ok, based on my research, if the input impedance of power amp is not high enough (10x of the output impedance of preamp), then the system will be more prone to sonic distortion. This is because there is a reduction of signal from preamp to power amp. And the reduction is a function of frequency. So, the reduction is not a constant that can be balanced out by turning up the volume knob. That means, the sonic is changed, whether it is good or bad will then be subjective, and depends on each unit, I guess.
Some impression on Zu Omen Definition
I just pick up a pair of Zu Omen Definition, and I have mixed feelings. It sound very different from my B&W.
First of all, the height of the sound. For my B&W, the sound is a bit higher than my ear level. But for the Zu, it is the same or a bit lower than my ear level. This sounds a bit weird. Because usually the singer will be on a stage, so, it is more natural to expect the sound is higher from my ear level.
Secondly is the depth. For my B&W, the singer is behind the speaker plane. For the Zu, the singer is very forward. It almost feel it is in front of the speaker plane. I don't know which way is better. Due to this difference, for the 30 mins or so .. I feel very weird listening to Zu.
Why would 2 speakers have so much different in presentation? The zu is much taller than the B&W, so, I expect it will project a bigger soundstage. And usually the sound stage is behind the speaker. But with the height and forward sounding, I can't say produce a big sound stage. Or can I say it produce a sound stage in front of the speaker plane, and I need to sit back further?
