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.

Another week, I'm now up to about 750 albums on the hard drive. There have been a couple more very pleasant surprises this week. As I indicated in the last update, time to begin to work through Haydn and Mozart. Working through the Haydn string quartets, I was pretty much amazed by the transfers of the old Op. 76, 77, and 103 Takacs Quartet recordings on Decca. In particular, the improvement of the Op. 76 playback vs CD player was stunning. These are old recordings that I have had for a long time. Through my ModWright Sony 5400, the stock 5400, the Cambridge 840, and my old Denon 1640, these quartets were just about unlistenable. They sounded as if they had been recorded in an enormous cave, using a single microphone set back 100 meters from the players. Simply awful. Through the Modwright HAPZ1, these wonderful performances sounded lovely. Perhaps just a wee bit more hall ambience than I might like, but for the first time, these wonderful performances will get some serious playing time in my house. I can't explain what sounds like a complete change in venue and microphone set up. But the difference is profound.

The Op 64 quartets, this time by Quartor Mosaiques, in like fashion I found to be problematic in sound quality with cd playback. This time, there was something in the playback inducing listener fatigue, so that I just didn't enjoy these recordings. Much better through the HAPZ1. Not sure the performances are my cup of tea, but at least now I will give them enough time to draw a yea or nay conclusion.

Since I am spending so much time trying to get ready to move, I'm not getting the burn in hours or serious listening time I'd like to get. It is a slow process under these conditions. Can't be helped.
Brownsfan, excellent USEFUL info.

It's interesting Dan is gravitating to Lundahl transformer coupled and I guess in this case, no caps are better than best caps?

There's a new DAC flavor of the month so don't chase but I'm strongly considering a MW HAPZ1.
Knghifi, good to hear you find my ramblings useful. I don't know enough about ee to second guess Dan's designs. I only know what my ears tell me. The MW HAPZ1 is a very good digital source. Sure wish we had more to choose from on DSD downloads.

I see that the MW DAC has been released. I have no doubt that it is everything Dan says it is. The price, plus the price of a transport or computer system, would put that approach at a substantial premium to the HAPZ1.

Brownsfan, I'm also lurking in the shadows and making note of your experiences. Keep it going.

Thanks Mitch, will do. The cd drive on my iMac stopped working yesterday, so I won't be doing any new transfers until I get it fixed. I guess I can struggle along with the 793 albums transferred so far until I can get if fixed.

I've listened to the Ligeti "Ten pieces for Wind Quintet" 3 times over the last 3 days. We are not quite there yet. Still need more burn in. Once I get another couple hundred hours in, I will bring in a good pair of NOS 6922s to compare with the 6GC7s. I'm open to suggestions.
