For what I am concerned, my AT440MLa (universally considered "toppy") into your Reflex M is not bright at all, just perfect (and I usually HATE a bright sound). So, good job! But that's just my ears!

Again, same here for me with the Bronze and the Reflex. Just perfect. On the contrary, it was with the Black that I found highs (cymbals, etc) slightly hot and "ringing". |

RE: the 440, there is frequency peaking around 10Khz or so, and it's pretty prominent. This is at 47K ohm loading with 100pf at the phono stage + common cabling (add another 100pf or so). That's what makes it sound bright and it's very easy to measure that with a test LP that has a frequency sweep. Load the 47K down to 39K with resistive loading plugs and it will tame that peak as I showed in my graph upthread. It's a quirk of the cartridge. Can't blame a "faithful" RIAA phono stage for not fixing a cartridge problem. It's like taking a pair of speakers that have very prominent peaking, then blaming a "flat" amplifier for not taming the peaking. Here is graph of the 440mla FR as done by Miller Audio Research. The 440mlb will have the same type of peaking you see in the graph as these carts are nearly identical. The newer 540ml which replaced the 440 models tames this peaking somewhat.
