Well, as much as I liked the Liquid Spark (enough to have bought one), I preferred the Magni 3 both on simple sonic grounds and on overall technical performance.
And I like the Magni 3+ a good deal more than the Magni 3, so obviously I prefer it to the Liquid Spark also.
If you like the coloration/warmth the Liquid Spark adds (I did, at least with some headphones), then you may well prefer it over the Heresy. Though from an objective perspective, the Heresy is ahead of the Spark (and the Magni 3+ for that matter).
More specific comparisons, including comparing Magni 3+ and Heresy will be something I cover in a review here shortly.
