I’ve owned an older Plinius Class A power amp and it’s very nice indeed. Great sound and excellent build quality (like a tank) but I had to let it go as the amp did not match my loudspeakers at that time.
The Naim Nait XS may sound nice but I don’t think it’s the equivalent of the Plinius Hautonga in both price and performance. It might be worthwhile to audition the Naim Supernait 2 as this one is more comparable to the Hautonga with a more powerful and dynamic presentation. Other options include Exposure 3010S2-D and Densen B150. Ultimately the choice will be dependent your listening taste apart from the speakers that will be used with the amp.
