Couldn't find anything in here on it, so thought I'd share.
Yes Im the guy who brought it up on FB in 'that' SQ forum.
In a nutshell:
Helix's new DSP amp combo.. Highlights..
- Something close to DSP Pro processing quality in 8 channels
- 6-channel amp with actual power, unusual for such a piece
- Sub channels RCA out to a sub amp (processed).
- Optical input like their other DSP's
Badassness in one box.

P SIX DSP
The 6-channel amplifier P SIX DSP not only delivers loads of clean power and a top-notch DSP processor, it also comes with a completely new output stage concept that combines the benefits of class D amplifiers with the sound quality of class AB technology. Our unique “Class Ultra D” concept eliminates the negative influence of the indispensable output filters with a revolutionary concept that incorporates an analog feedback path back to the digital domain.
The result: Incredible damping factor (up to 1,000) even at 20 kHz, no load dependency of the frequency response and lowest possible THD for unparalleled sound quality. Almost needless to mention are the numerous input options including SPDIF optical and a HEC (HELIX Extension Card) slot for e.g. Bluetooth® audio streaming or other additional functions.
The P SIX DSP incorporates the same ultimate audio DSP with 64 Bit resolution and unbelievable processing power as HELIX DSP PRO. Two additional RCA outputs allow extending the system with external amplifiers up to eight processed channels. Despite this impressive bundle of engineering know-how the P SIX DSP shows up with a typical, clean design that has remained very compact for easiest integration.
