I do plan on using them on a pair of Utopia's as I've read that Utopia's pair well with tube amps, of course I'd be deciding later on if that's actually true once I get my Utopia towards the end of this year or start of next year. Thanks for the info about the pairing with the Flows, will keep that in mind! Yeah, big bummer that there doesn't seem to be a dealer here anymore. I think there used to be one but I asked them recently if they still sell Woo Audio products and they seemed to have dropped it from their store at some point. Might ask around locally if anyone has any WA amps.
