In the end, the Liquid Glass is all about giving listeners sonic options. During my listening tests I tried the six valve types cited above and the honest truth is that, through the Liquid Glass, each had certain distinctive sonic benefits to offer, meaning there really was no sonically ‘right’ or ‘wrong’ choice. Like a fair and impartial judge, the amp effortlessly revealed different aspects of the music that one valve type (or brand) might handle better than another. This ability to look honestly and deeply into the mysteries of musical textures, timbres, transient sounds, and dynamics is what makes the Liquid Glass so special and, frankly, so endlessly entertaining.
