The Sony UHP-H1 arrived today. I hooked it up to my TV and preamp, updated the firmware, and put a disc from my Dark Skies DVD set in as a video torture test. It was a lower-budget alien invasion series (often considered a ripoff of The X-Files) from the mid-90s that was probably shot on video. It looked pretty rough at first... the picture was really dark (the episode started off with a night scene) and skin tones looked unnatural with some jaggies thrown in (interlacing?). I played around with the settings but mostly turned any enhancement stuff off. I suspect the jaggies are part of a poor DVD transfer rather than an interlaced signal. If you turn all the noise reduction stuff on, the picture starts to look like a cartoon.
Then I put in a Blu-ray of The Musketeers (BBC, third season)... much better. I've gotten so used to the excellent Blu-ray playback from my PS3 that I took it for granted. The picture looked a little dark, but I was tired of messing around with settings so I just watched the episode with stock settings. I did notice the sound had nicer separation than the PS3's audio.
Having done a basic test of video, I put The Cars SACD from Mobile Fidelity into the player... this was the big test. I've listened to this album many times. It's not hi-fi, but it's easy to compare. There's definitely more detail there. The next disc was from Alison Krauss + Union Station's Live... great stuff. Similar results: more detail, more space, more texture.
There may be something to this SACD technology. I'll have to do more audio testing with my headphones, as my stereo experiments probably disturbed my neighbors. Worth it.
I'm using an AmazonBasics HDMI cable and 47 Laboratory Stratos cable with Eichmann Bullet Plug RCA terminations.
