AudioControl amp/pre amp

I don't know class H well at all and have never listened to it.  That said, I understand that it works similar to a class D.  The class H keeps it in analog, where the D is digital, I believe?.  That said, I have listened to class D and use in one of my every day systems.  Love that it is a small unit that doesn't generate heat.  However, it is lacking in warmth, musicality and can come across bright.  I would be tempted to try your speakers with a different type of amplifier.  Class A or class AB.  I have other speakers that I hooked up to a class D that I have hooked to class A and class AB and found a huge difference.  The class D, while it provided every frequency and hit all the same notes, sounded void of music.  Just my opinion.  Don't know where you live or how you purchased but you might see if you can listen to your speakers with a different type of amp and see if that is the problem.  I did find a review where someone listened to the Monitor Audio Gold 200 using a Bryston B135 SST and reviewed very favorably.  Good luck. 

Thank you for your response. Your comments describe what I feel is missing from my current system. One of the positive comments one hears about the Monitor Audio speakers is their musicality. The Class H amp just doesn’t seem to be bringing out their best.
