Preamp better than Cortese?

It seems Supratek offers enormous value for $$.

So far from above posts it seems Audio Note (ok 50% costlier) and H-CATs (cheaper) are the preamps compared to and MIGHT be better than Cortese (ok it is subjective). Any other pres like Ayre K1x or transformer passives like Silver Rock/Bent TX102s/Dog which might be comparable to Cortese in performance?
