i'm not sure you will see an improvement with additional run-in but here's a tip (certainly not original): place your speakers face-to-face as closely as you can and run them out of phase (reverse cables at amp or speaker posts on 1 channel v. 2nd). this will allow you to play the speakers at relatively high levels with much less audible sound being produced. i recently broke in a pair of avalon eidolons, which also require 300-700 hrs. of play. i used the technique noted and also covered the speakers with thick, light quilts to further muffle them. they played continuosly for >400 hrs. with barry white: icon of love on cd repeat. this is a god-awful cd but has the best continuous low-level output of any disc i know (it's been used by my dealer/friend, who owns it, on several pairs of difficult-break-in transducers.) i don't envy the listening restrictions in your flat. my sound room is on the 1st floor (basement in us) while our bedrooms are on the 3rd; even with these distances, i had to turn down the volume on many a night during this tedious process!
Running in speakers?
After aborted attempts at securing a Bel Canto Dac1 purchase (see posts on Hellohifi debacle)to the UK. I decided to spend the money I didn't have on new(ex-dem) speakers-a lovely pair of Proac Studio 150's. After intially being blown away by a more 3d soundstage and plenty more detail I am now starting to note perhaps some of the harshness et the high end associated with these speakers before they run in-it's also acknowledged they take a long time to run in. Any tips on this? I live in a flat so extended periods (ie overnight)with the volume up isn't practicle. Does the volume level matter? Thanks in advance. Ben
