It doesn't look like anyone has had that particular experience. Personally, I have no experience with Jeff Rowland products, except that I've seen them look good at various audio shows. I had my Aerius for over 15 years and know that they respond well to tube amps of at least 100wpc. They can use plenty of power to sound good, so if using a transistor amp, make sure it is has a beefy power supply and plenty of watts. We also have a thread about what types of amps to use for Martin Logan speakers, as this is one of the most often asked questions.
