Modifications for the Denon DVD-2910 SACD/DVD-A player.

The Denon 2910 is an excellent mid-line player for the money featuring all the state of the art video features and a decent audio section.  The 2910 is not an exact replacement for the older DVD-2900, though.  It uses balanced voltage DACs, the Burr Brown PCM1791.  This is a good chip, not quite as desirable as the current output versions, but good nonetheless since it will allow for true balanced operation from the DAC chip onward.  Two version of the Denon 2910 modification will be available.  The premium version will feature both a D-Clock and ZapFilter, and a budget version will use the D-Clock only.

The Denon 2910 uses a switching power supply, which is not the best for audio, but can be modified for optimum performance.  To credit Denon, they did use linear regulators in the circuit after the switching regulator.  I add Black Gate capacitors after the linear regulators.  This provides a clean and stable source of power to the DAC.  The ZapFilter is powered by its own power supply, I install a power relay to turn on the ZapFilter by using DC from the audio power supply. 

The ZapFilter is connected with Cardas silver wire and Neglex oxygen free stranded copper in a twisted pair configuration.  The output of the ZapFilter is connected to a pair of Cardas GRFA RCAs rather than the stock RCA outputs.  This bypasses the stock muting circuitry for the most direct and clean signal path.

This particular machine will never be as good as a modified Denon DVD-3910, but it's very close and well worth owning.

Details:

• DEXA "NewClassD" D-Clock Precision Master Clock Generator--This is a new clock design by Lars Clausen, formerly of LC Audio.  Accuracy is rated at +/-1ppm of rated frequency and the new clock generates a true square wave output.  The D-Clock has a unique microtransformer coupled output that eliminates ground loops in the clock circuitry.  This clock measures and sounds superior to the LClock XO3.  Clock modifications make any CD player sound remarkably smoother and more detailed.  Most notably, you may find yourself able to sit and listen for hours at a time when you may have become tired of listening to more than a few albums previously.

        Specifications:
                Accuracy: +/- 1ppm
                Jitter: 1.5pS
                Df(9-24V): Max 1Hz
                Control Functions: Host Vcc
                Power Supply Requirements: 9.00 - 24.00 Volts DC 20 mA

• LC Audio ZapFilter Mk II--The ultimate output stage for a CD player completely removes the need for a op-amp current to voltage stage, a low-pass filtering op-amp, and the buffering op-amp.  Essentially, it replaces 4 operational amplifier stages with a simple and absolutely superior output stage made of discreet components.  In addition, the ZapFilter includes its own power supply featuring a large toroid transformer and a schottky rectifier stage.  The sound is noticeably crisper, cleaner, more detailed, and open.  Bypassing the op-amp based output stage with this board transforms the 2910 into the real reference player because a player is only as good as its analog electronics.  It provides more gain than the stock op-amps, too.    Also included are a pair of 1,000uF Black Gate capacitors added to the ZapFilter power supply board.

        There are no coupling caps in the ZapFilter board, but rather a superior DC servo circuit.  This removes all chances

        of a capacitor smearing the sound.

        The ZapFilter is installed on the stereo output stage.  One the DVD-2910, this output is mixed-down on multichannel discs. 

        The ZapFilter may be connected to the Multichannel Front output on request.

• 12Volt Power Relay for Automatic Turn On of ZapFilter.  The addition of a relay for the ZapFilter's power supply allows the ZapFilter to be activated remotely when the player is turned on from stand-by mode. This way, the player can be left on in standby mode without the ZapFilter using power and giving off heat.

• Rubicon Black Gate 1000uF 16V STANDARD power supply filtering capacitors.  Three of these large value capacitors are installed on the outputs of the DVD-2910's switching power supply for very effective filtering.  These lower the noise floor quite a bit.

• Cardas GRFA Silver/Rhodium RCA jacks--Installed for on the stereo outputs, the heavily machined and heavily plated Cardas GRFA RCA females provide the perfect termination for your ultimate analog stage.  The Cardas provides for a better connection for your quality cables, and feature a Teflon™ dielectric.  Connected with Cardas silver wire on the DAC output and Neglex oxygen free stranded copper on the ZapFilter output, all in Teflon tubing.

• Balanced Outputs--A new balanced output modification is available for the Denon 2910.  The 2910 uses balanced voltage output DACs, and the ZapFilter is designed for fully balanced operation with no phase splitting.  The board will amplify the positive and negative phase from the DAC, so true balanced operation is available.  The SACDmods balanced option will feature Neutrik XLRs in addition to Cardas RCAs for the Stereo channels.  The balanced output modification is available in addition to the standard modification package for $75 extra.  See balanced output photos in a DVD-2910 at bottom of this page.
