Peter, sure. What I mean is that the opening up of the top end of the Straingauge via the RWA BL batt psu is resulting in an amazing "lightness" to music that I think can only now be achieved with crystalline extension of the treble.
If this was at the expense of a lack of power, bass extension, warmth and earthy tone of the lower frequencies, I would have been unhappy with a "wispy" quality. But these positive bass characteristics are all present, and in fact enhanced, leading to an amazing improvement top to bottom. So "ethereal" can co-exist with "grounded". As can "wispy" and "insubstantial/insipid".
