The Elites are also a bit warm, i was very impressed with the imaging, detail ,speed, and bass out of the HPA4 compared to direct Dave. The fact that it sounded a bit leaner gave me a bit of pause.I've not had the opportunity to try the Enleum myself unfortunately but people whose ears I trust all adore it.
Apparently it's definitely a warmer leaning amp, so be aware of that in case it's not your thing, but it seems to be pretty universally liked.
If wanting to save space, consider a Ferrum OOR/HYPSOS combo perhaps.
Both the Enleum and the Ferrum are a tough sell unheard for me... Especially people testing them only seem to care about how well they drive Susvara, and i'm in a completely different use case. The HPA4 is way too powerful for the Elites as it is, I listen below 50% volume.
