The Sierras have kept me up way after my bedtime these past few days!

After another 15 hours or so of critical listening, I'm impressed by the superb soundstage of the Sierra-1s. They're not only accurate in width, but also in depth. They render the room that the performance was captured in, something I'm not quite used to hearing! The relaxed nature of the Sierras means I can listen for hours on end. My preferred sound is one that's a slightly bright and the pairing of the Sierras with a Panasonic XR57 is wonderful to my ears.

Another reason for the late nights is that I've been A/B-ing a pair of Onix Reference 1s in comparison to the Sierras. I can post more detailed thoughts and comparisons if folks are interested, but in summary, I do prefer the Sierras.
