I have k3b already, it looks good. However, it disclaims any support at all for ATAPI writing, and while my version of cdrdao *should* be fine, if I can't get it to write using cdrdao I don't see that a gui frontend will help. Also, at the point I was trying this, I had two large .wav files with a .toc splitting them up on offsets (generated by gwc) - k3b doesn't grok this (cdrdao does). It turns out neither does nero, so I split the tracks up anyway using gramofile and then burnt to cd using nero. I'll try k3b next time, for writing separated tracks to cd.
It seems a lot of the tools are still playing catchup with the cdwriting interface in 2.6. IDE-SCSI is either deprecated or just plain doesn't work, I've not yet established which. cdrecord has support for ATAPI, and it seems to work now from the command line, but its not so good from xcdroast. k3b claims to only understand the IDE-SCSI interface. Not tried eroaster or gcombust yet.

+Having written this attempt to CD, it seems pretty good. I don't have the turntable hooked up to the stereo to compare the quality, but there are no pops, very little crackle. There is some residual noise still, and the gain is still too low, which makes the noise somewhat worse. When I amplified it before processing, it was amplified to the highest gain possible without clipping - however that was based (I think) on the highest amplitude seen, which was any number of the pops that occured there were about 10 - 15 times louder than the rest of the track. I'm not sure if this will improve the effect of the noise reduction algorithms, or if it will screw things up totally, but its probably worth a shot.

+Selecting a better noise sample may also help, although I suspect its about as good as I can get. I'll move onto the next vinyl for now, which I know is in worse condition in some ways (at least one scratch bad enough to cause the needle to get stuck), but may have better properties overall. And the other thing to do is to try an external amplifer/equaliser unit, although I only have the stereo the turntable is connected to, which isn't overly great. I'm open to offers :)
