Hi @ja_kub_sz thanks for your post. I'm glad you're enjoying your Cen Grand. Can't believe mu OP was over a year ago; boy how the time flies
Anyway, thanks for your post; your observations certainly match my own. I did however have issues with my first Cen Grand unit, the Standard edition, and eventually had to call the distributor again. I was going to give up on Cen Grand at this point (left channel kept dropping out, after changing ICs, I couldn't get any sound out of it at all). The distributors customer service was top notch.
I asked him to order me a Pontus II and I would return the Cen Grand, but he offered me the next up in the Cen Grand DAC line; the Super Clock edition which comes in at £3200, for no further cost of what the Standard version cost £2500 iirc.
This was last Spring and still going strong, no problems whatsoever, and the Super Clock just raises the bar over the Standard, more of everything.
I've also had a speaker upgrade since the Cen Grand; swapped out my Triangle Comete 40th Anniversary for a pair of ATC SCM 40's, and also brought in a Marantz Model 30 in place of my Atoll IN200.
At the moment, not looking to change anything; very happy.
Merry Christmas everyone, hope you and your familes all have a great festive period, and a Very Happy New Year 🥳🎄🥳🎄🥳🍻🍾👍
