I had a pretty good experience with the Yamaha CFX Synchron Piano: the quality of the sound, but even more the nice feeling of playing it (with a 88 weighted keys piano controller of course) was stimulating me to buy something more, and I decided to buy the Steinway D as well.
The first feeling with the Steinway, as other reported before the update, was of love and hate, wonder and blame.
The first impression was really weird... perfect recording, amazing sound, but loudly metallic and out of control, compared to the perfect balance of the Yamaha, but I had a pretty emotional and nice flashback... it had something hyper-realistic, weared, like an old consumed instrument, and I found my self for a moment back in the 90's playing the old Steinway of my Conservatorio, in the empty auditorium hall... 😃
After the last update, the instrument is back to a more equilibrated and fine sound, still bright but no longer excessive. It has lost a bit of caracter, but at least it is now in line with the Yamaha, and you may play them in sequence without a big change or excessive need of adaptation.
Despite the improvement, and despite the fact it is a pretty nice piano, still I can't join the number of Steinway's fans and Yamaha detractors. In real life I also always loved the Steinway sound more than Yamaha, but with the Synchron Pianos i have to say the opposite:
there is something so perfect and well balanced in the Yamaha CFX Synchron Piano, that still surprises and captures me every time I play it... deep bass, vibrating but never metallic... sweet treble, sharp but never nasty... superb uniformity across the whole range. So finally I loved the Steinway D last update, but Yamaha CFX is my favorite one. Does anybody agree?
