Help with finding ultra-transparent pre-amp


I got a new player, Wadia 581i SE, and once I hooked it up directly to amps I realized that my pre-amp is not transparent enough.
To make a long story short, I would like to find a very transparent pre-amp to be inserted between player and amps (no coloration, no shift in tonality, and no loss in dynamics, micro or macro), that would result in a sound indistinguishable from the sound of my player going directly to amps.
Essentially I want a wire with attenuation control. Balanced connectivity is preferred.
I tried a transformers based passive pre-amp (it was a custom, very well executed job), result was not good, not only that it killed dynamics and resulted in a dull and uninteresting sound, but transparency was in fact worse in comparison with my present pre-amp.
Is there such a transparent pre-amp, or it is just a pipe dream?
The cost is of course to be considered, I would not go for anything that is more than let’s say 3.5K, new or used.
I have been reading about Placette (resistor based), has anyone had any experience using it in a system that has very resolving front end?
The rest of my system:
Bryston BP26 pre-amp
Bryston 7B SST amps
PMC IB2 speakers

Tvad, sorry you took this personal, I am only telling Sashav that the Lamm LL2 Deluxe can be a good choice and not to rule it out because of one negative thread. If you don't like what I have said, then take a hike and leave your thoughts out of this forum.
Sashav, good luck on finding the right preamp. I have had many high end preamps and I have found this LL2 deluxe to be just as good as most very high end preamp as a stock preamp and at a very reasonable price. With the modifications that I have done on this LL2 Deluxe, it will be very hard to find any stock preamp to out perform this preamp.

Well, took delivery and set it up about 10 minutes ago. Cold out of the box it's obvious this is something.
beware of what you want, for you may get it, tehn what ?

most preamps tend towards the "truth". pick any solid state preamp, and most tube preamps. you won't be disappointed.
you will attain as much resolution as you want and more.

here is a simple suggestion: nuforce preamp.
Bar81, no more suspense please, let’s hear impressions, from the cold start :)
BTW, what is the rest of your system?
