I've tried several amps on my Cornwall IVs including the McIntosh MC275 VI, my friend's Rogue Stereo 100 with Dark upgrades and BoyuuRange A50 MKIII 300B, and my own Audio By Van Alstine 600R hybrid amp. 600R bested all of them until I tried my Enleum 23R. I've had my 23R since mid December and I couldn't be happier with it driving my CWIV.
If I could use one word to describe the sound of the 23R it would be organic. It's tubelike character is also very transparent, fast and dynamic without ever being fatiguing. It's only 25 watts/ch and it's a world class headphone amp as well mating with my Susvara, Abyss 1266TC, Focal Utopia and ZMF Verite open. Enleum is a new company formed by the former head of Bakoon International. The amp has only been out for about 4 months but it's already been reviewed by 6 Moons, Darko on Youtube, Jason Kennedy and several others. All the reviews have been very positive and in summary, they say the 23R is a fantastic amp for easy to drive sensitive speakers. My CWIVs are rated at 102dB and they easily drive them with excellent dynamics and transparency.
