The crunch channel of my old TSL100 held up surprisingly well alongside a late ‘70s 2203, although neither was cranked at the time. I preferred the tone of the 2203 and am certain my preference would grow with increasing volume. At a residential friendly volume, however, I can easily see the TSL sounding better. I don’t really care for the sound of the cold clipping stage by itself. I can’t speak for the TSL60.
