New Sony HAP-Z1ES Firmware Out Today

Do you need to send your player to Sony in order to rollback to the previous version? If you don't, how do we rollback to the previous version? thanks 

Downloaded and updated to the new software today. Not using a USB DAC, just balanced out to a headphone amp (Woo WA22) and using the headphone in balanced mode.

I would swear the HAPZ1ES sounds smoother, more detailed, and a tad warmer than before, and less dry or clinical. Not having a chance to A/B. I did listen to a few cuts, then updated, then listened those cuts again. Much prefer the new version.

If they don't end up supporting Tidal, hopefully Spotify will launch and Sony HAP will support Hi Rez. I'd really like to simply down to one device for all digital music needs.

@davehg Interesting to hear about the perceived improvement after the latest firmware.  I recently updated firmware as well, although I did not A/B the sound quality, presuming there would be only functionality updates, not sound updates.  I will say that the HAP-Z1ES seems to improve over time (burn in), although that may be psychological, right?

Anyone know for sure whether Sony's going to keep this model up to date?  Like most users, I'm eager to try higher-res streaming (preferring Spotify) if and when it becomes available.

All,

A white horizontal line appeared in the display of my HAP-Z1ES about two months ago.  I do not know if the line is relevant to, or connected with, the cessation of function of my HAP when the internal drive becomes full or nearly full (see my previous post, above).

After perusing Sony's online information regarding the HAP, I contacted Sony via its support phone number (1 (877) 643-1216. To my surprise, a person answered the phone when I called; the person understood what I was talking about; the person did not ask me endless irrelevant questions; and the person genuinely attempted to answer my questions. Sony is sending me a repair ticket and will repair my HAP at no cost. The gentleman who answered the phone said the repair would take 5-7 business days.

Has anyone here been experimenting with externals DACs connected to the HAP-Z1ES USB port?  Is the signal that comes from the HAP USB port to the external DAC a PCM signal or a DSD signal?  Can we choose, or designate, the type of signal sent from the USB port to the external DAC?  Can we configure the HAP-Z1ES to send a PCM signal through its USB port?

One reason I ask is that The Absolute Sound, in its May/June 2017 issue (which has just come out, at least online), has an article by Robert Harley regarding the "Schiit Audio Yggdrasil DAC".  Harley states this DAC, which will accept a PCM signal but not DSD, is one of the three greatest DACs, at any price, he's ever heard (the other DACs cost $19,500 and $35,000, respectively).  He raved about it.  Given the reasonable price ($2300) of the Schiit DAC, it would be very nice and very handy if the HAP-Z1ES could be configured to emit a PCM signal from its USB port so the Schiit could accept the signal and do its magic to it.

I have an Auralic Vega DAC connected to my Sony HAP Z1's USB port and there is a definite improvement in the sound. I’m outputting 44.1kb, flac, DSD 64 and DSD 128. Wonderful!
