Well...couldn't we parallel the jfets as well?
There are a lot of wars about which opamp is the best or better which opamp is closer sounding to jfets (which are somehow the reference sound-wise) and that is why I wanted to use them instead of opamps. But on the other hand is true that with opamps there are a lot of possibilities.....decisions, decisions.
Any words of wisdom regarding which opamp might be more suitable, or sticking with TL072/TL074 which as standard as it gets? I know that sound is very subjective thing so I don't want to start any wars!!!

question
are you limited to running it on battery supply ?
searching on simple diamond buffer I found this

as for the sound
Im not sure you want much influence from a buffer, other than low output impedance
ofcourse you dont want it to kill the sound either

If you were to try opamps then the TL071 series is a good starting point. Sonically they are excellent. Others to try, the OPA2604 and the OPA2134.
Paralleling small signal FET's seems a bit messy tbh. If you were to use FETs then I would stick with the original circuit topology.

@tinitus:No, i'm not limited to run it on batteries, i can use any psu i want and i will probably end up using a low dropout voltage regulator which will do the job. Unfortunately i don't have the scope to actually see the signal or ripple..
Interesting link regarding diamond buffer. I see it is a universal purpose buffer. I don't know about the sound though...is it coloring it? Probably yes, but i guess it's worth a try..
@Mooly: I found out a lot of commercial active crossovers (even supposedly good quality) the TL072 (or TL family anyway) and NE5532 so I guess even if old they're still good/excellent and cheap.
