Sony HAPZ1 For prospective buyers and owners


I have been encouraged to share my experiences with the new Sony HAPZ1ES. I hope a few who may be considering purchase of this unit will find this useful. I expect those not interested in purchasing this unit will want to tune this thread out. There is going to be some detail here. I will provide a summary statement with significant conclusions at the beginning of each days record for those not interested in the details.

It would probably be good to start with a few words to provide a frame of reference. I’m not a computer geek. I’m a reasonably bright guy, but a computer to me is just a tool. It’s a hammer that enables driving a nail, that’s it. I learn what I need to know to do what I want to do and that is all.

My interest in the new Sony is that I expected it would facilitate a long standing goal of assembling a computer based system. Further, it accommodates Hi Rez files, and does on the fly conversion of PCM to DSD. It also offers streaming audio, allowing convenient playback of internet radio. It has a 1 TB hard drive, so there is a lot of room for my substantial music collection.

For me, the deciding factor in purchase of this piece was Dan Wright’s enthusiasm for the stock unit and rapid development of a ModWright upgrade package which he says takes the HAPZ1 to reference levels.

Day 1- Initial set up easy, sound quality indeterminate.

I unpacked the unit and gave it about 4 hours to return to room temperature before turning it on. First order of business was to establish the wireless connection with my home network. This was straightforward and took less than 30 minutes to complete. The unit comes with a small amount of software on the hard drive, so this allowed me to begin playing without having to begin download of my existing music library to the internal hard drive. I played through the free music twice, just to give the unit a little burn in time. The free music selection was not my cup of tea, so I could not draw any real conclusions about sound quality.

Day 2- Some frustration with getting set up for download. Interactions with Sony Tech support a mixed bag. Concerned about Sony’s ability to help Mac users. Sound quality with a casual listen promising with under 10 hours burn in.

I spent about a half an hour transferring music from CD to my iMac. Once this was complete, I went to the Sony website and downloaded the free HAP music transfer software to my iMac. Again this was completely straightforward. Upon opening the program, I ran into the first snag. The box that popped up asked me to select the device to which I wanted to connect. There were no devices to select. I began a dialogue with Sony using the chat room accessible from their website. The person who attempted to help me was completely clueless. She referred me to documents which did not address my problem, referred me to documents addressing connection problems with windows machines, and finally, after wasting about 20 minutes of my time admitted she couldn’t help me. She gave me the Sony tech support number.
I called the number (1-800-222-7669) and went through about 3 people before I got to the correct department. This wasn’t as frustrating as it sounds- It just took a few seconds to get to the Sony home audio ES support line. There was about a 10 minute wait until someone took my call. The guy I talked to was pretty sharp. However, his ability to help was hampered by the fact that “ we don’t have a Mac here.” Well, I would suggest that Sony get one!
While we were talking, he indicated that sometimes it takes a few minutes for the music transfer software to find the device. We worked on the problem for a few minutes, and while he was looking something up, I figured out what was wrong. My iMac bluetooth was looking for the wrong network. Once I selected the correct network, the music transfer software found the HAPZ1 immediately. I selected the device, and he advised checking the content settings. A new box shows file extensions that you can select or deselect to be transferred. While flac, wav, mp3, and 12 others appeared as options, ALAC (Apple lossless) did not appear. However, the support guy did a quick Google and found that m4a is the correct file type for ALAC, and that is one of the types listed so I was OK there. I also added /users/my user name/Music/iTunes as a folder to be watched, which probably wasn’t necessary.
Next, I went to the transfer settings. I turned the auto transfer feature off, and selected internal HDD as the destination since I don’t have an external hard drive yet. I activated the manual transfer, which I was doing wirelessly to see how long it would take to transfer the 200 files (tracks). I walked away for a few minutes and when I came back, I found that the transfer had stopped incomplete. I started the manual transfer again and walked away again. When I returned, the same thing had occurred. This may be due to an auto standby feature which apparently shuts the HAPZ1 down after a few minutes with no activity. I turned this off, but I had enough music transferred to give a more serious listen to the unit. I listened to part 1 of the Dunedin Consort recording of the Bach Johannes Passion. This is a wonderful performance, with recording quality that I have found to be somewhat spotty. It is wonderful in the aria and recicitives, but rough in the Chorals. Played back through the HAPZ1, this was pretty close to what I remembered playing through my ModWright Sony 5400. Next I played the Purcell Quartet recordings of Bach’s Mass in G minor BWV235. This is a standard redbook CD, so I was interested to see what the conversion to DSD 2 would sound like. In a word, playback of this music was just absolutely lovely! I suspect this unit, stock, may give my ModWright Sony 5400 a run for its money, but a serious A/B is still several days down the road.

Brownsfan, I checked the Modwright homepage and there is no mention of a new DAC. Where can I get info regarding the release of their DAC that you mentioned?

Mitch, Macs using iTunes don't rip to flac, although they can if one uses other software. Downloads in flac are no problem. I have a few albums transferred in wav, but the vast majority are in aiff, which is similar to wav in that it is not compressed. If you go back and look at the earlier posts, you will be reminded that I found with a sampling of albums, wav sounded subtly better than ALAC. Based on this finding, coupled with a few trials in which I could not distinguish between aiff and wav, I decided to commit to aiff, which usually transfers without corruption as opposed to wav, which was a nightmare of corruption. I did work out a laborious protocol for using wav and maintaining it in uncorrupted form once it is transferred, but since I can't discern between wav and aiff, I'm not motivated to use it at this point.

With almost 800 albums transferred, I still have slightly more than one half of the internal hard drive space free. Clearly, I could transfer the remainder of my library without using an external drive. An additional comment that I would make is that with most albums, I could not discern a difference between wav, ALAC, and aiff. However, since HD space is not limiting, I just went with transferring uncompressed files rather than sorting out which ones would benefit.

Once the bulk of the library is transferred, I want to identify my first and second choices for classical works, then either transfer the 3rd, 4th, and sometimes 5th choices of a particular work to an external drive as well as some works that very rarely get a listen (Sorry Elliot Carter, but you have had your chance-time to show you the way to the external drive.) That way, I should always have room for additional acquisitions to the library on the internal drive.

Another thing I am noticing is that using the album view for selecting music is becoming somewhat cumbersome. Between, Bach, Bartok, Barber, Beethoven, Bernstein, Brahms, and Britten, it takes a while just to swipe through the B's, and I have nowhere near all of my Bach and Beethoven loaded yet. However, this is nowhere near the problem of trying to find or even remember that I have certain albums in hard media (still can't find that Abaddo Mahler 1). I am going to go through the titles and be more specific on genre, which will help me get to a given work more quickly. For instance, there is no reason why I can't define genre more narrowly, for instance, using Lieder, rather than classical, as the genre for my beloved Schubert Lieder, which will allow me to quickly access the music without swiping all the way to the S's in the album view. I am avoiding use of the favorites flag. Too tempting to have my library effectively reduced to 100 titles! Also, I am finding that some recordings I avoided because of bad sound demand a reassessment. But these are subtleties that can wait for an opportune time.
I will bring in a good pair of NOS 6922s to compare with the 6GC7s. I'm open to suggestions.
In my current system, 60's Siemens e88cc is my favorite and then Telefunken e88cc. Siemens is probably tough to find but checkout Upscale Audio for NOS Tele. Vinnie from RedWine Audio is rolling them in his HAPZ1 mod. These tubes are very linear and neutral.

Brownsfan, any news to report on the further break-in?

Have you moved yet?

Mitch, my updates on burn in were "complicated" by purchase of new amplifiers. This rendered any continuation of the burn in progress impossible, since there was a quantum jump in performance of the system with the new amps. The amps are new so they are also burning in. I wanted to trade in my old equipment on the new amps, so I had to do this before moving out of the Coincident dealers sales territory. I do wish I could have gotten another 100 hours on the HAPZ1 to complete the comparison before buying the new amps, but because of the impending move I needed to act.

What I will be able to do, as soon as time permits, is do another careful A/b of the HAPZ1 vs the Modwright Sony 5400 player. Since that was the time zero reference point, this will provide a very good end point analysis of the fully burned in Modwright HAPZ1.

I am in the midst of purchase of the new house and won't close until late October. Our house is not yet on the market, and essentially all of my time is consumed with keeping things moving with the 2 houses. I will certainly be glad when this move is over. It is never painless to move, but this is more than I anticipated.

I can say this on the HAPZ1. I hardly ever listen to the MW 5400 anymore. It is a very good source.
