G’day Griot,
This may confuse things for you though I hope not to. My amplifier is an XS2 and if I had my time over again with what I know now I would have purchased an SN2 at the time. Though as a newb to Naim and only wanting a lovely sounding reliable amplifier and a price my dear wife would be happy with I chose the XS2.
Later down the track came the CD5 XS and an FCXS at the same time. I felt this system was now lagging and the upgrade path tempted me to go for separates which I have probably squeezed all the information from members on this forum. In the end, I had my Celestion SL6Si speakers refurbished. Gone is the aluminum dome tweeter replaced by a ribbon tweeter and out with the PVC woofer and replaced with a kevlar woofer. Again I squeezed all the information the patient members of this forum could provide and knowledgable comments were made. Though alas my wallet could not afford new speakers or any other upgrades even though I dreamt of such.
In conclusion, the money spent on the speaker’s refurbishment was the best money spent. I can now hear cymbals shimmer, and ring out which was not present on the dome aluminum tweeters. Did I hear any difference in the bass? I am not sure, though I am very happy with the refurbishment, new cross-over designs were engineered and implemented. The soundstage is beautiful and dynamic.
I am a bit of a technical guy and can become lost in the numbers of frequency responses and figures of this nature, headroom is another. Having crunched all the numbers and materials used I now sit back and enjoy the music. Upgrade paths are history. I am where I am at and very happy with what I could afford. My amplifier just barely meets the required headroom for 84dB speakers, I think it may even just fall short by a couple of decimal points of a watt. I am no longer bothered by that. It is what it is and is very enjoyable.
After peeking at your HIFI equipment list I see that you own pair of Focal Chora 826 speakers. Having never heard them I do see that they are made of modern elements and designs. If you can hear cymbals shimmer and tight dynamic music you may not have to go any further and be content with what you have. I also see that these speakers have received many awards for 2022. They are high in efficiency at 91dB SPL and would be no load for the XS3. My personal opinion would be to stay where you are. Though it is your wallet, money, and ears.
Possibly an ND5XS is the next item to purchase, which is what I am currently mulling over, though digital technology is not my forte as such with setting up digital networks.
Warm regards,
Mitch.
