So how does the Sondek LP12 sound after the Dewaudio Starmap upgrade, compared to the Sondek LP12 before the upgrade?
A significant overall reduction in noise floor - yes, the stock LP12, by todays' standard, is noisy. Sound stage enlarged in all three dimensions. Significant reduction in artificial mid-to lower bass bloom. Virtually removes upper bass and midrange colouration typical of the stock LP12. Much improved resolution and separation of layers of detail within the sound stage. An improved sense of timing and rhythm. A sense of stability with regards to imaging. All things considered, a significant overall improvement to the classic LP12!
