The major difference seems to be that the Psvane is far more extended at the frequency extremes,but at the same time has a far more richer harmonic presentation. Much like the qualities of NOS 845′s  In comparison to the others, the 845T, right out of the box, seems brighter. After about 10 hours I began to notice a difference. Compared to the 845B, they seem far more transparent but at the same time much cleaner. Bass tones and pitch definition are improved. String tone seems to be...
