Modding the PS Audio Directstream DAC MK1 and MK2
PSA just posted their measurements. Yes they did. SINAD at best would be 70 dB. Same as what we posted last week when I was accused of posting bias measurements and badmouthing PS Audio.

Why don't you ask for the manufacturer to show measurements that demonstrate otherwise? If manufacturer can't or won't do that, then that is that and independent data remains as authoritative.

Another funny post from PS Audio forum: wudai_e 4h Also the thing with measurement, If I have a predetermined bias before hand, I can make the measurement results to support the said bias. I’d take any audio measurements with a huge grai...

Posted on other site. Baldy 3h Not sure why someone would want to bad mouth PSA so much except for profit or just to be mean. Life is too short for that kind of shtuff. Also without PSA his transformer business would be non existent so n...

Agree.  Both the MK1 and MK2 sound so much better than they measure.

Here is a FFT plot of the MK2 with the new Massive firmware.  Note the distortion is worse than with the last firmware.  This new massive firmware is almost impossible to measure the actual noise floor. MK2 with Massive FW:   The MK1 has bett...

We never received any PM or the likes from you. Perhaps you are going about it the wrong way? It’s easy to reach me here. Directstream MK1 and MK2 transformers.

PS Audio was made aware of these issues in March. They are still building them this way😶 I just can’t wrap my head around the fact that they let them go out the door this way without the production manager catching these mistakes.

Here are the transformers we install in the MK2.  The MK1 transformers are not the same.  
Modding the PS Audio Directstream DAC MK1 and MK2
Over the past month we have been upgrading many of the PS Audio Directstream MK2 DAC with our nickel transformers and have discovered very poor build quality on every one. We ended up having to offer to fix these defects as we don’t like sending ...
