For the I/v converter section many say that you need a faster opamp and I see many people use opa627 but people who tried ad815 even said its better than 627 so im thinking to use AD815 as I/V converter being with slew of 900V/usec.
any suggestions or inputs one would give? AD815 is cheaper as well.

I'm using AD815 in my Ozone DAC - its great and excellent value. I don't use it to do active I/V, rather I use passive then filter and post-amplify with AD815. Can't beat it for the price I pay here but it does need a very clean supply - 10uF or 22uF 1206 ceramics across the pins. One great advantage of this earlier generation part compared to the later ones is it works down to very low voltages - I run around 5-6V total supply.
I get AD815 here in China at 6 for $1 - I suspect they're recycled from older ADSL cards. A wonderful bargain.

That's funny, I think the 100K price break was $2.50 or so in 1998 dollars.
