A tad spendy , however I would recommend sourcing a matched ( if possible ) quad of pre 1980’s production Reflector Corps 6h30-DR ‘s
they will take your VSi75 up a notch and should blend in very well with KT150’s
Beware ... there are many unscrupulous individuals on line passing off new production as NOS DR’s ... this should help
