Catching up with Audio/Video
In the 1960s I was fascinated with technology, and when colour TV came to Canada (years after the US!), the next big breakthrough was to be high-definiiton TV, and I recall it being discussed in the press. That may have been the NHK system demo’ed in 1969 described in this article. But for technical reasons the technology stagnated and did not become widely available until this century.
I also remember listening to my first FM broadcast in the 60′s on a portable radio, and was capitivated by the richness, relative to AM. And I recall clearly when my brother bought his first cheapo stereo system and we listened to the soundtrack from 2001, A Space Odyssey. I was amazed at the depth of the sound.
In the 70s I often helped friends purchase high-quality stereo systems, and knew a fair amount about the technology.
Despite this I never purchased a good-quality system for myself. So recently I decided it was time to investigate audio and video technology and get myself a decent system. I quickly discovered that audiophile systems were well out of my price range, as was the latest in HDTV. But with minor compromises, the cost could be brought down dramatically. So here’s what I purchased:
- Panasonic 42″ 1080p TH42PZ800 plasma HDTV
- Pace TDC-775D PVR (only choice with local cable company)
- Panasonic BD50 BluRay player (now superseded by the BD55)
- Yamaha RXV-1800 receiver (good price as the RXV-1900 is now available)
- Grado SR-2 headphones
- Panasonic DMR-EZ48V DVD recorder (for transcribing old VHS and Hi-8 video tapes)
And here’s my impressions:
- The richness and clarity of the TV are amazing.
- The colour depth of the TV is very poor, looks like 16 bit colour, resulting in very visible banding on graduated colour areas, whether from BD, computer or cable. I went back to the store and looked at many plasma and LCD TVs, indeed this is a chronic problem with plasma, which I didn’t find noted anywhere in reviews. How odd. Of course, the newest, very expensive TVs (like $9k) don’t have this problem. LCD TVs perform much better than plasma on colour depth.
- The compression needed for cable HDTV results in massive pixellation on movement, it’s tolerable, but I think they (at least the local cable company) has gone overboard on compression.
- Flight Simulator X looks fantastic on a 42″ plasma, and performance is quite good.
- There is no hiss at all from the receiver. Zero. Amazing. Overall the receiver specs are better than the best studio equipment of the 70s.
- The Blu-Ray player takes forever to start up! But movies look great.
- The headphones are amazing.
- Amazingly, neither of the DVD players can read .jpg images over 1Mb in size, something that aged DVD players can do. A big hole in Panasonic’s capability. I have to drive slide shows from the computer.
- I once tested the Shaw digital audio channels because the sounded so crappy, and found they rolled off around 8kHz. However either my system sucked or they’ve changed the quality, because now they sound great. Definitely wide-response, although there still is some distortion on very low frequencies at times. That may be the fault of the audio stream providers, who knows.
Now astute readers will have noted something missing: speakers. Those I’m going to take my time with and save my nickels, as they are the most critical part of the system. Meanwhile, the place I’m renting has some old Technics speakers that sound ok: they are missing the low end, but capture the tinkly highs adequately. And clarity is good.
So I’ve caught up a bit, and am satisfied with what I have.
