TVC Promethius versus Bent

Any impressions on differences from this that have tried TVCs from both these companies? Also, I'm not sure why a transformer would help over of a passive resistor based attenuator (assuming a very high quality pot)assuming drive, low output impedance source, low capacitance cables, high sensitivity amp with high input impedance (100kohm). If more is less, why isn't adding a transformer just more, though minimal, distortion? Sort of two questions, but I have a high quality passive volume control, but have an interest in the TVC idea, especially these two brands or something made by Kevin Carter.

I have the Bent Audio TVC and find that the transparency that this offers is remarkable. It is feeding an Atmasphere S30 Mkiii OTL which works fine as a combination for me as my speakers are very effiecient (Duo's 108 dB/w). I have tried various active pre's including the Atmaspere MP1 and in my view the TVC wins hands-down.

I can recommend the Bent Audio without hesitation (if you can find one now) - they are really well made.

I have to confess that I've not tried the Promitheus but I reckon it would offer very similar performance. Good luck.
