I have just bought a Liteon 167T to replace my old Pioneer 106 (Slot-in) which was really experiencing problems... (high device and disc temperatures and strange noises).
The new Liteon is very quiet and keeps discs very cool. But talking about error correction, I must say I got a bit dissapointed because comparing it with my LTR 52327S, the 167T performs really bad.
Using a very scratched and stained CD-r (CD audio backup), I played it in both drives and with the LTR 52327S it sounded almost perfectly (no clicks) but when playing it in the 167T it was full of noises (clicks and similar).
Also I ran CDspeed and the scandisc feature to scan cd surface and the burner took about a minute to complete it (with many yellow areas, none red). The 167T was VEEEERY slow when reading the yellow areas and tokk about 5 minutes to complete the test. It also showed more yelow percentage that de LTR 52327S.
With CD-DAE, the burner extracts tracks with very few yellow errors (with the verify function) and the 167T shows tons of errors.
Conclusion: I was looking forward to backup my whole original Audio CDs collection because some are getting really old and scratched and I was looking for a good (or the best) DVD reader to make the images to burn, and I see that my old burner performs really better than my new SOHD-167T.
I woldn't like to use the burner for reading and burning all my CDs but... by the moment that's the best sollution I see.
