NAPSC UPGRADE

Tamarin posted:

You can very carefully score, and peel back the REL high level cable casing, in order to expose sufficient lengths of the red/black/yellow inner wires, to allow for greater speaker separation. Just be sure that when you score the outer casing, you don't go all the way through (possibly damaging the inner wires). Once properly scored, you can then peel back the outer casing. If you're not comfortable doing this, any competent electrician or electronics service technician can do it for you.

The REL black negative wire only needs to go to one of your negative speaker terminals. Specifically as follows...

Right speaker: REL red to red/positive speaker terminal. REL black to black/negative speaker terminal.

Left speaker: REL yellow to red/positive speaker terminal.

 

Thanks spot on

l glad someone told me that connection to the power amp is different from connecting to the speaker terminals, l wouldn't of worked that one out in a million years--Electricity moves in mysterious ways!!!!

I think that some members who don't agree with me are actually agreeing without realising!

Someone said "its got more resolution and definition" with NAPC

l agree with this, its exactly what l'm saying that's what the NAPC does but if Paul McCartney wanted more Res & Def he would have adjusted his tone controls appropriately. My definitive opinion is  Bass especially is more real without the NAPC and nothing to do with taste. My speakers have 12" bass drivers and 12" ABR which probably means l can hear how it is more than most as most bass amps have 15" drivers. When l owned a Naim DAC a few years back l added a 555PS which hardened up the sound like the NAPC. I was told the XP2 used on CDS3 would have been a better match. l don't think "upgrades" are a definitive improvement, my ears decide, always. 

I have just been informed by WITCH HAT that l will need a hi cap to connect my Subwoofer but if this alters the tone balance l might have new problems

I am resurrecting this thread and repeating this same remark I have posted earlier in May - If you feel the 202 to sound better without the NAPSC then let it be. There is no right or wrong in this game as it is mostly down to personal preferences. 

I recently tried listening to the 202/200 without the NAPSC and power supply. It's the first time in 9+ years I am doing this as I always had the 202/200 connected with both NAPSC and power supply. I am not using a Naim Hicap with the 202 so I couldn't mention the name of that power supply.

Long story short, the 202/200 does sound different without both NAPSC and power supply. In my case, it's a bit different as I have both NAPSC and PSU connected to the 202/200 whereas you only have the NAPSC connected. Running the 202/200 bare, the bass is less controlled and free as a bird. In translation, it may be what you have described with the bass sounding more real.

I will reconnect the NAPSC to the 202/200 some day, followed by the power supply. The 202/200 is my secondary setup so expectations are not high with the system. That partly explains why the system still sounds great without the NAPSC and power supply. I would be more inclined to think that the 202/200 sounds different from the 202/200/NAPSC/Hicap rather than one sounding better than the other although the general consensus is the latter is sonically superior.

Bottomline - if you think the 202/200 sounds better without the NAPSC opinions from others do not matter.

Enjoy~

 

By the way, I nearly gave up on running the 202/200 bare when I played the first track on the system. There was a slight buzzing sound from the speakers when the system was fired up from cold. I thought there might be a glitch with the amps as they have always been run with both NAPSC and power supply throughout the years, 9 years to be exact. Perhaps they just need the NAPSC (or power supply) to stop making the buzzing sound I thought. Fortunately, the buzzing from speakers disappeared after 4 to 5 minutes with the music still playing.

With respect to sound quality, it's not really that bad without the NAPSC and power supply. But as I have said earlier, expectations are low with the system. One thing is for sure though, music sounded a bit different when the NAPSC (and power supply) are not connected to the system.
