    If you were sticking with single ended I'd say a schiit saga would do the trick. Freya maybe? I think pass labs makes transparent preamps too but they are pretty expensive. I realy want to purchase one of those TVC thingies but I can't I just spent so much on new speakers... it would be great to compare 3-4 preamps.

    Try a Freya. If you don't like it, you can send it back, but I'll bet you won't.

    I've played around with a few different options, and overall I liked the TVC the most. However, mine is collecting dust at the moment because of the convenience of digital/onboard volume control (and one less component on my cramped desk).

    Goldpoint sells basic passive resister-based preamps in balanced and single-ended configurations.

    Channel Islands Audio has some potentiometer-based passive preamps with a few more bells and whistles (like toggle switches or a remote control) but only single-ended, but I think their VRX•1 balanced cable is designed to provide balanced operation with their passive preamps. You'd probably have to ask them how to use it.

    if you want absolute certainty about which is the best category of anything I would suggest to join a religion.

    I do not think there are absolute truths in audio. We are all trying to solve the same differential equation, a long time ago I learned that the solution of such an equation depends on the boundary conditions. So depending on the individual conditions there will be different optimum solutions.
    So far I have gathered that you have an Ares sitting around but you lack a preamp, are you listening with speakers or with headphones?
    @Torq said that listening with headphones he found SE output superiour to balanced output, this may be an indication that you do not need a balanced preamp if you have no other source.
    Using to the Ares with speakers I could not make out a sonic difference between the different outputs.
    The Ares is quite hot it will output 2.3 V SE and 4.5 V balanced if I remember well. The one or other might be better for your transducers.
    If you decide for a TVC as a preamp the whole point is mute because the TVC will transform SE to balanced if you use the preamps balanced output. In that case using the Ares’ SE output you would get max. 2.3 V balanced out of your preamp.
    With a TVC the more you attenuate the lower the output impedance will get, given the Ares’ quite high output impedance that might be interesting, because then 4.5 V will give you the possibility of more attenuation. Again whether you need that depends on the input impedance of your transducers. As someone pointed out the inductance of the transformer also plays a role.

    Now I have just scratched the surface of all things that might matter.
    No one will be able to present you a ready made solution on a platter and if someone did I would not trust them.

    Experiencing music is something joyous and passionate at least for me. So delving too much in theory instead of listening is probably not the best way to do it.

    If you have the feeling that TVC is a valid preamp option and the Promitheus is within your budget why not go for it?
