Hi All,

As promised some time ago, here are my impressions on the DP-603 now that I've had some time with it. I should note that I've had very little interaction with Piano Designer or other settings; I just turn it on and play...

The keybed is a HUGE improvement over the PHA4 Standard in the DP-30. Much improved dynamic range, and I don't get the occasional "missed note" when tapping the keys rather than fully depressing them. This is due to the sensors being triggered by the hammer in the PHA50 (so as long as the hammer has enough momentum to "hit the string", the note will sound regardless of how far the key itself traveled downward), vs sensors triggered by the key itself in the PHA4, which requires more follow through on the stroke, regardless of initial force.

The piano sounds, again better dynamic control since it's fully modeled. I'm not overly impressed with the DP-603's speakers, but it's nice for small spaces. Headphones sound much better. If you want good speakers + amp, go with the LX-17, etc...

To summarize, it hits the BIG TWO for me: feel and sound (with headphones). I find myself enjoying playing it and practicing for longer periods, which IMO is an indicator of good overall function.

I chose the DP-603 because it has the same keybed action and sound engine as the more luxurious LX-17 at a price I was comfortable spending sight unseen.

If you still want to run your monitors from a balanced signal:

. . . You need a "1:1" DI box (two of them, or one stereo box if you can find it).

Standard DI boxes have transformers that do an impedance transformation (as well as unbalanced-to-balanced). Roughly speaking, they change a line-level unbalanced signal to a _mic-level_ balanced signal.

I suspect the LSR308's will be considerably better than what's built into the DP603.

Thanks Charles...

Yes, I forgot to mention that part. I ended up getting a Radial PROD2 direct box, and all high-end cables for both sides, and the sound was amazing!

I say "was" because the monitors are currently not hooked up (which is probably why I forgot to mention them), But yes the PROD2 with an LSR308 pair is a great addition to the internal speakers! I highly recommend them.

I'm rearranging some things and hope to have them hooked up again soon.

Interesting review. I have also found the dynamic range on my FP-30 to be limited. But I assumed it was deliberate compression of the volume levels to accommodate the basic speakers on the FP-30. It did seem to be not as bad through Pianoteq; do you use Pianoteq, and does it feel better with the HP603?

I am contemplating a DP603, but if you were disappointed with the HP603 sound quality then it may not work out. Unfortunately for the space I have the LX-17 is too tall.

Do you still use Pianoteq, and why (instead of only playing the HP-603)?

Are you upgrading DP603 to HP603? I just preordered the DP603 since I thought the DP603 and the HP603 are pretty much the same except the Bluetooth connection (not the midi) that DP603 has, but not HP603. I'm wondering if my assumption is wrong.

If it's any help, the DP90e had a very good sound from it's own speakers. In a big showroom, too.

I actually haven't tried using the DP-603 with Pianoteq, as I'm pretty happy with it's built-in sounds. However I would certainly think that the improved dynamics would translate to a better Pianoteq experience as well.

Was my original post edited by the mods? I could have sworn I wrote "DP-603" in the subject as well as the review itself, but it now reads "HP-603". ????

While the two are similar as far as the brains and keybed, the cabinet designs are very different.

In any case, the DP-603 is what I own, and what my review is about!

I thought it was supposed to be DP-603, so I was confused too. :-)

Now your review makes sense! It was definitely titled HP-603 when I first read it.

So I should lower my expectations of the DP603 sound. But I'm starting to think it's unrealistic to expect onboard speakers on anything less than an LX17 or AvantGrand to sound as good as replaying a WAV file through a decent hifi. So maybe a DP603 + external speakers is the way to go after all?

Thank you for the clarification. I was like the DP603 just came out not too long ago and you already upgraded it to HP603. 😂

I wonder if the sound system on the DP603 (polished black) might sound better than the cheaper model? It is enormously more expensive. On previous models, you got a better keyboard too . . .

Thanks! I did that just now...

IMO yes. I'm quite happy with my setup.

As far as I can find out, the cabinet finish is the only difference between the polished and contenporary black i.e. same specs all around, including amp & speaker:
Two 12 cm (4-3/4 inches) speakers at 30W each.

I noticed when I played Pianoteq through the Kawai ES8 speakers that it sounded More dynamic and louder than the internal sounds.

...so it looks like the mods corrected my post to read "DP-603", thanks!
But they also changed the "FP-30" to "DP-30", which is inaccurate and I DID NOT ASK for.
***sigh*** pick your battles, i guess, lol...

Most pianos will use similarly sized speakers but without some "heft" of the cabinet and a larger volume of the speaker cavity the speakers will be only good for near field listening and will start to sound rapidly thin with the distance.
You can't escape it, if you want good sound inside the piano you are looking for a much heavier and larger and more costly DP.

Or a small PA system. It makes an enormous difference playing anywhere live.
