Due to lifestyle limitations my NAC252 shares a glass shelf with my NDX2, with around 4cm space between them.
I think it sounds “glassy”…
I don’t have an option to replace the rack, etc. at present, I either need to stack two devices, or place two side by side. I could move things around so the SC shares a shelf with NDX2 if that would be better. Or perhaps try some isolation feet.
Can only do what you can. Accommodating is something that plagues is all. Haven’t tried personally but people speak highly of the Quadraspire feet where racking and separation is an issue.
Both the NAC and the ND are sensitive to positioning. If you can, put them next to each other rather than stacked on top of each other, the power supply in the NDX (assuming it’s not being powered by an external PSU) is most likely interacting with the analogue output stage on the NAC and giving the undesired colouration you describe. Ultimately this level of equipment is designed to work optimally when placed on a dedicated shelf and as far from the power supply driving it (and that of other equipment) as cabling lengths allow, splitting the electronics from their power supplies across two racks isn’t uncommon at this level within the Classic series.
I’ve not tried their equipment feet but do use IsoAcoustics feet on my speakers with positive results.
I use Stillpoint Ultra Mini under most of my gear, including my 252. I’ve found they bring a nice uplift in clarity without harming the sound in any way. Fraim wasn’t acceptable on domestic harmony grounds so I compromised on Blok racks which have glass shelves and although well made have nothing in the way of Isolation. I feel with the Stillpoints as isolation I’m not giving much, if anything, away to Fraim.
I used to position a Nova on a glass shelf and tried the Quadraspire reference feet. Made a big difference to sound quality although they were expensive.
Quadraspire do a demonstration case containing all three isolation variants.
I found all three made a difference.
If you do go ahead and try them don’t put them under your equipment feet but put them directly under the casing of your equipment.
Great advice, thanks all. These isolating feet are so expensive, especially as I’m likely to need 8 (252 and NDX2), I like the idea of seeing if I can try some from my dealer first - thanks again!
It’s far easier to level three points than four. My Xerxes has three suspension points by design. I’d be more concerned though that Naim designed the unit with four feet and the possibility that altering that may induce stresses on the chassis and components.
hi how did you set them up (as mentioned 2 front and 1 at back??) home demo-ing them now not been bothered so far when putting them under the naim box feet on my SVT bamboo rack
Two at the front and one at the back. And the case sits directly on them, not the feet. Under the Supercaps and 250s I have two under the transformer side and one under the middle of the opposite side.
For me with 252 I have two Orea bronze at front and one in middle at back. For the NDX2 and SuperCap I use Four bronze, one in each corner. Looking at the ISOAcoustics graphs this looks about optimum. For 250 I have two indigo ones the right side by the transformer and one in the middle. With my Oppo 203 I have three graphite as per 252. All directly touching case as more effective and better looking than under feet. Will try and sort a picture. Initially had four indigo under 250 but sound had more punch with three.
