This is gut-wrenching. I don't think I've ever shed a tear about audio before. Except when I sheared the diamond off my rare Garrett Bros Decca by not locking the armrest. Al has always been a gentleman on this forum. Not only because he is a kind and generous soul, but because he knows his stuff. He never gets ruffled by bombast and conjecture. He is the real deal. The fresh air of knowledge and wisdom. There is no disputing the facts, especially as his explanations are thorough and written in a manner us mere mortals can comprehend. Al, we will miss you. Godspeed.
