To enjoythemusic.com φιλοξενεί δοκιμή του παθητικού προενισχυτή της Promitheus Audio (με έδρα τη μακρινή Μαλαισία) που έχει προκαλέσει πολύ θόρυβο στο AudioCircle forum. Η τιμή του εξαιρετικά χαμηλή και τα σχόλια του reviewer διθυραμβικά.
"Because the TVC SE is passive, there is no power supply and therefore no power cord. It works differently from a conventional "passive preamplifier" which is usually nothing more than a volume potentiometer, source selector switch, input/output jacks and the related wiring to make everything work. Using a passive preamplifier, the output of the source component drives the input of the amplifier directly. This isn't really the best way to get the job done: it is the audio equivalent of attempting to mow an acre of grass with a sickle as opposed to a tractor. Adding transformers to the recipe changes things entirely: they act as a buffer between the source and the amplifier, and makes it easier on the source component to drive the amplifier. Interestingly, the lower the volume setting of the TVC, the easier it is for the source component to drive the amplifier. This is the opposite of the way things work with a conventional passive preamplifier.

Conclusion
Do not let the low price of admission or the handmade appearance fool you. The Promitheus Audio TVC SE is not a curiosity or a toy. It is a serious audio component, and probably the very best bargain in audio today. It doesn't have the visual or tactile panache of its more expensive counterparts, but sonically, it runs easily alongside the "big dogs." The nature of its design results in total and complete transparency. Because of this, the quality and compatibility of the rest of the system components is critical. Vinyl lovers will need to pay special attention to both the output of their cartridge as well as the gain of their phono stage. However, at the end of the day, I find the Prometheus Audio TVC SE to not only be a joy to "listen" to, but also an invaluable reviewing tool. I will be keeping it, and I suspect it will be hooked up most of the time. This component gets my very highest recommendation."
