic of one of the standard listening rooms plus the selected speaker EQ (see below).
The updated Virtuoso User Manual now lists the 11 near-field monitor loudspeakers available for emulation as well as the different room options. Amazing value for $79 - this is now my preferred surround headphone processor when I haven’t got access to my Smyth A16. Although it doesn’t approach the fidelity of the A16 with good open headphones like the Sennheiser HD800, it does have much more flexibility, a far better GUI and manual, and even provides a convincing surround speaker emulation on my Shure 1200 electrostatic earbuds (better than the A16). Quote from the User Manual below.
“SPK EQs emulate the complex and unique frequency response of the loudspeakers. Therefore, they allow you to choose virtual loudspeakers with different spectral balances for your monitoring purposes but also can be used for adding a unique tonal colour to your native binaural mix. More headphones and loudspeaker EQs will be added in future updates.

Note: The frequency response of a loudspeaker depends on the frequency and measurement posi- tion and most near-field loudspeakers have limited low-end response. The SPK EQs are designed to emulate only the on-axis response above around 250Hz, thus maintaining the original low-end extension of the default (None) setting.”
