Vienna Mozart Grand or Beethoven Baby Grand


Anyone compared these two? I am trying my friends old Mozart (the pre-Grand model) and its really good but considering stepping up to the Beethoven Baby Grand. I have a Moon I-3RS amp, goes really well with the Mozarts.

Also the Hifi News Aug 08 review of the Beethoven Baby Grand suggests it could be a demanding amp load as the minimum impedance gets down to 1.5ohms (average is 4ohms). Does anyone know what this means? My amp, the Simaudio moon I-3RS is rated 200W at 2ohm - could the speakers damage the amp when the impedance gets low?
Thanks for your help in advance.

The damping factor for an amp is usually published as such in the specifications of an amplifier. If you can't find the info on the manufacturer's web site, please get in touch directly with your dealer or with the manufacturer itself.

I checked the amp specs - damping factor is >200. Would you say this is low or high? Is the higher the factor the cleaner the bass?
Acdvd, a damping factor of 200 is fairly reasonable. . . higher than that of my old Rowland Model 7 mono amp behemoths. You can expect a very slight flaring of the bass, which in fact you are likely to find rather pleasing to the ears. . . but should not encounter any obvious problems. Regardless, remember that speakers need to be broken in. . . a lot, lest they sound sterile. Guido
