Amplified are quite better but the extra money is not worth it, since I'll probably have to buy a receiver. Speakers are 200Watt RMS.
That would really be the best way to go for sound quality. The subwoofer needs to be amplified because receivers aren't designed to power them, only the other 5 or 7. The cheapest good receivers here for 7.1 are Yamaha 565, Onkyo 607. 5.1 are the Yamaha 465, Onkyo 507. 5.1 is going to be maybe 100€ cheaper. Unfortunately probably 400€ + for 7.1.
Also what's really the difference between HDMI PCM and Optical Out PCM? Aren't they both Digital Formats? Also, consider that an HDMI cable also offers some resistance to the electric signal, when an Optical Cable doesn't, since it uses a 100% reflection ratio. I never understand why people say HDMI audio is better :S
- Resistance is irrelevant, because these cables are carrying digital data, not an analog signal. Basically it is a voltage vs. time wave. Even if the resistance causes voltage to drop, as long as it is above a certain threshold for the receiving chip to still recognize a "1" as a "1" (> some voltage relative to ground), and "0" as a "0", it simply doesn't matter. It only would have effect for extremely long cables, like 15m+. Digital transmission is robust against signal degradation, it remains "perfect" until the point where you start getting audio dropouts.
- The reason HDMI is better is because it supports more channels of audio. It will carry 7.1 channels of uncompressed PCM, @ up to 24 bit, 192 kHz sampling rate, while the optical only designed to carry 2 channels of PCM. Both can carry the older lossy compression 5.1 Dolby Digital, DTS formats. But only HDMI will carry the higher bitrate lossless compression TrueHD, DTS-HD/MA formats.
I think in theory they could have still used optical for the newer formats, if they changed the transmission+receiving chips, but manufacturers were moving to HDMI to carry video also, plus there was pressure from studios to have copy-protection measures.
Ahh Home Cinema is quite expensive... Don't know how you guys can spend so much
on this but it does feel great afterwards...
Yes it can be. One mitigating factor is that the equipment can last a very long time. I used my previous receiver for 10 years. My speakers I haven't changed in almost 15 years, except for subwoofer I replaced because of failed amplifier (that I used 10 years). Also, I choose to spend money on this TV/movie watching equipment, instead of buying more expensive automobiles. Cars are more money than this :).
It's also cheaper than to actually go to the theater & pay admission to watch movies, if you like to watch many movies per year.
