A few of my favourites:

Frank Muller: I've listened to stuff throughout his career; he could do quiet and grave, and he could do spine-chilling too. Ran the table, really. Was a shame what happened to him.
George Guidell: Dry, but actually really effective, and you can tell this guy is/was stage-trained. Doesn't fit for everything but what he does, he does really, really well.
Pete Bradbury: He's not the most amazing in any category, but I just really like the way this guy reads stuff. Only issue is, he's a bit nasal, as if he's getting over a cold all the time.
Robin Miles: I could listen to her talk all day. Warm, gentle voice that has tons of expression in it. Doesn't overdo anything, and has a sense of what she's saying and how it comes across.
David Aaron Baker: Again, he's not amazing, but for the Odd Thomas series, he just...works. He can be perky and then grave, funny and then sad. His accents are nothing to write home about, but I have trouble picturing anyone else as Odd.
James Marsters: Same deal, except with Harry Dresden. His first few books, you can tell he's still learning his craft (a lot of volume/pacing/tonal issues) but as he gets further in, he gets much, much better. I love his sense of the ironic, as well as his ability to do tons of different accents (admittedly with varying degrees of accuracy).
Nick Podehl: This guy has read several books I like, and apart from the fact that he's woken me out of a dead sleep several times by yelling, he's excellent. A generally higher male voice (I speak in the approximate range he does, actually), his voice does all kinds of emotion well. He's one of those voice actors who doesn't try super-hard to have a million voices, one for each character.
Steven Fry: I've listened to Harry Potter as read by Jim Dayle, and it's not bad. Fry is more subdued in some places, but overall, I'm sorry to say this, he's just...better. Older-sounding, certainly, and less exciting in some places, but he's far, far more consistent, and personally he's the voice of the HP series for me, even though I'm Canadian, not British, and read the first three books as narrated by Dayle before finding Fry.

James Masters. Aka. Spike. Reading the Dresden Files....yes please.

I also Like Alexander J. Scorby. He was actually one of the first audiobook narrators, back in the 1950s.

definitely agree on Williamson's version of the Hobbit, but it's a pity it was abridged. Wish he would've actually read LOTR as well.
In contrast to Jade, Jim Dale is the voice of HP for me. I've read Fri's versions as wel and Jim Dale just... brings so much life to the characters. Just goes to show that two people can have wildly different opinions, both equally valid, about the same thing. I swear by Jim Dale for HP and likely will never change my mind on that one. lol
Mark Thompson, reads ome of the star wars legends novels, and does a fantastic job... I haven't actually looked into see what else he does.
Richard Rowen from graphic audio is my favourite narrator from that company. He has the ability to narrate anything from fantacy to comedy and can match his reading tone to either one, serious or light-hearted. I also don't listen to much in the way of audio books that aren't from Graphic audio. lol

Jonathan Davis is the best star wars narrator, as far as I'm concerned, though mark Thompson is very good. Sad so many of the star wars books are abridged.

I'm just going through my hard drive to spot good narrators. Whoever reads the red queens war series (no idea of the name) is superb, wish he read more; you don't get many bad Stephen king narrators either really. Helen Duff is definitely the better narrator of the book of the ancestor series, Anton lesser also good.

The award for absolute worst narrator goes to Roy Dotrice, he made ASOIAF unlistenable for me. The job should have gone to a more experienced (but not 90 year old) fantasy narrator imho.

No argument made. Just a civilized discussion about differing opinions. I think most of those inconsistencies stem from the fact that there were changes made after the movies released, since he reads the American versions of the books. But everybody has their own taste, of course. There's just something about his style I like, enough so that I can look over some of the small things... the way Hermione greets Harry, for example, never really got to me. His rendition of her confronting Ron in the 7th book when he comes back is nothing short of spectacular even when I compare the two side by side. Same thing in the Goblet of Fire when the Weasleys go get Harry from the Dursleys. Fri's version of both scenes just lack something in both of them, though I can't really put my finger on it.

@11, again, differing opinions. Jonathan davis is good, but MArk Thompson is where it's at. All of davis's voices for some reason end up sounding similar, even if his tone and expression changes. Thompson just seems to do so much better with different voices, and I like his expressiveness as well. And it definitely is a shame that so many of the books are abridged!

Well I don't read audiobooks anymore, but when I did I had a lot of favorites. Len cariou, read Michael Connelly's harry bosch books, his narration is very convincing, the only thing I don't like is that his voice is so low that he can't do children's voices accurately. And frank muller will always be my number one, all the books he did are masterpieces. Then Richard ferrone, dick hill, and john rubinstein.

Jim dale is probably one of my favorite narratoers. The only books I have heard from him are the Harry Potter series. Ive heard the first book by Fry, and Dale is just better for me. I don't like how Fry pauses in places, and he just reads too slow for my liking. However, I do agree with Jade about the fact that Jim Dale does say Haryyyyyyy and I have no idea why he does this. I love his singing of some of the songs in the book though. Fry doesn't do this, at least he didn't in the first book, he just says them. A lot of people are probably going to hate me for this, because I have talked to a lot of people who don't like this narrator, but I really like Eric Sandvold. Not his Harry Potter books narration, those are just better read by a british person, and he doesn't really do them justice, but he does a really good jub with everything else he reads. I don't feel like he gets talked about enough, so i'm bringing him up here.

I like Eric Sandvold too. He is definitely a narrator that adds charm to a fantasy. Some of the pirated library of congress stuff that is floating around was recorded at the wrong speed, and he sounds like a chipmunk, but I still like it. Back when I didn't read ebooks, and only listened to audios, his LOC readings were the only way I could access Tad Williams' Otherland, so I associate his voice with one of my all-time favourites. I'm also in the Jim Dale camp when it comes to Harry Potter. Although in Britain, I think I'm a minority of one. I just heard Jim before Stephen, so for me he was the voice of Harry Potter. I get the criticism about the way he does Hermione, but for me he's another one who just brings a bit of charm to a fanciful tale.

RNIB had a few dodgy narrators back when its talking books were read by volunteers. It's a bit ungrateful perhaps, seeing as how they were giving up their time free to make books available to people like me, but some of them were pretty funny, and some were simply unlistenable. There was one old guy who had a boiled sweet stashed in his cheek. I spent the whole time just waiting for him to adjust it and have a swallow. Another one kept turning her head to look at her cat that was meowing in the background. The worst one I remember was a narrator who left massive pauses between every sentence to the point you just lost the will to live. And the worst thing was, it was the second book in a series, and the first had been read really well. It used to really piss me off that RNIB never seemed to use the same narrator for a series. You'd get things like Lord of the Rings read by three different people. Thankfully they mostly have permission to use the commercial audios now, or they pay proper voice actors.

Bob Askey, and David Palmer, have a similar flat delivery that works for consistencys sake. Yes, it's not great for character voices, but if you just want the material you kind of forget about the voice because it's so consistent. Sanvold isn't bad, but don't listen to him do harry potter.
