Teac Reference Line UD-501 USB DAC "DSD" - Page 16

post #226 of 284

tj max very true. I am skilled at that stuff. I wouldn't recommend it for the first time a soldering iron is in ones hand. the deal here was I saw the opportunity to make a $850 dac(I got for $500) plus $400 of parts into a $,6,000 sounding one. you know I have the msb and others. I just felt like doing it mainly because I knew I could. everyone is on their own with those type of projects obviously.

 

anyways if you want to buy a modded one google "tweek geek". I do not think it has a warranty for $1,600 so caveat emptor. I will say it is the best you are going to do for the price but if it poops out I hope you don't miss it. people were modding the bm dac1 and bm was getting a heap of repair tickets. albeit, the teac is less complex.

 

you know what? those mods in the links look real sloppy. that is not what I did. in fact the top is even on mine!

here is a thread from the jriver forum. guy sells benchmark dac2 after getting the teac. http://yabb.jriver.com/interact/index.php?topic=83717.msg571845#msg571845

in the other ud-501 thread here someone ditched the bryston for the teac. I have seen people ditch the McIntosh d100,naim and a bunch of others. mod this thing and you will have to spend over 10 grand to do better. stock it competes nicely with most $2,500 dacs. I said to google "tweek geek" if you want a modded one and cannot do it yourself. it is $1,600 and will blow away anything near a reasonable price. I made the same mods to mine plus very nice caps on the output filter. I still don't know about the warranty from tweek geek. of course this is all subjective. people have ditched dacs three times it's price though. I think even purrin agreed he did not test it to it's fullest ability. what I am saying is for the price,even unmodded this is sort of a no brainer. I know it was mentioned I am sounding like an advertisement but don't we all like something for nothing? on that note the msb blows mine away but come on.

I am considering buying this DAC and using it temporarily until I can find something better. Currently I am using the X-Sabre and I have a bit of a problem with its slightly hazy and incoherent treble. I also have a Bifrost Uber USB2 (which I have swapped in now) and it's a great DAC with a great sound but is slightly less resolving than I am used to. 

 

In general I agree with Purrin's ranking where he rates the Bifrost over the X-Sabre. His comments on the X-Sabre are pretty much right on. I also think I do not want to get another Sabre based DAC as it appears that the issue with the treble rendering may be something inherent to that chip.

 

I haven't heard the TEAC but I am curious about it as I can get one quickly at a good price. There are a couple of reasons I am concerned about it, one being Purrin's level "S" ranking and the other being the Teac USB interface.

 

On the plus side I have read this page (http://hifiduino.wordpress.com/2013/04/27/teac-usb-interface/) where the Teac USB setup is speculated to be a sort of in house alternative to using Xmos or other more expensive chips. As well I'm not so certain about Purrin's comments, and I don't know why he tested it with a CD transport over coax. He is right about the Bifrost/X-Sabre comparison tho.

 

So I am looking for some opinions and comparisons to sway me one way or the other. Is there anyone who has also had a Bifrost or X-Sabre and done a comparison with the Teac?

Just in case you don't know.  Purrin thinks the TEAC is a POS.  If you take his reviews and impressions that seriously like you stated in your post, you might not want the TEAC.  There are people who agree with Purrin about the TEAC but there are many who don't, including myself.  Gluck.

Pretty DAC, variety of inputs, supports a lot of digital stream formats, did I mention it's pretty? Balanced and single ended outputs. It's a DAC, nuff said.

TEAC UD-501 on Fedora 19 with MPD 0.17.3 works perfectly.
 
Their usb implementation is quite nice and is UAC2 compliant.
 
I think it might have been the commit in kernel 3.10.7
post #232 of 284

I have been following this DAC for a while. I have to admit that Purrin's decision to test it via a method other then USB is curious and such an extremely negative review is a bit of anomaly. Am I ready to jump on it?

 

I still have four DACs in the running...

 

UD-501... $750

Gungnir USB...$850

Teddy Pardo DAC-USB... $1500

Chord Chordette HD... $1700

I don't understand it either, it seems they just may not have taken the TEAC seriously in the first place and dismissed it out of hand. Purrin is really the only guy who is so negative on this unit and there are some credible reviewers who like it and say it measures well (see here). However I have never heard the TEAC so I can't say for certain. I'm going to ask the local retailer here if I can maybe borrow one for a day or two to see for myself. Looking at the board pics it seems the UD-501 could be something special, or it might be no better than something like the Xonar Essence One etc.

 

Other than this my list is pretty short for dacs I could afford:

 

Bryston BDA-2 

Schiit Yggdrasil (not yet available)

Audio GD 7

post #235 of 284

I think purrin actually agreed with me that it probably could have faired a lot better. had he tested it differently. first of all the balanced outputs are much better than the rca's. it is a better dac than headphone amp. if you make some mods to this thing it will be serious equipment. stock I do not feel there is a better dac under $1,000. dsd it it's strong suit. I think once most people get it they will realize they could go up to the bda-2,d100,bm dac2 etc. they are not necessarily better. I just pointed that out above. this is not cheap for the sake of being cheap. it is a bargain. I really think most people would be happy with this if they use it as a usb dac. understanding it is not 5 grand. on the other hand modded I say it will take down giants.

 

I do have a slight problem. I have a lighted keyboard. since I plugged in this dac the computer goes to sleep but the keyboard stays lit. I can probably fix that though.

 I have had my teac ud 501 for about ten months now and have been happy with it for the most part. I have been largely using it as a dedicated dac mostly on my desk top set up using it with my emotive airmotiv 5 active monitors using the volume controls on the airmotiv 5s to control the volume.

  I spotted a sale on the heimdall version 1 interconnects at music direct. So I thought it may be worth a shot in my computer set up. They are blowing the original nordost 1 heimdall interconnects out for $ 350 usd. I bought a pair to audition for the 30 day trial period. I bought the xlr version to try out in balanced operation with the emotive airmotiv 5s. I hooked them up yesterday and watched a couple of hours of Netflix movies. Things sound very promising with almost no time on the interconnects. After a couple of hours of usb usage I thought I might try the coax input on the teac with my onkyo 5svl as a transport. I powered things up and wow was my first impression. The addition of the heimdall v1 interconnect was a real eye opener. My rather modest desktop set up was sounding very respectable with a lot of the qualities that audiophiles appreciate. I have to say the ud 501 has really arrived at my doorstep. I am playing cd after cd now and they are sounding as good as they ever sounded in my dedicated living room set up. I had mentioned in one of my earlier blogs about the teac sounding superior from its balanced outputs. I have now been made aware of that to a much greater extent with my new heimdall v1 xlr interconnects ( My audition has gone to definitely buying them ) that while the teac does sound pretty good via its single ended outputs you have not heard what this unit can do till you hear it with good xlr balanced cables like the nordost heimdalls I am using. I hear the heimdall 2s are even better with improvements in the weight and tonality of the sound. But with what I am hearing already in my set up and at the blow out price I can not imagine things could sound much better at the 350 usd price. I recommend anyone considering balanced xlrs to give the heimdall v1 a shot. You have thirty days to try it at music direct. I say go for it I am sure you will not be disappointed at the results. Supplies are limited to what they have in stock so do not wait too long the opportunity may not last long(I am glad I have mine).

  I am now happier than I have ever been about the teac ud-501 as well.

 

P.S. now that the warranty period will shortly be over I am anxious to open this sucker up and check the fuse value so I can upgrade it with a hifi tuning supreme fuse like I have on all my equipment.

I wonder how long until we see the UD-301. It is suppose to bring 501 performance to the sub $500 price point.

post #239 of 284

I just noticed a faint hum coming from the headphone port of my UD-501 when an input is engaged "steady light". It's really obvious around 0-8 db but I still faintly hear it around -23db my normal listening volume when it's dead silent in the room. Is this normal or should I be concerned? 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 doubt it. I don't use the headphone out on it but it was dead quiet when I tried. the power regulation is very good in this. I of course made it considerably better but it is dead quiet stock. well not dead quiet on test equipment but to my ears. hardly anything is dead quiet on test equipment if it is god enough equipment. I don't really think you are hearing anything at -118 db. unless you are superman. 60hz hum below -115db is considered not an issue. I don't care what anyone says everything has that. I am wondering if some people got bad ones. the real problem with cheap Chinese gear is not the quality when it is working. it is the quality control. I gutted mine anyways so I built it myself really. now I do not have any noise to -180db. doesn't matter. I don't think anyone can hear -118. I don't think that is what you are hearing anyways. you may have a bad component in it. anyways, I wouldn't plug any dac in the wall. I recommend a power conditioner. even though I doubt that is your issue.
