what speakers are a good match for luxman lv-105

i listen to mostly latin jazz (alot of percussion) with real instruments piano, sax, trumpet, flute
Focal, Spendor. When pushed, this amp tends to be a bit bright from its SS amplification. If you've not changed out the tube, an upgrade will really open up things and give less edge in the midrange. A better tube will also tighten up and deepen the bass. Good luck.
Do you know which tubes sound best?
