My system is powered by two P10s (multiwave 6). It’s a large active system using a digital crossover and Directstreams (seniors). I’ve discovered that if I run a couple of long Cleans (i.e. approx 2 * 1 minute) the system is very sharp/clear (good) compared with letting it run for a few sessions, after which it gets relatively congested sounding (bad). The components that have obviously analogue features are:
2 * BHK250s - driving tweeters/mids
1 * Crown CE4000 - running bass - this amp has an internal switch mode power supply (otherwise it’d be excessively heavy)
1 * Wyred4Sound PS1 linear power supply, driving four W4S coax reclockers and one W4S USB reclocker. This is fitted with four 9V 1amp outputs.
3 * Directstream senior for tweeter/mid/bass
The more ‘digital’ components are:
DEQX HDP-5 digital crossover providing 3 * 96/24 coax outputs
1 * Chord M-Scaler - upscales 44.1/16 to 88.2/24 fed from a WFS Recovery USB reclocker (the 88.2/16 output gets upscaled to 96/24 by one of the W4S Remedy reclockers). The M-Scaler is not cheap but nevertheless has a switch mode power supply (which Chord must be happy with)
Melco N1A Server outputting ripped CDs via USB to the M-Scaler
Obviously I could turn zones off and by a process of elimination eventually conclude which parts of the system benefit most from a Clean - this would take me several weeks, hence I’m asking PSA for advice.
BTW, the procedure I use when I power down the system is to use the DS remote to turn the DSs off. I then turn the BHKs off from their front panel switches and I turn the power off to the Melco from it’s front panel switch - I let the Melco power down its drives etc which takes a few seconds (I do this because it has two disc drives in it and don’t want to risk a disk failure). Finally i turn off a P10 from its front panel switch - a 12v trigger powers down the other P10. Zones get their power removed in sequence, e.g. the amps are powered off first.
If the system is congested and I do a clean it seems at least a couple of db louder. I suspect it’s the Directstreams that benefit most from the clean rather than, say, the BHK250s or the Crown. I’ve no idea how much the W4S PS-1 would change after a clean. I presume that the more digital components, e.g. the DEQX crossover (coax in, three coax out) and the Chord M-Scaler (USB in, coax out) wouldn’t benefit from the clean function - is that correct?.
[one final question, do the newer regenerators (P12/P15/P20/PP3) do anything that can help transformers not to magnetise, e.g. provide power to zones at a particular time within the output cycle]
Thanks a lot, Dan.
Update 11 June. I’ve been powering off the entire system after every session because the power draw of all the amps etc in standby is quite a lot - I sometimes go several days between listening sessions. Which components are likely to dislike this treatment?.
