What amp will it be used with? The TAD 125s? With ARC, I'd expect those to provide a most resolving sound similar to the best tube gear I have heard, which tends to resemble SS more.
VTl and DeHavilland made my short list when looking probably can't go wron with either of those as well. Probably more of a personal taste thing. My gut says those will sound more "tubey" than the ARC based on what I have read, but have never actually heard these.
