Does anyone know the differences between the highest end petrof pianos? I have been going back and forth between digital and acoustic and I have decided (I think) on an acoustic but I can't get a mini or grand due to space. Are the petrof's the "brand" to get for uprights? Money isn't an object but I don't want to spend 20K. I have hear and played the yamaha U1 but it is too bright for my taste and doesn't have any soul to the sound. Is there another brand that I should consider? I keep hearing that the highest end petrofs are absolutely awesome and can come almost as close to the sound of a baby grand

Welcome to the forum, billyg.

My understanding is that the innards of the 3 different Petrof models are the same. The difference is in the case. The 135 is an inch taller (and I would imagine a little heavier). At one time, Petrof experimented with a Ciresa spruce (Italy) soundboard, but I don't think they do that anymore (look on the back to see). The M1 has a traditional folding desk on the fallboard. The E1 has a non-folding desk ledge set at a higher level (more like the grand level).

I have the E1. I am very happy with it. I love the action. It allows me great freedom and I can bottom at ppp. The tone was also what I was listening for. Typically, Petrof installs Renner hammers on these models, though their literature indicates Abel hammers can also be installed. My Renners got a little too bright after one year and I just had some voicing done. I've fallen in love all over again.

For me, it was a hands down favorite of all under $10K uprights, but thats my tone bias. You have indicated a bias against overly bright. In the $10K or less range you should also try Walter,Bohemia and Kawai at least.

However, you seem to indicate that it would not be a problem to go over $10K. That puts you into some other company that you should try. For example, Sauter, Seiler, and Schimmel. If money is not much of an object, most uprights are in play. Don't go by what you hear people say, go by what you hear the pianos say.

Well, I don't know about awesome. That's up to you. But definitely very different from Yamaha and Kawai and definitely worth seeking out.

The 135 is really the 131 in a taller artsy cabinet. Internals are the same. Here are two links. The first is to the former distributor. Some of those pianos are still in the market and generally well-priced (discounts available).

The second link is to the new distributor. I haven't seen any of those myself. Compare the specs. There may be changes.

Do not forget to click the additional 'internal' links for each model within the link turandot mentioned.

For the 131: http://www.petrof.com/upright-piano-p-131-m1-description.html

For the 135: http://www.petrof.com/upright-piano-p-135-k1-description.html

After reading you'll notice the main difference is the genuine SUSTENOTO (middle) medal in the 135 (which Petrof translates as 'prolongement function provided by the middle pedal'): http://www.petrof.com/function_of_pedals_of_petrof_135_upright_piano.html

I don't follow.

Do you mean there are 131's with a real sostenuto pedal?

For the 131 Petrof says the middle pedal is a moderator pedal. For the the 135 it ha a sostenuto function, the moderator function being provided by an extra lever.

it looks that way, Schwammerl, at least from the 131 site you posted. i too have always been under the impression that the 131 does not have a real sostenuto pedal.

We are getting a Petrof 131M1 delivered today. It does not have a sontenuto pedal. The 135 has a sostenuto pedal and slow closing fallboard for 5K more. Both have full renner action.
