@uberwaltz,
On the Vanilla Fudge lp (Sundazed mono)........(I just played it yesterday through the Sussurro).....the central imaging is readily improved, more open, the bass has more power, more air around the performance. Turns out both cartridges are sounding best on the same load setting. I'll have more to say later as I haven't listened to the Cadenza in around three years. I am happy and quite surprised to hear as much difference as I did so far.
