Both models are based on the same technical foundation. Therefore, by replacing the standard oscillator with the hand selected SE120 oscillator, we can turn your REF10 into a REF10 SE120! Of course, this is followed by a full test of your unit and the final calibration of the new SE120 oscillator. In addition, you will receive an exclusive phase noise measurement report of the oscillator used in your unit, which includes its serial number and that of your unit. This gives you the guarantee that your oscillator complies with the specifications we have prospected.
The upgrade has a clearly noticeable positive effect on the sound quality of your connected audio devices: aspects such as resolution, spatiality, coherence and realism gain considerably. The acoustic stage becomes even wider and the sonic depth of the instruments even more concise.
Some testimonials from delighted users:
My initial expectations from the upgrade were modest: perhaps to detect a marginal difference at best. Oh boy, was I wrong. The SE120 has pushed my system to new heights.
Guy Zilberman, Thailand
I listened to my upgraded REF10 and the result is amazing: the separation between instruments, harmonic richness and spatialization are much better than before.
Frédéric Laglaive, France
I didn't thought that the difference to my ‘old’ REF10 would be so huge. A real blast!
Daniel Steinert, Habst Kabel, Germany
I am really surprised, I would not have imagined such a big difference with the REF10 SE120!
