Reference Audio Mods Impressions of the stock and modified Sony DVP-NS9100ES units:
The Sony DVP-NS9100ES DVD/SACD/CD player is Sony's recent flagship of its prestigious ES Series, the DVP-NS9100ES boasts high-end performance sure to impress both audiophiles and videophiles. In comparison to the predecessor DVP-9000ES, this new unit does EVERYTHING Much better. It upconverts the DVD videos to 1080i via HDMI output and it can also transmit SACD audio digitally via i.Link (firewire) to a compatible receiver.

The stock 2ch sound is rather narrow, harsh and not very resolving. Music does not step into the room with clarity and liveliness. Pretty much the same as we hear out of the stock Denon 3910. This is due to the stock under-mediorce parts used in the signal path. One thing that Sony did good in this unit is they have dual power supplies (one for digital, one for analog). In addition, there is a minimalized clock circuit when using the unit as a 2ch player and they implemented the Burr Brown DSD-1796 DAC chips (same ones as the Denon 3910).

After implementing all the modifications (rebuild power supply, implement the Superclock 4, and rebuild the analog output stage), we now have a player that loses all its digital glare, grain and harshness. The Soundstage is now so wide and open with great emotional content and inner resolution. The sounds is so must larger and much bolder with great presence factor as now the music sounds like it is in the room. Bass is now so deep with inpact and refineness. Midrange is smooth and natural. High frequency extension is great with shimmering of cymbals and delicacy of fine instruments. Also, the video portion looks even better as a results from the modifications.This is really a great new unit from sony and RAM is taking it to complete reference levels of 2ch music and High Definition playback!

Recommended Modifications, Descriptions, and Prices

Power Supply Upgrades ($150 Installed)

Replace stock electrolytic capacitors in power supply circuits with Rubycon ZA/ZL series capacitors.

Improvement: These capacitors are much more open sounding, very neutral and have more speed than any other cap on the market. We have compared Blackgate FK/N, Panasonic FC/FM, Nichican Muse, and Os-cons and they are not in the same league. .

Re-wire the AC input with Audio Consulting Silver Wire, Re-engineer the power supply board and eliminate some energy robbing devices and unnecessary stock parts

Improvement: This brings more resolution, better defined and deeper bass and more sonic character. This is the final tuning of the supply to make sure the sound is balanced on the output end.

Audiocom Superclock 4 Ultra Low Noise Clock replacement ($295 Installed)

We add a reference quality jitter reduction circuit called a Superclock 3 , this a major improvement in overall sound! This replaces the master clock and offers much lower jitter rate and a extremely clean and precision signal than the stock cmos type oscillator. Expanded soundstages and accurate instrument definitions for example are the many outcomes of this major mod component. Breathtaking performance is now possible!!

2CH Output stage complete Rebuild with Audio Consulting transformers + parts ($800 Installed)

Completely REMOVE the stock Sony DVP-NS9100ES discrete analog output stage (many many active parts) and replace with passive very high quality Audio Consulting Signal Coupling Transformers.

Tech notes and sonic Improvement: The stock Sony output stage is mediorce in build and rather harsh and narrow in sound quality. However, there are MANY ACTIVE parts in the signal path, such as op-amps and transistors. There are also many resistors in the signal path as well. This is not the most optimal topology for signal coupling and HF filtering. The stock Sony design uses capacitors in the signal path for DC coupling. Capacitors in the signal path "smear" the sound or (change the timing of the music). Active parts rely on voltages from the power supply. Power supplys produce noises (from diodes and voltage regulators). In Additon, active parts produce a type of noise by themselves (ie: transistors produce a high frequency noise or commonly known as "shot noise"). This is not optimal for the best sonic resolution and noise floor. The RAM Approach for the Sony is simple: Completely remove the entire active analog output stage, and replace it with a set of very high quality Audio Consulting Signal Coupling transformers. NO ACTIVE PARTS! NO OP-AMPS! NO CAPACITORS IN THE SIGNAL PATH! NO TRANSISTORS,ETC!! Now with the transformers we can now effectively and inherently provide galvanic isolation from other components in your system. The transformer stops High Frequency noises that occur from other components in your system. Since there are no active parts, the noise floor in your music drops to a complete dark and black level. More detail comes out of the music. The soudnstage appears much larger, wider deeper with a bold lifelike stance. Our approach is considered "state of the art" and this mod will easily alone take the performance of this machine alone to a level that is unattainable by just about any stock player in existance.

Replace stock RCA single ended jacks with the new WBT NextGen connectors

Tech notes and sonic Improvement: We add a set of high performance WBT Nextgen RCA connectors for the closest to "no connector" connection possible for the single ended outputs. These are the best sounding RCA female chassis connectors on the market! The reason is they use very little amount of metal and have no eddy current issues with a large surface of metal unlike everything else available on the market. We had done head to head comparisons and these connectors lose the grain the other connectors such as cardas and vampire connectors on the market.

Upgrade Modification Options for even more performance!!

Audiocom Superclock Power Supply Unit Upgrade Option ($295 Installed!)

We add a discrete power supply for the Superclock 4 that adds another level of performance to the unit. Increased dynamics and resolution is what to be expected. We further modify the power supply with Rubycon ZA/ZL capacitors to take it even further. The clock power supply is needed to truly have a matched package with the SC4 clock!!!
