Very sad news. A small anecdote, which says something about the man - I bought a Vitale preamp from Stoneaudio circa 2003, and one day a few weeks after its arrival there was a funny smell. On investigation, I found that one of the small transformers inside the Vitale looked burnt. I contacted Stoneaudio, who arranged for the amp to be collected - leave it with us and we'll get it sorted, that kind of thing. (I might mis-remember the exact pattern of events, but I think it was something like that.) Anyway, I was somewhat surprised when within a few days the phone rang. "Glenn Croft here. Sorry about all this, the transformer must have been faulty, I'll pop a new one in", or words to that effect. A few days later the amp duly returned, with a rather snazzy-looking small toroidal transformer in place of the rather ordinary non-toroidal one that had started to go up in smoke. Thank you Glenn, for the great designs and for the personal touch. You held yourself to high standards, and we were the lucky beneficiaries. RIP.
