Default National Semiconductor LM4562 used as a line preamp.

I would like to hear opinion/experience from anyone who have actually used this new op-amp from National.
I intend to try it in a line preamp in the next future.
Thank you very much.
Kind regards,

beppe

Thank you very much Mr Andy.
My fault.
I have been overexcited by some extremely positive words about it. Hope it will sound nice also as a simple unity gain buffer.

Thank you very much again.
Kind regards,

beppe

Thank you Mr Andy.
Given the really high reputation of the OPA627 I think that I will try it as a unity-gain buffer for start.
My power amp needs 0,5V for max power and has a 5kohm input impedance.
If only I could find a ready to use pcb to purchase ...
I see that a DIP version is available (no SMD abilities here).

Thanks and regards,
beppe
