Along the way, the voltage is stablised to whatever level you choose to set and distortion of the AC sinewave is drastically reduced. In the shop at Manchester, incoming distortion is around 2 to 2.5%. Here at home it seems to be more in the 1.5 to 1.9% range. Initially the higher distortion was seen during the day, but since the solar panels were installed and on brighter days, daytime incoming distortion seems to be very similar to evenings. Output distortion tends to around the 0.1%, so a major reduction.
In terms of effect on the system, well, I don't think it has any effect on the emotional capabilities of the system but it does improve some of the more "hifi" aspects. There's a definite improvement in imaging stability - vagueness about where an instrument might be is reduced, and it stays there. Also, everything seems to be "freed up" from the speakers - a wider, more open soundstage across the room and front to back too. There may be a touch more fine detail too, as a result (I presume) of a reduction of background noise. But its the imaging and soundstage that makes the biggest impact.
The device has a front panel display that shows information about incomings and outgoings.
|All outputs switched off|
|Just the streamer powered up|
|Running at volume level 55 for streamer, pre-amp and power amps|
Its also possible to monitor through a web interface:
|Full online screenshot showing labelling of the output sockets. System is on but idle here and is only consuming 105W|
|Volume level 30 shows an additional 30W or so of consumption|
|Volume level 50 doesn't use much more power|
|Volume level 60 (the sort of volume I usually use when doing "proper" listening)|
