Naim CD5 XS player vs 5si player

I'm interested in the Sparkler model S515 "ballade" Integrated CD Player just released in April 2021 --- uses a 16-bit non-oversampling DAC, Philips TDA1543   - wonder how this compares with the Naim players which use PCM1704 chips?

I wish we could see a professional review or user review of the Sparkler Audio S515 Ballade  CD player.
