The most striking thing we learned, is that Laszlo, the oldest, was superior. Apparently modern handmade cellos can gain a lot of tonal maturity with a couple of years of regular play.
The cello on the right (as yet unnamed) cannot be faulted for tone either. It's very impressive and very different from Laszlo, and it's begging for a couple of years of steady play from someone more skilled than myself.
The white cello on the left has a big tone and a dark powerful C string. Which allows me to say that it shows great promise. However, experience suggests that the process of varnishing, matching strings to the instrument, changing the soundpost and installing a custom bridge and fittings will change the the tone. Not to mention the tonal change that will likely result from many hours of playing. Having said that, I'm pretty excited about the prospects.
