Exploring Preamp options for the Pass XA25

I have both HPA1 and LTA MZ3 as preamp to XA25. They are both great choices and there are reviews describing the pair online.

What speakers are you using with that combo?

@t_ramey 

currently. OHM Walsh 5000's...

Also have had DynAudio Contour 60's, Klipsch Epic CF-4's hooked up for long test runs.  For kicks I had some old OHM Pro-200's hooked up (sounded suprisingly good).

At a friends house I've heard Salk SS12's hooked up to the XP12 and X 150.8

dep 14.. the first thing is a remote control. I thought when I bought the Audio Research LS3 that I could do without a volume control.. nah. Presently I have Zu Omen.
