Like Larryi I'll recomend an Art Audio amp, the Carissa. I'm running it with my speakers that are 98db efficient and have a 12" woofer with horn mid and tweeter. It's an 845 SET with 16 watts. There is an excellent review by John Potis on 6moons. The Carissa along with my deHavilland UltraVerve sound wonderful. Amazing resolution with body weight and warmth. I wish I could better explain how great it sounds but I'll leave that up to the reviewers. Good luck in your search. Also, as good as the deHavilland is you should also check out their 845 SET the Ios. I look forward to hearing it someday.
Cheers
