Modwright KWA 150

Hi all i have taken the plunge and ordered the KWA150 and the LS100. The LS

Can any tube owners advise how long the LS100 will take to break in and what sort of sonic changes there will be once it has broken in compared to say at 20 hours use.

Both of these units will take 80-100 hours to get 75% broken in. Anticipate 400+ hours on both the KWA-150 & L'S-100 to get 95% break in.

Anyone have a modwright kwa 150 wilson w/p 8 experience?
