Teac Reference Line UD-501 USB DAC "DSD" - Page 20

post #286 of 299

In what way are you using the unit that buffer size needs to be small?

 

Also buffer is usually measured in samples not time.

none. it is fine actually. I was just noting there is some difference. jriver states in time(ms).

post #288 of 299

Is that prebuffering or output buffer?

post #289 of 299

it is on the asio setup page. I am figuring that is the output buffer. the streaming media buffer is on a different page. I noticed it was skipping so I increased the hardware buffer and fine. as you said it  does not matter for listening. that only matters if you are recording or dj'ing afaik.

Exactly, it's really only an issue if you do digital tracking. For music production or dj'ing.

Can anyone compare to Benchmark DAC1?

Hei...

Anyone with Teac UD501 can post late impressions about it?
I'm getting one and wanted know more about people's experiences.

I quite like the piece. I really wanted something that would work perfectly in Linux and play DoP. I compared this DAC to many other pieces that cost an order of magnitude more and found that I couldn't hear enough of a difference to justify continued search for now.

So, did u compare them yet?

post #297 of 299

I don't know about the non Muses Essence one, but I had a Muses one, and I currently have the UD-501. I used boed out in Balanced mode to a Bryston BHA-1 to a Black Dragon cabled Sennheiser HD-800.

 

Hands down, the Teac was much more neutral and revealing. The Muses sounded pleasant but colored everything with the Muses sound, which got frustrating after a while, as it also tended to sound slow. The Teac was just right, not too revealing, not too warm, not dry or brittle (which is the danger with this setup, unfortunatley). 

 

Hope that helps.

Frankly I was surprised at how substantial the build quality is on this unit for its modest cost. Even with its substantial end caps removed this unit is pretty heavy and very stoutly constructed for a unit that only retails for 849 usd. I also tried to locate a fuse within the unit. Damn if I can find one I did not see any fuse at least one that I can find within the unit. If there is a fuse in this unit teac did a great job concealing it. I saw another post with in this posting that said another person could not locate a fuse within the unit either. So I am not the only one who could not locate a fuse inside the well populated volume within this very substantially built unit. Damn I had hoped for a good bump in the units performance by upgrading the fuse but if there is no fuse that is not going to happen.

  The one thing that I can say about this unit after ten months of use that it definitely is at its best when you use the balanced outputs. The sound is decent from its single ended inputs but it performs  noticeably better when you use the balanced outputs.


 I have checked the inside of the unit too and there is no fuse in the unit. I believe the unit has some type of shunt to protect it. I do agree with your findings regarding the sonics. It sounds ok single ended but sounds noticeably better in balanced output mode. I am using nordost heimdall version 1 balanced cables to my emotiva airmotiv 5s on my desk top and it sounds pretty decent. To improve sound try a upgraded power cable this does make a difference with the teac.I have had my unit for awhile and have been satisfied with its desk top performance. The headphone amp is not bad but my dedicated headphone amps do sound better. I wish that teac had used a better volume pot in the unit like a alps blue velvet unit. The pot they used looks out of place when you look at the build quality on the rest of the unit. I guess they had to cut some where to keep the cost of the unit below a thousand. A better pot would have bumped up the performance of the headphone amp a bit. I bought my unit from the teac factory store. The last time I checked teac has bumped up the price on the unit from when I bought it. At the time I payed  749 usd for mine.

Well I am concerned because the port should be silent. I didn't notice any hum with my UD-H01.

Update:
According the Noise Level Analysis here http://archimago.blogspot.com/2013/05/measurements-teac-ud-501-pcm-performance.html
Could I be hearing the 60 Hz powerline hum around -118 db? 


I hear a Hummmmmmm as we'll coming from the RCA into my Woo Audio WA6-SE; Very annoying - I was about to start changing stuff when I remembered what archimago had said... I didn't hear a thing via XLR going into my Mjolnir or HA-1 or my HA-1 into the WA6-SE via RCA.

I gotta sit down this weekend and give it a really good listen... I hope I was wrong... All my equipment power is coming via a Monster AVS 2000 then a Monster HTPS 7000 then SR TESLA SE T2 cable... So rfi/emi/ground loop shouldn't be an issue... Methinks

Will report back my subjective analysis...

Peace...L3000.gif
