new to tubes

i have never had any tube equipment and am thinking about trying it out. i am learning slowly about it and thinking about taking a leap with a lower priced piece. i currently have a Cambridge Audio 840v2 integrated amp and a pair of Fritz Grove monitors. my only source is a Squeezebox Touch. i already plan to get an Eastern Electric Dac. my only concern is how much power is enough to drive the groves as they are only 86db efficient. my room is only 13'x 11' treated,and i dont listen past 92 db. i'm thinking on the lines of a Jolida 502b to start. trying to stay under $1000 used. any thoughts?

You could pick up an Onix Sp3 for about $500, that should give you a good low cost intro to tubes. If you don't like it or want more power you can resell it for about the same price you paid for it.

What did the manufacturer recommend for using tubes for amplification?

If the amplifier has an output impedance that is low enough, you can have variations in impedance that will not result in tonality issues with most tube amps, as long as the variations are not extreme. For example, a 4 ohm dip at a crossover frequency can be considered benign.

A lot has to do with the intention of the designer of the speaker- if the speaker is designed to be friendly to tubes, that is usually more important than the actual impedances.

What did he say was the minimum impedance of the Grove speakers?
