Default Dual supply B1 Buffer

Hello, I have a question for you. I want to substitute with a B1 Buffer the OP line preamp stage of my integrated amplifier (a MArantz PM78), inside of which there is two rails of supply, a dual regulated +-15volts and a single non-regulated +24volts. So, the question is:

- is it better to use the classic version of B1 using supplied with the single non-regulated rail of +24V? or..
- is it better to use the dual supply symmetric version of B1 (DCB1, without the coupling caps, about which I've just readed some articles) with the dual rail of +-15V?

I would prefer the second option (considering also that the input stage of my integrated amplifier power section is however provided of one coupling cap so I wouldn't have any offset problems) but in this case I'd have two more questions:

- may a total of 30V of supplying damage Jfets;
- can I use smaller filtering caps than 2x15.000 uF, since I use regulated voltage and is difficult to find enough space inside the amplifier?

Thank you very much, great project Mr Pass and great forum!
