While there is much air and transparancy with the XA777es, what I'm missing is "ambient glow." (I will leave it to CD-player critics to describe what *that* is.) I've also noticed that their isn't as much room interaction with the Sony as opposed to the Marantz SA14 ver. 2. The Marantz seems to outline and heighten chords more than the Sony--whether this is real or not, I don't know, but the Marantz was certainly more seductive because of it, though I think it led to some slight muddiness in tutti orchestral passages that led me to put some damping treatment (towels, ha ha) on the walls. Average to excellent recordings, with a good capturing of ambience and glow to begin with, sound great on the Sony. The Marantz salvaged recordings that were more distant, bringing out more ambience, but not more 'line' than the Sony. I hope this makes sense. It's safe to say that the Sony brings out more of the musical line, (leaving the responsiblity of capturing ambience and sensuality to the recording crew), while the Marantz brought out more of the verticle relationships (interaction between notes in a chord and between instruments). Which is better? A matter of taste: Some conductors are more line/melody-oriented, (logical), believing that the sensuousness will just fall into place while keeping the composer's ideas in tact; other conductors are more sensuously oriented, (very interested in chord-play), just barely keeping the musical line together. I happen to prefer that latter in the rare cases when it works.
