TEAC NT-505 FUNCTIONAL REVIEW

 

On a 1-5 star rating:

5 stars for the DAC/Preamp (considering its price point)
4 stars for the Controller App. (works well with a few annoyances)
3 stars for the documentation.
2 stars for no WiFi.
1 star for its native file handling capability BUT with a freeware software solution it becomes 5 stars (see below).

This review is more focused on providing a review of the functionality of the DAC of those things that may not be obvious from the documentation. To keep this as brief as possible I am intentionally not restating what can be found in the product documentation since you can read this for yourself.

While I am calling this a review, I am purposely not saying much regarding sound quality which is so subjective and system / room dependent. But I will say I am very happy with the sound quality of this DAC. I upgraded from a Bluesound Node 2 and realized significant and noticeable improvement in sound quality plus higher resolution and DSD.

The controller app itself is pretty good but a lot of its functionality is not documented so you also have to figure it out on your own. Once you do you will realize it’s pretty good. It just takes some time to get used to. There are a few functional annoyances but that may just be because I am used to using the BluOS app.

STREAMING SERVICES work very well. I tried it with both Tidal HiFi and QoBuz HiRez. The MQA decoding of Tidal sounded excellent, so good I am not renewing my QoBuz.

REQUIRES A HARD WIRED ETHERNET CONNECTION because the controller app will not work unless the DAC is directly connected to your router via Ethernet. You should not purchase the NT-505 unless you have a hard wired Ethernet connection available. The DAC does have both coax and Toslink inputs so one could use an external streamer connected to the digital input on the DAC but then you would have to use the streamer’s controller app and none of the other functions of the NT-505. That really wouldn’t make sense.

MUSIC FILES ON A SERVER OR NAS: The native file handling capabilities of the NT-505 are awful if you have a large number of music files. It is slow to load and every time you turn on the DAC or your controller app it seems to take forever to re-load. I was ready to return this DAC until I noticed a single line in the documentations were TEAC recommends third party free ware called MinimServer to access and manage music files instead of their own software. You MUST use MinimServer if you have any significant amount of music files in your library.   MinimServer is very fast to load large amount of music files and more importantly maintains the index of music files in the server’s memory even when the DAC is off so it doesn’t have to rebuild the index every time you turn on the DAC. MinimServer performs very well with 1T of music files that I have stored on a remote PC. If you have a NAS compatible with MinimServer you can install MinimServer on the NAS and then use another free software called MinimWatch on your PC to configure and control MinimServer. MinimServer and MinimWatch are both very well documented and a Google search will get you all you need to know.

MUSIC FILES ON LOCAL USB DRIVE: The local USB port on the front of the DAC is intended for USB thumb drives but with this configuration you can’t use MinimServer and are limited to using the DAC’s native file management with the limitation described above. But with a smaller number of files this isn’t that much of an issue. I tested it with a connected HD with about 200 GB of music files and it did ok but when I tried loading more the DAC choked and froze.

PLAYING MUSIC FROM A COMPUTER: There is a USB type A-B connection on the rear to connect a computer directly to the DAC but I have not tested it since this DAC can play all high rez and DSD files from the a remote server or NAS.

I am not going to plug any source for purchases except to say that I bought the DAC from a large online seller that offers a 60 day return for any reason with full refund or credit for something else. That is more than enough time to fully evaluate this DAC.

I started this thread five months ago and after using the NT-505 feel compelled to submit an update.

1. I am still thrilled with this product. In my prior review did not emphasis what a great PREAMP this DAC is because I was using it with a preamp and was just using it as a DAC. I am now using it in place of a tube preamp that costs new more than twice the NT-505. The description of this product should include the word "Preamp" somewhere because it is a Preamp/DAC.

2. I moved the NT-505 to an area of my home without an Ethernet connection. Not a problem for me because I am using my Bluesound Node 2 as the wifi streamer and connected the NT-505 to the digital output from the Node 2 which bypasses the Node 2's DAC function and uses the NT-505's DAC and MQA decoding functions. So no degradation of sound with the Node 2 as the streamer only plus I get to use the BluOS app controller which personally I like much better than the Lumin Controller App. These comments would apply to the newer Node 2i as well and likely any other standalone streamer if a buyer wanted to use the NT-505 somewhere without a hard Ethernet connection. Now I consider the lack of built in wifi a plus rather than a negative.

I try to use Minimserver to scan my music library on my Dell PC accessible from the Nt-505 but could not make it work.I installed Minimsever on my desktop PC.I installed the Lumin app on my iphone, but this app does not see my music library on SSD.Do you have any suggestions?

Get a copy of the Minimserver User Guide. It explains how to configure it.
After you install the server and the desktop icon is green, click on the small icon in the tool bar. Under properties you define which drive your music is on. You should then be able to activate Minimserve from the Lumin app. But download a copy of the User Guide first.

   Node 2i as well and likely any other standalone streamer if a buyer wanted to use the NT-505 somewhere without a hard Ethernet connection.

Now since you had the node2 hanging around, that is one thing, but at $550 it is just about the most expensive solution to needing a wired connection that I can think of.  Since you will definitely need to install this thing near an electrical outlet or six (depending on related equipment), one of those units that uses your home's AC wires as an ethernet cable should work just fine.  They usually have at least one ethernet port as well as wifi.   Some even have pass-thru AC so they don't actually use up a receptacle.  $50 or less.  Note:  Even the most hi-res recordings do not require huge bandwidth, so you don't need the fastest unit out there if its mission in life is to connect to your streamer.

I'm using Serviio as my music server.  My NT-505 had no problem finding and indexing all the music on my shared drive on my network.  Serviio is free.
