I got hold of a Flatcap XS and wired it up right to my Nait XS Amp. I turned on the Flatcap XS first, then the Amp (don’t really get why the new external power supply isn’t now the ‘power source’ for the amp and you have to still turn both on).
It isn’t exactly obvious it is doing anything. E.g. a little LED saying ‘external power supply working’ on the Amp would be a nice touch. How can you tell? Obviously each device is on from the Naim glow, but that’s not proof they are working together.
I know ‘listening’ is one obvious answer. But I’m suspicious of subjective analysis and it hardly seems the scientific way to tell something is on and working as it should.
The Nait needs to be plugged in to the mains as the Flatcap only powers the preamp part, not the power amp. If you have removed the link plug and connected the Flatcap using two Snaic leads, a four pin and a five pin, and it is working, then the Flatcap is working, otherwise you’d have no sound.
It is only your ears that can determine if the addition of a Flatcap is worthwhile, and presumably you tried it before buying.
This was my immediate reaction. I’ve been here a few times at a number of levels. The difference has never been subtle and always been positive. It appears that this upgrade isn’t working, either because the PS is not operating as intended, or it’s just not a good upgrade in this particular instance, which is unlikely but not impossible, I guess.
I had very poor results when I put a flatcap xs on my nait xs2
To be honest…I never rated the flatcap in the slightest…
I tried a new cable that “linked” the audio without sending it through the flatcap and that was slightly better
Save your money and buy a supernait 2 or 3!!
I’ve never auditioned any Naim kit in my home. Listened to some at the dealer. And the first gen Supernait that I listened to at the dealer was the most disappointing kit I’ve owned. I was so happy to move that on.
No issues with any Naim power supplies not making a distinct and noticeable improvement on the equipment they were hooked up to. Flatcap, HC, HC2, XPS, SC2, all great.
Also the same here…was very dubious about the whole power supply shenanigans until my dealer put a flatcap on my cd5. Took about 20 seconds to make the decision that it was staying. Definitely the start of a slippery slope some 10 years or so ago! Don’t even get me started when he then convinced me to try a Powerline on the CD5 as well…
I can’t think of any Naim component I’ve used that didn’t have a PSU powering it. Even the stageline used a HiCap2 to boost it. Naim are very canny marketeers!
