I am so going to enjoy watching this thread as it grows & grows!
Our non-Naim amps also use balanced inputs and interconnects, so we have been (still are?) on a similar journey.
By far the best value we’ve found for our amplifier has been Designacable’s Mogami 2549 balanced interconnects with Neutrik XLR connectors for £50 a pair, delivered. They manage to maintain music’s sense of rhythm & timing, something that most of the posh ones lose along the way. They are not as smooth & refined as the £1,000+ ones but they aren’t so far off. Hence, they are a brilliant value baseline or reference for the posh ones.
Posh ones we’ve tried include:
Witch Hat Morgana - a special, balanced version of Morgana, after great success with their single ended DIN-XLR cables between the NAC52 & NAP135s. Fat, bloated, slow bass. Not good at all. Got rid of them quickly, once I’d allowed enough time to hear that they weren’t getting any better after burn-in.
Siltech 770i - Wow, noise floor just fell away, lovely warm, endearing round slightly dark sound, draws you in with effortless, lifelike detail. Huge musical image between and around the speakers, gosh, lovely. Phenomenal but so slow, timing’s just gone, no foot tapping anymore.
Nordost Heimdahl - A breath of life, vibrancy, energy and rhythm after the Siltech. Much more like it and leaves the Mogami way behind. Just a bit bright and fatiguing.
Atlas Mavros - Better than the Mogami 2549 in all respects but only incrementally so.
Townshend F1 Fractal - Bettered Atlas Mavros XLR when I compared. Phenomenal resolution & perfect timing/rhythm when between pre & power amps. They are always a bit lean/thin/cold/brightly lit sounding. Not harsh or distorted, just a bit lean/thin. Overall very good and I still have a pair of these.
Atlas Asimi - Utterly delicious and beautiful sounding. Eye-wateringly expensive.
Transparent Plus & Transparent Super - Big, fat, bulky, stiff and awkward as hell to fit in a restricted space. Sound brilliant between the pre & power, simply natural. Wanted to hate them ended up buying the Super.
It will be interesting to learn of others’ experiences with the new classic Naim amps.
