Interesting question deserving of a response. Firstly, I guess it depends on your personal circumstances (age, mortgage, family etc) as such a move is risky. Secondly, how good is your relationship with current/ previous clients - would they come to YOU rather than current company for new work. What is niche consultancy offering? I would suggest such a move is not "salary based" but based on lifestyle, challenge and share options etc. as you will be required to do a lot more at a niche company. I made such a move about 6 years ago (now run my own small independent consultancy) for very much your reasons and haven't regretted it .... apart from regular bonus! I'm afraid only you can "join up the dots" as to whether this is good for you.
