Rolls RP220 is a dual channel tube preamp and unit has both XLR and 1/4" inputs and phantom power. Here is some additional information from a Sound on Sound review:
"These two Rolls units are extremely simple in concept, but where they differ from most of their rivals is that the audio signal path is entirely valve-based. Most valve mic preamps still use a solid-state input stage, but the MP220 mic preamp (badged under the name of the Rolls subsdiary Bellari) uses a transformer input followed by a two-stage valve (one dual triode) amplifier circuit. An instrument input and line setting allows the preamp to double as a DI box."
$175 each, plus shipping. I'll pay shipping in the continental US if you buy the pair. Located in Nashville.
