JK Richards PS Audio DSD MKI transformer upgrade


I sent my PS Audio DSD MKI to JK Richards to be fitted with the upgraded nickel transformers and VOCM caps. Should be arriving today. Will follow up with a comparison review  once the upgraded DAC settles in. 

Here is a link to the lengthy thread covering the evolution of the PS Audio DSD mods.

Only upgrades are available at this time.  Both the Signature Series and Signature Series PLUS upgrades and Special upgrade pricing for current customers. If you purchased an upgrade you may be eligible for the Signature Series PLUS Upgrade for VIP customers.

We have some exciting news. We have been working on a new Directstream DAC upgrade for the past six months and have finally released it.

Our new Limited Edition Signature Series PLUS DAC.

The Limited Edition is the latest model in a series of the finest and most successful DAC upgrades ever made. Providing even more presence, weight and definition than that of its predecessor, the Signature Series PLUS.

The Limited Edition clearly redefines the state of the art at a price that is not inexpensive but represents extraordinary value.

While differences in recordings are immediately apparent, the Limited Edition connects you to the intent of the musicians and the soul of the performance, drawing you in even more.

This unit extracts the room ambience like no other. You can clearly hear the room where the original recording was produced.

Only by hearing it for yourself will you fully appreciate the sonic advancements unveiled by the Limited Edition.

The Limited Edition possesses great bandwidth and resolving power combined with a purity and naturalness that is uncanny – grain and electronic artifacts are simply absent. Bass impact, depth and control is startling, while music ebbs and flows with a dynamic life that is rarely experienced outside the concert hall.

 

This upgrade includes the following upgrades in addition to our Signature Series PLUS upgrade:

1- Our New pure copper IEC AC input socket.

2- Silver AC input wiring.

3- A 50% larger pre-regulator capacitor.

4- Our discrete 5 Volt regulator for the digital input board.

5- Additional post regulator capacitor.

6- Hand-picked Rev.2 transformers.

 

Our new pure copper IEC AC input connector.

New capacitors we use.

Our new 5v discrete regulator for the digital input board.

 

Starting this Friday (11/15) we are giving customers 10% off  site wide until the end of November while supplies last.  This sale excludes VIP pricing upgrades.
