I would ditch the MIT cables for something else. I own a pair of Ayre V-3's biamped to a pair of Legacy Audio Focus 20/20's using Discovery Essential speaker cable. This is a very natural sounding (no Hi-Fi glare, excess siblance, etc.) sounding combo. Analysis Plus Oval 8 speaker cables may work well also. I have found MIT cables to sound more "Hi-Fi" and less musically natural with the Ayre gear. I feel you have an excellent front end and amplification match for the Dyns. Try cables first. The ones mentioned above are not terribly expensive, especially the Analysis Plus line.
Replace Dynaudio 1.8 w/ AP Virgo or Tempo?
I have the Dynaudio 1.8mkII with Ayre K3x,V5x(coming shortly) and Meridian 508.24 and MIT T2's all around. It's not that I don't enjoy the Dyns or that they are a poor system match, I just feel that the Virgo or Tempo will give me better soundstaging, transparency, and probably a little less mid-bass coloration. Anyone care to comment if this is a worthwhile upgrade. Is it a lateral move? Yes, I probably will be trading off some strengths, weaknesses for others. But the question is whether or not I would get more overall strengths in the trade. Before you go there, I don't think the Avanti's will be within my reach, even used, financially.
