I agree with the Tom Evans Vibe and Pulse preamp. Not warm like tubes (I am taking CJ warm) but it did offer a 3D soundstage that no other SS preamp I tried could reproduce. Music floated back to front out of a black background. I did not have the additional power supply but I did use the preamp with a Pass Labs X-250 power amp. At the time I auditioned one, they were still very expensive and it was out of my price range then. If you can pick one up used for cheap, buy it.
Happy Listening.
