These days a large portion of the new audio speed op amp series from TI, AD, NS, and B-B are pure CMOS. LT, for some reason has not moved in this direction as completely as the others have. TI, in particular has a large range of low noise CMOS op amps avaiable. BTW, The OPA 604 part is from BB, and is not all fet, but the direct signal path is "all" fet. Barrie Gilbert (of AD) wrote an interesting article in EDN recently about the future of Bipolar where he discusses some of the reasons for the current trend to CMOS for op-amps
