How to reproduce sound of piano

Again, I would advise against getting a sub first. Have everything else set up to your satisfaction first. After that, yes I would say that a sub is essential. ( or even one for each channel) A sub is not only about getting the bottom octaves more right, but if set up correctly, will give you a lot of ambient cues about the recording venture and you can fine tune soundstage and transparency. Also finding the right sub to sound right in your room will depend on wether you decide on SS or tube amplification. Many subs of today have digital amplification, which according to my experience does not homogenize properly with the rest of the system, if you use tubes. I'd advise not to rush it and later, once you are happy with your system, try out a few brands if you can until you are satisfied.

I'd try playing with current speaker location 1st as SoGood suggested because that's easiest and no cost.

Try to listen with them out away from rear and side walls for better imaging and in order to allow those beautiful piano key strikes some breathing room with which to reverberate .

The next step if things are looking up at that point (good chance) might be adding the sub(s) to fill in the low end.

Dave,
then you should know how difficult it is to get it right. Don't forget Plaser is new to this and as you should know with your experience, it is the easiest thing in the world to ruin your entire system with subs which are not blended right into the rest. Having had a look at your system, which I find impressive, I don't think it is built around the idea of getting classical piano right foremost and all. Plaser however seems to aim at that and I had that in mind, when I issued my warning.
Sorry, should I have stepped on your toes, in my over 50 years experience (; I have learned that many ways lead to Rome but it mostly brings mediocre results if you rush on the way.

My suggestions relate to the room you are in now, and the components you are using now...and not the room you are going to build (which I know nothing about).

I also don't know when you plan on moving to your new home. The intent is to get you some passable results in the nearer term (I am also assuming you like your speakers for the most part, I think you said you did?).

What you probably don't like (regarding piano recordings) is the missing heft, of the lower notes, that the piano is producing, but your speakers are not reproducing (because they can't).

Like many audiophiles I have several speaker systems, two fullrange systems, and three less than fullrange speaker systems.

I like them all, and I also play a lot of piano music (we probably all do). That said, the piano sounds more real, and much better overall, on the two fullrange systems. The answer for that is simple...the fullrange systems paint a better picture, or at least...a better copy of the original picture, than the smaller speakers are able. No rocket science involved.

I suggested 30hz, and small subwoofers based on your room...and what looks to be, limited placement options in that room.

I would not buy any components for your new home, until well after the move in. because you will need lots of time to think things out, unless you like doing everything twice (-:

When I retired around 8 years ago, I built a fairly large dedicated room (my son helped me), and it took us around 6 months... (4 months of thought, and two months of work).

I can tell you that it was well worth it.

Good luck,

Dave

No, you didn't step on my toes at all, no problem (we are all trying to help, and usually with somewhat limited info)...I guess I just don't find subwoofers, that complicated an animal to tame.
