Pass amps can they handle a highly reactive speaker load?


Ok so I've learned a lesson after being in this hobble for almost 40 yrs no matter how great a tube amp is it will only be as great as it can be on a speaker that doesn't dance around with its impedance load electrically. How well does pass labs amps handle this situation? Martin Logan's are a very reactive load would pass handle the job.

It depends on the Pass Labs model. Some of the Pass Labs Aleph models were unsuitable for such a load. Other Aleph models might be good. Most of the X series should be good.  I too am a fan of a lot of Nelson Pass's work, and it's a become a tad controversial to criticize his work around here lately, but I've found some of Stereophile's bench testing measurements a bit concerning. Despite general assumptions about the technical capabilities of these amps to the contrary; it appears as though more than a couple of Pass Labs products have struggled on the test bench when driven into some lower impedances. Could be a good or even excellent choice, but tread with some caution.
