The X-1 is one of the best sounding SS preamp that I have heard. I compared it to many tube, SS and passive preamps. That being said, the mid range is not as sweet as a good tube preamp. The X-1 bettered most tube preamps in the dynamics and low end department. So it comes down to a matter of preference. The new Sonic Euphoria passive preamp is a real sweet preamp for the price. My amp is set to low for a match but it was a really good performer for the price. The Placette active will beat the SE but for much more money.
Happy Listening.
