Modding the PS Audio Directstream DAC MK1 and MK2

BTW just so everyone understands the 298D series is not an electrolytic cap.  It's the new Vishay Solid Tantalum Chip Capacitors MICROTAN®

We use these as they are the largest value available that will fit in the 0805 space and has a low ESR, and 0.01 CV DC leakage value and are rated to operate over the temperature of +85 C.

We tested many capacitors and found these to be the best fit and best sounding.

Here is the data on the 298D

I don't understand how this thread has become a pissing contest !

I read the modifying a Direct Stream DAC Mk1 thread on the PS Audio forums several times , all 5000 + pages . There were a few people who obviously had the technical ability to offer suggestions for modifications to the DAC . The designer , Ted Smith included . Some did the mods themselves , others opted to ask the likes of jkrichards would he be prepared to do the mods for them . For me being in Australia meant that sending the DAC to the USA wasn't an option . So I purchased the parts  from  jkrichards and had them installed locally . APS transformers and vcom mod capacitors . I could have purchased the MK2 DAC but at $14000 AU it better be a hell of a lot better than the Mk 1 . So my starting point was to upgrade the MK1 . Best choice I could have made . I finally listen to the music and not my system . The comments about increased , cleaner Bass and mid range are true .The sibilance that I heard on some tracks is gone . And yes I did demo the MK 2 .

I couldn`t  be happier with my choice .  So why am I telling you all this ?

I thought the comments "It’s because you are a good seller." are unfair to jkr .Read the forum people asked jkr .  

If those upgrade options weren't offered , then I would not have had the opportunity to choose to make the changes to my MK 1 .

I for one felt that there was that much enthusiasm for the mods of the Mk1 on the PS Audio forums that there was a push against it as it was taking sales away from the MK 2 .
