Thanks to Jean-Philippe C. for his feedback:
It is with pleasure that I share with you the purchase of my octavio amp 32V. They are associated with speakers that have been forgotten today (the famous Philips from 1975 ref: 22rh53, well known to audiophiles. I also associated it with a small focal evo subwoofer. The sound is just precise in the midrange, and the tweeter is very crystalline. (non-fatiguing listening at moderate volume on octavio). This octavio is really very promising. Very refined design, I love it. Thank you cordially. (I am impatiently waiting for the adjustment on the bass application. Thanks again.
