Let's just remember that this is MP3 sound, so the caution is required. I had heard Paco de Lucia live play that custom Conde that I mentioned. It was absolutely incredible instrument. I never heard Montero guitar.
Rinpoche, I think, has an excellent hearing, and this presents a problem of a sort. She wants a combination of VAC and Rowland sound. Gonzalez guitar represents a kind of successful fusion of the two with a tilt, to my ear, to Montero. So...this is tough. We are also talking only about digital source, as I understand, no turntable or reel to reel deck. Plus the ability to play movies well. Double tough.
I do have an impression that Rinpoche really likes the way Rowland controls the speakers even if it doesn't quite have the VAC's 'seductive magic'. Only she herself can choose, we did our best to help.
