I recently bought a pair of SHL5's. My Hybrid MartinLogan's moved to the kitchen/dining area. Initially, I was disappointed by a less defined bass representation (especially when playing dub, such as King Tubby) and also by less of a presence of mid range and vocals (with the Martin Logan's it felt Alicia Keys was in the room with me, or that Wes Montgomery was sitting next to me).
However, what I realized, I am listening more and longer than ever before, and somehow, magically, they seemed to open up last night. Adele's 21, several Frank Zappa recordings, Ernest Ranglin, Keith Jarrett, Sonic Youth, Pixies, The Fall, Sarah Vaughan and Radiohead all sounded great. The presentation is less open and revealing than the Martin Logan's, but I love listening to the SHL5's.
I have no idea whether my ears are getting used to the new set up after a week, or whether it has to do with the mythical burn-in of the speakers and cables?
My system is Technics 1210 with Ortofon 2m black, Musical Fidelity VLS phono stage, Wadia Ipod transport, Cambridge Audio Dacmagic, Quad 24 pre-amp, Croft Twinstar 4 and Harbeth SHL5's. And Skogrand speaker cables (they look cool, cost a fortune, and hopefully add to the whole set up)
