| Modding the PS Audio Directstream DAC MK1 and MK2 Discovered last week that PS Audio has revised both boards in the MK2. The analog board now has grounding tabs like the digital board. Also they neglected to remove the powder coating from them contact areas on the chassis making them grounding t... | |
| Modding the PS Audio Directstream DAC MK1 and MK2 My scope showing how clean the stock power supply is. The old FFT posted above is using the USB input. That is what causing the noise shown (ground loop). Not the power supply. Also there are at least two discrete filter / regulators circuits afte... | |
| Modding the PS Audio Directstream DAC MK1 and MK2 Yes. These are very new. More to come later as more are used. A panel of listeners here all agreed that the new Signature Series PLUS tops all the DAC’s we have here in a blind A/B comparison. DAC’s we have here. 1- MK1 Signature Series, 1-Mk1 S... | |
| Modding the PS Audio Directstream DAC MK1 and MK2 Ignorance is bliss. Re-posting someone else old data. This is from years ago with a stock unit. Guess you will never know what you are missing. | |
| Modding the PS Audio Directstream DAC MK1 and MK2 Anton, Antony_s0s Please get your facts straight. We don’t just do a simple Vocm mod like the weird “sandwich conglomeration you did. Who would even consider buying anything done that way? What a mess. We professionally change and add many other... | |
| JK Richards PS Audio DSD MKI transformer upgrade Complete unit. Unless you have one to trade in. | |
| JK Richards PS Audio DSD MKI transformer upgrade APS Audio Transformers is currently having a sale on the top of the line Signature Series PLUS DAC that includes the R-Core APS internal power supply in the Signature Series units. (Over $500 savings) The PLUS upgrade alone normally cost $829... | |
| Modding the PS Audio Directstream DAC MK1 and MK2 Another interesting fact is the Signature series will accept and playback DSD 128 (DSD 2X) via AES XLR.perfectly however the stock unit will only accept DSD 64. | |
| Modding the PS Audio Directstream DAC MK1 and MK2 In this configuration we use both the factory Digital and Analog fuse locations. You can pick your best digital fuse and your best analog fuse. Digital is 1a analog is 5a. We could not believe how real percussive instruments and vocals sound no... | |
| Modding the PS Audio Directstream DAC MK1 and MK2 We are very excited to announce our Signature Series PLUS upgrade. It includes our Signature Series with a very good internal linear power supply for the analog section. We even isolated the AC lines going to each power supply. We have been work... | |
| JK Richards PS Audio DSD MKI transformer upgrade It does not. The mods only work with the MK1 Sr. | |
| JK Richards PS Audio DSD MKI transformer upgrade Many months ago we set out to make the outgoing PS Audio Directstream MK1 with upgrades to the transformers and circuits, sound better than the "new" $8,000 PS Audio Directstream MK2. We finally did it with our Signature Series upgraded MK1 DAC. ... | |
| Modding the PS Audio Directstream DAC MK1 and MK2 We finished our last MK2 transformer install yesterday. Wow... Many flaws. All digital boards standoffs were completely loose. The bolt that holds the power transformer was not even tightened. It was moving around inside the case. The i2s inputs ... | |
| JK Richards PS Audio DSD MKI transformer upgrade Here is the real reason the new MK2 is failing. It is filled with flaws and QC is awful. From the flawed grounding tabs to screws crossed threaded and many never tightened. Loose power transformers and many adapter boards hand soldered makes for... | |
| Modding the PS Audio Directstream DAC MK1 and MK2 We are very excited about our new Signature Series Modded MK1 DAC. Before the new mod the DC offset averages between 3.6mv and as high as 12mv. No unit we ever received here was below 3.6mv. Most were about 7mv or more. With our new DC offset tun... |
