I use this exact combination of products and could not be happier. I agree with markxiii that the LA150 is drier than the LA100 but with more air and more extension. I find the LA150 suits me better, although I never heard the LA100 with the berning amp and VSM-M. At the time I had the LA100 which I used it with a VZN-80 and the VSM-M speakers.
LA 100 MkIII is my absolute reference line stage: dynamic, smooth, detailed and with wonderful midrange liquidity and richness. I heard the LA 150 and thought it was very similar in overall character, perhaps a little drier and with a touch more "air". I'm sure you would be very happy with any of them.
