After having had installed Audiophonics IAN CANADA FIFOPI ULTIMATE reclocker in my Audiophonics DAP/DAC Sabre ES9018 Mk2 100Mhz by sound engineer www.lentusaudio.nl, they advised me to order the 45Mhz and 49Mhz Ultra Low Jitter clocks to replace the standard ones.
The results are extremely good! More rifined highs and lows. Blacks are black (silence is silence).
Listening has become much more relaxed with every kind of music.
