Krell Evolution or Pass XA.5 series


Anyone compare the Krell Evolution to the Pass XA series (all prices being equal) on medium efficiency speakers (89-93db). Curious if you did compare them what was the circumstances and system. I did read in one magazine the XA has a warmer midbass, while the Krell Evolution has better bass. I just want a little more information than that.

Would you define "better bass"?
It was a short blurb. I guess stronger bass would be more correct. I am curious about other peoples experiences. As I have only heard them at shows.
Stronger meaning louder bass relative to the midrange and treble? If not louder, then define stronger.

In other words, if a Pass Labs amp produces well-defined, controlled bass in balance with the midrange and treble (which is what I hear from mine), then if the Krell produces bass that's louder than the midrange and treble, you would consider this stronger (and better)?

Just trying to get a handle on what type of bass production you want.
