Hi Paolo, the Yamaha SE 132 was a *NEW* piano, still cellophane-wrapped to be clear, at an official Yamaha dealer (who had the entire series). The seller explained to me that the SE series is the top of the line for Yamaha uprights, produced specifically to satisfy European tastes (hence the European sound that I liked), and the E stands for "Europe". It is made in a semi-artisanal way and goes through the same technicians who care for the CFX grand series, to be clear. The seller, who seemed very competent to me, spoke of a part made by Bösendorfer (not the strings, but an important steel part that Yamaha buys specifically from Bösendorfer, I don't remember the terminology), Renner hammers (I got confused before, not Abel, but Renner) and a soundboard made in Europe. The piano leaves the factory like this, no replacements, no interventions. The list price is 14-something thousand + VAT, the shopkeeper would give it to me for 13,000 discounted.
In the same shop, there were also two used Schimmels, but in my opinion, when talking about used instruments, the wear and tear of the various parts and how much the instrument has been used matters immensely. Among all the German used ones, the one that sounded best was the Krauss. The two Schimmels sounded quite "used", even if with a nice timbre; the Krauss seemed as if it had never been played. In fact, in the same shop, there were two identical Krausses, but one was a bit clattery and the other perfect; evidently, they had stepped on the first one a bit more. The action of the used Germans was less precise than the recent Yamaha action, there's no way around it. So I think that, at least with used instruments, rather than the brand, you need to try the individual specimen and see if it satisfies you. Am I right?
The U3 will have a good quality/price ratio, but it still costs 8,000 euros, which is not 1,000 euros. And I can't bring myself to spend 8,000 euros for a sound that doesn't make me fall in love. I am talking about a clean sound but far too neutral, poor in harmonics. And I say this again. By the way, I had the good fortune of trying new and refurbished Yamahas side by side and the difference is certainly felt, even if they were refurbished in Japan by the parent company with a certificate. I will never buy a refurbished one.
The only thing that scares me about German used pianos is age. Don't they say that an old piano is still an old piano, that over time pianos get worse, that the soundboard loses its tension, etc.? I mean, I am 30 years old and I want a piano to play on for quite a while, not a nice old piano that abandons me in 5 years... what do you think?
