Just a 2010 Steinway Model A (sadly).
We went to Steinway Hall (London) and they set out 6 instruments for us. The one we chose was the clear winner in terms of its most beautiful resonant sound.
In our home (with wooden floor boards and a nice cavity underneath), it sounds beautiful - really bright when played FFF and a gorgeous sound when played ppp.
The only downside is that it has taken about 5 years for the tuning to settle (it went all over the place - even when the tuner was tuning it).
I've already reported a general issue with all the Synchron pianos (or it's a plugin issue) - the key noise control doesn't work. It has been confirmed that this is a bug. Looking forwards to this being fixed.
