Rowland 102 specs are at:
http://jeffrowland.com/M102.htm
The 102 has an input impedance of 40KOhms, this is high enough to make it compatible with most preamplifiers. . . what is the output impedance of your pre?
The damping factor of 102 appears to be 1000, which should enable it to drive speakers with fluctuating impedance curves without issues. On the other hand, I do not know what the power handling characteristics of your speakers may be. . . 102 can generate 11 Amps and 100W into 8Ohms and 200W into 4Ohms. Guido
