I do not try to compare models, but just to get an impression of what the difference in sound is. I myself have a McIntosh C200/MC402 combo, which offers excellent mids, deep, life-like bass (very important to me!), natural highs, but not the last degree in resolution. I just wonder about Spectral, which I have never listened too, but which is supposed to sound excellent as well. I am just out for impressions and descriptions of people who have done so.
