I'm a little late to the party, but here are some responses to your comments/queries raised so far:
Is the es520 supposed to be a replacement for the es110 (seeing as the 110 has been on back order for months on dealer websites)? If so the price jump is ridiculous.
The ES520 is not a replacement for the ES110, but a new mid-range model that is positioned between the ES110 and ES920.
The one think putting me off is the saving of the inbuilt sequencer is that it saved it on to USB with the KSO type!! What is the point of that. Why not the midi file format which then can be used to put into sibelius or other programs.
I'm trying to clarify whether or not saving to SMF is possible, and the extent to which KSO differs from SMF.
with the exception of potential keyboard issues being fixed, which is what they said about ca99, but it seems to be not have made a difference...
I'm not sure which posts you're referring to, however to my knowledge, all of the criticisms of the GFII action were addressed by GFIII. However, that's not terribly relevant to this particular thread.
Also is there any demos of the 520 i have listened to the 920 ones.
ES520 audio demos can be found on the ES520 product page of the Kawai Global site, here
. The ES520 shares the same PHI sound engine with the CA49, so many of these stock MIDI-based demos will sound largely the same, although the recording process itself was a little different (ES520 demos captured from Line Out, CA49 demos captured from headphone output).
Does the es920 have a built in audio interface?
No, however it does allow WAV and MP3 audio files to be recorded to a USB memory device.
Is the RHIII action noisy? Has this aspect of the action been changed.
I'm not aware of any changes to the RHIII action cushioning for the ES920. It's not perfectly silent, but I don't find it overly noisy. Some players are more sensitive to these things than others, therefore it's probably best to play the instrument in person and check for yourself.
I read in a Piano Dreamer review that the 520 action is a little heavier than the 110 action. And the 520 is 6 pounds heavier to carry. Those two differences turn me of the 520.
As with Mickey_ above, I would recommend playing the instrument in person, rather than relying too much on online reviews. The ES520 is 2.5 kilos heavier than the ES110 due to the larger case and more powerful speaker system, among other things.
IMHO there are no incredible benefits in upgrading from an ES110 to an ES520.
This is a strange comment. Compared to the ES110, the ES520 offers: a superior keyboard action, superior piano sounds, superior non-piano sounds, a larger number of sounds, more powerful amp/speaker system, larger (more intuitive) control panel, OLED display, Bluetooth Audio, Line In, USB to Host/USB to Device connectivity, GFP-3 pedal support, and PianoRemote app support.
rintincop's needs are quite specific. He's obviously a big fan of the ES110's RHC keyboard action, enjoys the Kawai EX-based piano sounds, and requires the most portable instrument possible. For him, the additional 2.5kg in weight, and cost of part-exchanging his used ES110 for a brand-new ES520 may not be justified, however for other users, the ES520 would represent a significant upgrade over the ES110.
In preparing to write this post, I re-read the entire thread again, and noticed quite a lot of misinformed conjecture in your numerous posts. I believe you mean well, and wish to contribute useful information to this forum, however a considerable amount of what you've written in thread is incorrect and misleading.
Here are a few other general comments regarding other topics raised in this thread:
- Regarding price: Please note that the ES8 was announced 5 years ago, and its price has gradually fallen over time. The ES920 and ES520 have just been announced, are brand new, and in extremely high demand. I don't believe it's logical to make direct comparisons between the price of a product that's been on the market for 5 years, and one that was announced just a couple of weeks ago.
- Regarding technology: Please also note that just because the sound engine used by an instrument (e.g. HI-XL) has "not changed", it doesn't necessarily mean that the hardware inside the product is the same. For example, the ES920's CPU board is based on the CA59, which is completely different to that of the ES8. Comparing specification tables alone does not begin to tell the full story.
- Regarding "disabled features": The ES520 hardware is based on the CA49. That instrument does not support MP3/WAV audio playback, therefore this feature is not possible on the ES520. Suggesting that a feature has been purposely removed or disabled in the firmware simply to differentiate products is completely inaccurate and misleading.
- Regarding no "Pianist mode" on ES920: As noted above, the ES920's CPU board is based on the CA59, which also does not include "Pianist" mode. Unfortunately, the hardware required to run the "SK-EX Rendering" sound engine does not align with the target pricing of these instruments.
That's all for now. I hope this answers some (most?) of your queries. Please let me know if you have any further questions.
