T+A DAC 200 Burn-in


I have a T+A DAC 200 in my system for evaluation.  For those who have burned-in a new T+A DAC 200, how many hours will be needed to evaluate its characteristics against my old DAC?

The Rowland C1S2 is so old that it does not have a stepped volume control. It uses very high quality continuous volume controls (one for overall volume and separate pots for left and right channels to adjust balance).  My understanding is that those volume controls were so expensive that Jeff stopped using them on future preamps.  An advantage of its age is that it has Tape In and Tape Out RCAs from back in the days when we taped music.  So, I turned off the volume (just because it is not needed), and used the Tape Out (which has a fixed volume) to connect the Rowland to the DAC200 Analog Input.  
My favorite album is Russ Barenberg’s Moving Pictures, which I own on vinyl as well as 2 copies on CD.  That entire album played Linn LP12 —> Rowland —> DAC200 —> CJ still sounds better than Moon 260DT —> DAC200 —> CJ.  Without getting into the vinyl vs. CD debate, I think it is a testament to the DAC200’s capabilities as a preamp that I didn’t lose quality in my vinyl playback when the DAC200 was in the path.

He suggested that with a Meitner MA3i (3.0V output) that I could attenuate the signal level using its preamp function rather than relying on its line level output.

This is the way I have the DAC200 set up in my system. I have set T+A to -15db. This feeds to my preamp. If you head over to Audiophilestyle and check out the DAC200 thread, you will come across a thread where the user "OE333" (was the head of T+A R&D) has mentioned that you can use the DAC200 and attenuate quite a bit to be used with a preamplifier. You will not lose any resolution there.. So try that option. Click here to go to that thread on Audiophilestyle.

I appreciate your comments because you have had such positive experiences with your DAC200.

Yes, I am using the T+A DAC200 in the most optimal way that I can. I am not aware of any other user on this forum that uses HQ Player to upsample all their sources to DSD. I kid you not; but before Spotify started streaming in HiFi a couple of local (seasoned) audiophiles came in for a listen and were impressed with what they heard.

It sounded great, just like I recall having the Rowland play analog directly into the CJ amps.

That entire album played Linn LP12 —> Rowland —> DAC200 —> CJ still sounds better than Moon 260DT —> DAC200 —> CJ.

That is indeed impressive. Good to know this. I do not have LP/Vinyl and thus have no idea. Looks like you are doing a fantastic detailed evaluation. All the folks should do it - but most do not - including me. I am hoping you will find your answers soon.

Thanks for the link to Audiophilestyle.  It will take some time to get through all of those conversations. 


I noticed that OE333 believes it best to use the DAC200 at line level if using an external preamp because the DAC200 as a DAC-only bypasses the preamp stage for the fixed output.  While you were writing your comment, I was writing to the service group at T+A to ask them what output level would correspond to 2.0V if using the variable output.  I could play with this by ear, but I may wait another day to get their answer.  I wrote to them about a separate question on Thursday and received a response in about an hour (pretty amazing).  

If I decide to keep the DAC200, I will likely try HQPlayer some time in the future.  I have a thing about subscription services invading our day-to-day living.  It’s not that I can’t afford them, I am just rebelling against them.  But I may consider going there for one service like Qobuz after I’ve had enough time covering my CD collection.  GoldenSound reviewed the DAC200 a while back and was quite impressed with the quality of sound when fed DSD signals through HQP.  The DAC200 has a separate DSD circuitry which he said was outstanding.

If you haven’t heard Moving Pictures, give it a listen. That’s my gift back to those of you who have been so helpful.  It is the first disc I play in stereo stores when testing equipment.  Whenever I am having it played, slowly I’ll notice several people stopping in to listen.  I once told Russ that I may have sold more copies of that album than he has.  A great follow-up to Moving Pictures is Skip, Hop, and Wobble by Jerry Douglas, Russ Barenberg, and Edgar Meyer.

Yes, that is what we have been telling you. wink

PGGB is another option to rip all your cd’s in DSD form, which is what I used with the T+A and now with my new DAC. It can be used in conjunction with HQ Player, but I didn't use HQ Player, It is not a subscription, you just buy the licence. The disadvantage is it does require a decent computer with some storage.
