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.

Uomoragno, you need to visit some of the download sites with classical music downloads when it comes to music for the HAP-Z1.

Some interesting choices there, including the first ever DSD releases by Cobra Records on NativeDSD.Com.

Apparently those 10 albums were recorded on the Sony Sonoma DSD Workstation years ago but only available as Stereo CD discs until now when we get Multichannel and Stereo DSD via downloads.
One more installment of the HAPZ1/MW5400 comparison.
Shostakovich, Symphony 13, "Babi Yar" Kitajenko, Gurzennich Orchester Koln. SACD Capriccio. This proved to be an outstanding choice for the comparison. The ALAC file through the HAPZ1 exhibited superior articulation of the Russian. (Not that I could do anything with this, since I don't understand a word of Russian). I also noticed better reproduction of the upper harmonics in the brass. The tuba had more bite. In fact, all of the brass had more of that wonderful brassy bite that one hears live in a hall with good acoustics. This more faithful reproduction of upper harmonics was also evident in the low string opening of the 3rd movement. There were a few instances where the MW5400 shone. This was mostly in reproduction of solo violin or massed violins. Lovely, silky smooth. But really, I thought the HAPZ1 bettered the MW5400 by a fair margin on this music.

This will be interesting to compare with the Modwright HAPZ1. It can only get better one would hope.
Lowrider, exactly. While I am not done with my comparison yet, I think it is safe to say the stock HAPZ1 is very good. Having detailed notes on particular pieces of music and having the MW Sony to use as the control for a comparison of the MW HAPZ1 should provide a very good measure of the order of magnitude of the improvement provided by the modification.

I am on the waiting list for the modification. I will ship my HAPZ1 out on May 15th, with the mod scheduled for after the Munich show. By then Dan will have had time to evaluate the Bybee rails.
