Incorrect. With active system the left and right channels for the amp is isolated, driving less electrical noise. Also the amp is mounted right in the speaker so you don't go though extra cabling to connect. The Passive system is bad because there is more noise is driven from the amplifier in the receiver. It doesn't end there, you collect even more noise running speaker cables from amp to the speakers. More number of wiring / connections = worse sound quality It gives you more opportunity to collect more noise.

That's how much it costs to fill up a gas tank. For that price it's not a bad buy for the Pio at all...

Isn't that a contradictory statement? If the amps are isolated it would be 1 amp per speaker, all the amps together would mean they are not isolated biggrin.gif

Active speakers do have higher noise level than passive speakers though. There is considerable DSP noise from using active crossovers, there's no way around it. Even super high end $10,000 DEQX active crossovers will have far higher noise level than $100 passive home theater speakers. This is a well-known, measurable, and reviewed issue with active crossovers.

On the flip side, going active means you need less power to achieve a high SPL due to less power loss through crossovers, and active crossovers can have very high db/octave slopes, up to 300dB/octave in modern designs compared to 24db/octave with passive designs, which means more better dynamics and less beaming. But SNR and noise levels is definitely not an advantage for active designs unless you have a seriously defective amplifier.

Separating amps for each speakers is better as they drive less electrical noise. When you have one big amplifier in the passive system there will be more electrical noise. Not to mention, the heat will increase further. It will also infect the rest of the circuit system with noise that includes onboard DAC in the receiver. Actually they infect each other. It's a noise city. With the Active, you have separate amps you can connect the power cable to outlet farther away from the other amp. The larger the amp, and the more power draw in the amplifier to support multiple channels, the more noise they will be infested with.

I don't have noise issue. Are you referring to hiss / hum issues with the active speakers? That depends on the quality, design of the speaker system and your audio interconnects. Active systems can definitely suffer from electrical noise and RFI/EMI just like the Passives do, but they are less affected with the Active system because they produce less noise. The best way to eliminate hiss / hum is to get better interconnects. It worked for me.

In the end, with Active system you get the most naked (transparent) sound, with more details. With cable upgrade the sound improves even much greater. You can get improvement with the Passive's too with such upgrade, but not as good as the Active.

You don't need $10k active speakers to get better sound, the cheaper ones will do fine. Just gotta get the right ones and that synergize with the rest of your system.
