Jolida 102b Speaker Recommendations

I recently acquired a Jolida 102b tube (EL84) integrated amp. Factory specs say it is 20 watts per channel, some say a bit less maybe 15 wpc. Looking to hear from anyone who has owned/heard this amp with speakers that were a good match for this amp. I have read that the Klipsch Heresy speakers are a good match. I would prefer to go with a vintage speaker if possible, but will consider anything used under about $500/pr. I am somewhat handy with speakers and can refoam drivers and upgrade crossovers. Thanks.
