NAPSC tip

Posted by: dave simpson on 28 June 2003

Not sure which one of these moves made the difference but....

If you're a NAPSC user--do not forget the NAPSC's power umbilical when performing your plug-cleaning chores (as I usually do). Either the action of plugging/unplugging the umbilical into my 102 *and/or* increasing the distance of separation between the NAPSC's AC cord and it's output umbilical (cable that connects into my 102) made a significant difference to the sound (more relaxed, more low-level detail, less distortion). I previously positioned my NAPSC as far away from the rest of the gear as possible *but* at the expense of the NAPSC's two cables (AC and output cables) running parallel and with only three inches of separation for most of their length. As I cleaned the NAPSC umbilical by plugging/unplugging it several times, I re-positioned the unit and it's two cables so they have two feet of separation over most of their run. What a difference these simple adjustments made--and all at no cost!

In a nutshell, I've found the best setup for my NAPSC as follows:

#1. As far away from any other electrical device as possible without compromising item #2 below.

#2. Sacrifice a little distance if necessary in order to maintain as much distance (and over as much length) between the two NAPSC cables (the AC and output cables).

#3. Don't forget the NAPSC plugs (output as well as AC!) during your cleaning routine.

#4. If you're a follower of the *single*, dedicated hifi AC circuit crowd (as I am), plug the NAPSC into the *same* circuit as the rest of your hifi *but* at the end of the power strip and away from the other AC plugs. For example, my AC plug sequence in a Wiremold power strip is : (mains breaker) 250, Hicap, CDPS, NAT101, empty, empty, empty, empty, NAPSC, (end of strip).

happy listening,

Dave,

In #4, why not CDPS,Hicap,250....etc. (i.e. source first heirarchy). Presumably you have found it sounds better powering the 250 rather than the CDPS in the nearest AC plug socket, or have I misunderstood?

Exactly Paul,

I (and many others) prefer the "reverse" hierarchy position. Slightly less detail but a lot more groove ;-)
