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 amp I believe was the reference 200.2 S2; not sure about the preamp

Miner, the B&K reference 200.2 S2 apparently has a stated damping factor of 450, which should be quite good for driving the Mozarts without bloat. I honestly have no idea what the problem may have been, except perhaps for equipment not well broken in.

i have heard both the beethoven baby grands and the mozart grands. (i bot the beethovens). they r totally diff speakers sound wise and technically. the mozart is a 2.5 design w/diff crossover. i think the baby grands sound much better. however, the baby grands are very finicky about room placement, and if not set up correctly, u will get bass boom. yes, the impedance can drop pretty low on the beethovens, so b careful. i m not sure about your i-3. i have the i-5 and i really shud upgrade to a more powerful amp.

Good point Dlee. The VA Baby Grands have a rear-firing, which need to engage the rear wall, BUT moving them just a fraction of an inch can produce a bass node or hump that'll spoil the overall balance and the mids. Fortunately, only a little patience is needed to get it right. Better yet, in the US, if you buy from a Sumiko dealer they'll set it up for you using their amazing Master Set method and you'll hear exactly how good things can get.

Do you mean the closer you are to the wall the less bass node/hump you will get?

How far should they be from the rear wall?

Thanks
