I am sharing this experience for those who are considering building the EROS.
I'll start by saying that in the system I'll be using it, the EROS is the single cheapest component. The turntable (Rega RP6), the Amp combo (Naim 72/hi-cap/140), the streamer/DAC (Auralic Aries / Vega) and the speakers (Larsen 6.2) all cost at least 2X-5x at minimum it's price.
I have been using the on-board Naim 72 phono board in the pre-amp, and I've been annoyed by the fact my streamer/DAC streaming Tidal sounds better than my records - as that demotivates me from playing records - despite the fact I prefer the ritual of record playing.
Enter EROS. After, well, 15 minutes of warm up and no prior burn-in, using cables half the price my streamer combo (for now) I can confidently say, records sound better than the digital chain.
EROS brought a new level of transparency, delicacy, depth and expansiveness to the sound with all my records. From Nils Frahm and Talk Talk, to '50s blues records or HipHop. It also brought a focus to all the voices on records with both female and male voices that previously was missing.
Records + Eros + Rega RP6 with $50 interconnects beat Auralic Vega + Auralic Aries + $300 cables.

Thank you Bottlehead team and the community who commented and helped me build it.
Can't wait to build more glowing tube things from Bottlehead.
