In answer to the OP's original question, I am not sure why Linn would be singled out for discussion on here as , generally speaking, Linn and Naim customers are looking for different things in HiFi, other than of course Hi(gh) Fi(delity).
I too was a long-time Linn owner with my beloved LP12 but that was using Naim (and other) amplification. The question the OP raises does however prompt me to think why I have an all Naim system (well source & amplification) and why I never went down the Linn route. The primary reason is, for me, the addictive sound signature and engaging nature of Naim gear.
I recently listened to the Kudos 505 speakers fronted by a Linn streamer and Linn active amplification, a speaker I have heard a couple of times previously with Naim sources and amplification. There was no comparison. Linn - clean, succinct but ultimately un-engaging. Naim - impactful, visceral, engaging and, yes, probably OTT for some, but never, never boring.
I would always go for attention-grabbing, engaging, with an emotional connection and, yes, possibly unfaithful, than clean, lean and ultimately unemotional.
Speak to a Linn owner and you will get a diametrically opposed, and equally valid opinion.
