TEAC UD-H01 USB DAC - Page 10

post #136 of 269

Hello !

 

I would like to upgrade my usb dacs.

Presently I own two very cheap units:

  1. behringer uca 202
  2. audinst mini

 

All in all i like the sound, maybe the mini is a little better than the UCA but it is still breaking-in.

I wonder if this Teac is really a step-up compared to the two usb dacs above mentioned

I have already a separate headphone amp so I would use the Teac only as a dac

Thanks for any suggestion/advice.

Regards,

gino

You know that everything depends,
On the: price you can get it for; headphones you use....
As a general rule mains powered DAC should sound better than USB powered one, but than again new headphones would change the sound much more than a DAC.
Personally I like my TEAC a lot, and would probably like it even more with better headphones (I'm using Goldring DR150) I have no troubles with TEAC drivers, everything works great using TEAC HR audio player for hi res files and optical for youtube and else, I think TEAC UD H01 is already in the land of diminishing returns so
if you want to be guaranteed that you have the best buy something like Benchmark DAC, otherwise weigh your options and listen wink.gif maybe try musical fidelity M1DAC or audiolab MDAC

Thank you very much indeed for your kind and very valuable reply bigsmile_face.gif

I have decided for a dac + separated headphone amp solution in the end

The Teac is very nice and well built

As amp i am using a Fiio e9 (old version) with both Akg 242hd and Beyer dt990 Pro (250 ohm version)

The Teac is about 350 euro new.

The audiolab is twice the price.  The M1DAC is in between i think

As you say the power supply counts a lot.

The usb cannot provide much energy at 5VDC.

Thanks again

Kind regards,

gino

Hey Gino. All I am saying is there is so many DAC's around that it is so hard to choose so just look around for best deal cause many of DAC's are quite similar in performance. I got my TEAC UD H01 from UK at a discounted price of 150 GBP plus 40 GBP for shipping. It has quite a nice headphone amp built-in and it's handy to have it all in one box.

You could even try NWAVGUY's ODAC which is quite cheap but very nice http://epiphany-acoustics.co.uk/products-page/dacs/e-dac-24bit-miniature-usb-dac/

and see if you hear an improvement.

Good luck in your "quest"

Hello !

I have an opinion on this much debated issue

I think that measurements tell a lot, if done correctly

When i see tests on amps with pure resistive loads I am puzzled

Which is that headphone that is a pure resistive load ?  all are complex and tougher loads than a simple resistor

Instead I like very much Inner Fidelity tests because they are carried out directly on headphones (even if they do not say with which amp by the way)

And the same applies for line stages

I think that DACs are all quite good.  Power supplies and analog stages make the difference

And I am pretty sure that the Fiio is weaker in both aspects compared to the ODAC and even more to the Teac

Thanks a lot again

Kind regards,

gino

Is anyone able to get support for all the sample rates using toslink optical? I can only seem to get 44.1,48, and 96 kHz working. I'm note sure if its a limitation of the digital out on my notebook or is it the Teac DAC. The manual doesn't mention any limitations with digital inputs.

No limitations for me.  The Teac hooked up to a Squeezebox Touch with the EDO add-on does 176.4 and 192 just fine.

Ok thanks. So I guess its limitations on my notebook, which uses Realtek drivers.

Anyone know a way around this? I got an Acer 6930G notebook.

Why not use USB?

I am pretty certain my macbook is limited to 96 via optical - no problem with USB.

I bought a UD-H01 as a starter USB DAC for part of a new PC set up for headphone listening. The headphones were HD650s with balanced ends connected to a nine year old Headroom Blockhead amp. The sound was good but I needed to use an equaliser to get it to my tastes, notably increasing the highs.

 

Then I bought the HD800s with the stock cable and 1/4 inch jack so all I could use was the TEAC's headphone out or a Chorda Headphone amp.

 

I am very impressed with the TEAC and HD800s. The bass is nice but a bit light if you like lots of it, but the detail is excellent. I'm learning new sides to familiar songs and with it a greater appreciations of the songsmith's art. To me and my tastes, it is a very enjoyable sound. In fact I prefer this to the HD650s and Blockhead.

Hi !

 

Just bought the UD-H01 recently . Too bad I didn't read the review in thread before I bought this DAC , otherwise I should know that the driver issue for 64 bit system earlier .

 

Personally , I like the sound from this DAC more than my previous DAC , which is Fiio E10 . However , the driver issue make the DAC is not stable enough to use . It will generate loud noise , and cracks , at unpredictable frequency . Sometimes the DAC just generate noise after 15 minutes of operate , and sometimes it runs for hours without problem .

 

So , there will be two option for me at this moment :

1) Endure the USB problem and wait for the next update from TEAC

2) Buy an additional USB-Digital interface to connect the DAC via Digital Coaxial or Optical

 

For option 2 , I'm now considering either SMSL SD-022+ , or Musiland Monitor 01 USD (version 2012) . Please , advice me which one I should buy for a better audio experience ? Personally I prefer Musiland Monitor 01 more because once TEAC's driver is stable enough , the Monitor 01 can be withdraw from the system and can use as a standalone sound card .

 

BTW , is there a practical workaround solution for Windows 7 64 bit user to operate this DAC stably ?

 

Thanks very much !

 

Regards,

Kurz

I found that most of the problems with the Teac UD-H01 is that it's seems to have been created with usage with a computer as an after thought. It doesn't communicate with the OS hardly at all. It appears as though Windows can't tell whether or not the DAC is in use or idle. After a period of time Windows times out the USB port and attempt to shut it down or lower the power allocated to the USB ports when it thinks its not in use, causeing a blue screen of death. In the Teac Manual I think it even says that Windows cannot control the DAC.

 

The work around I found is to 1. disable USB Selective Suspend in the Advanced Power Options, and 2. Uncheck Allow Windows to Turn Off This device for USB Controller in the Device Manager.

 

The downside after doing this is that Windows will not enter sleep and the screen will not turn off while the DAC is turned on. BUT I find that it never crashes. And is always stable.

Also the Teac UD-H01 maynot work properly with WASAPI 3.x, so try Wasapi 2.x. The best buffer size in Foobar to set is 1380. (at least on my system)

 

P.S. Resuming from Pause using WASAPI does cause issues with Playback.

P.S.2  ASIO is an option but I found that it doesn't support Apple Lossless.
