Ortofon carts are too hot for my phono preamp?


When I need hardware advice, I always come to Audiogon for the true experts.  Thanks in advance and happy Easter!

So after much trial and error, I THINK I have deduced that my Ortofon 2M Bronze and 2M Black cartridges are too hot for my Avid Pulsus phono preamp.  Some softer recordings are fine, but I think I am hearing some distortion with loud transients and even sometimes on relatively loud vocals.

I have a Pro-ject tube phono preamp I swap in and I don’ t hear that distortion. I never hear that distortion with other sources. 

Given my investment in 3 Ortofon 2M carts (1 Bronze, 1 Black, 1 Black SE) and the Pulsus, is there anything I can do to step down that signal from the carts without doing any damage to the sound?  

Any other thoughts?

(BTW the 2 turntables I am using are a Rega P3/24 and an older Rotel.  Meridian preamp has variable gain settings on inputs and I can hear the distortion at any setting.)

Lack of dynamic range/headroom on some phono stages certainly exists. Sell the Avid and use the Pro-Ject. The Ortofon mm's have typical output levels. 

Another cause of distortion is cartridge mistracking on heavily modulated passages. You can buy a Shure Test Record and test your cartridges to find out how they will perform.
