Wagon Master (1950)

The Warner Archive blu-ray is an improvement over the the Warner DVD since its bass frequencies are more intact. Its high end is slightly less detailed, but only just. 

The IVC blu-ray sounds the best to me, and it's an anomaly as far as IVC releases go -- most are sourced from high-generation dupes, but this one is as detailed as the official Warner blu-ray, if not more so (listen to the end music, which is actually less distorted on the IVC).

And just to show how misleading a clipped waveform can be, after stretching the IVC track by a factor of 1.00051 (which brings it in nearly perfect sync with the Warner blu-ray), it looks like this:

The IVC blu-ray, using a Lobster Films transfer from whatever dupe elements were available to them overseas, looks poor but sounds great. There's some massive clipping present (probably courtesy of IVC), but everything sounds more natural than the Warner Archive DVD, which itself was already better sounding than most Warner DVDs. The main issue with the sound on the Warner DVD is its bass, which has been cut severely. The IVC blu-ray sounds deep and rich during the song sequences, while the Warner DVD is just missing lots of detail down there and sounds thin.
