Yes, glowing is the exact word, as the Momentum HD also sounds glowing - the performers shine illuminated a soft warm light, with none of the typical artifacts of many SS preamplifiers. Listening to some old opera CDs (not in my system) going through it I found that CD voices can sound as fleshed and liquid as the best LPs of the 60's through tubes. It was a real surprise.
Although some people will consider that the Momentum HD was just a small incremental evolution over the old model, IMHO subjectively it was a gargantuan jump. I found curious that Jason Serinus also highlighted these aspects I had reported in WBF a few months ago.
