I don’t have the Pulsars but I do own a pair of Tyler Taylo Reference speakers that use the same Seas drivers (albeit a larger woofer) as the Pulsars.
For me the choice would be easy, I’d go with the Pulsars. They have a tweeter that retails for nearly twice the price of the Seas unit in the Harbeths. The improvement of the costlier tweeter is definitely audible to my ears.
The 30.2s paired with Hegel will give you a very warm and easygoing listening experience, but you’ll also be leaving a lot of detail and resolution on the table vs speakers like the Pulsars, especially if the latter are paired with more neutral electronics.
