I'm in process of buying new amp for live applications. I'm thinking about trying something unusual and since almost all amps have some kind of colour, i narrowed my choice to some kind of NEVE preamp copy and power amp. Have you ever seen or used something like that live? Even Talkbass doesn't offer much info on combo like this. Warm audio preamps with EQ are priced just right for me, but i'm not sure if studio equipement is really road worthy. Second choice would be Demeter Preamp HBP_1.
