Highest Paying Banks (Non EB/BB/MM)

In a recent thread someone posted what is written below. Given places like Gordon Dyal, I was wondering if someone could give any insight as to other specialized boutiques with comparable compensation?  

I work at a complete no-name highly specialized boutique IB (<10 headcount) and would get laughed out of the room if I were to encourage people with good experience to apply to my firm if they didn't know comp. 

In my mid 20s, gonna clear probably $550k this year as an As1, averaging maybe 30-35 hrs/week of work, if that.
