DECWARE
Modified SACD/DVD/CD player with
class
A tube
output stage.
|
NOTICE:
Sony
has discontinued the DVD-685 player. We still
offer this mod to existing units. If you don't own one,
they show up frequenty on ebay.
This
SACD player features a single ended triode output
stage where the tube is visible and accessible from
the rear. It uses a dual triode (12AU7)
and may be rolled with 12AT7 and 12AX7 tubes as
well. This is probably the most popular of
all signal tubes making them easy to acquire with a
large variety to choose from.
A
new pair of gold/Teflon high quality output
jacks are also installed on the rear representing
the tubed output. The stock output jacks are
still active. That comes in handy sometimes
if for no other reason then to A/B the stock output
stage with the added tube output stage. Huge
difference.
The
tube stage features it's own power supply. It comes
on when the player is plugged in. It remains
on 24hrs a day so it's always properly warmed up
and ready to play at all times. The player itself
turns on and off with the power button or remote.
When
paired up with the 24/192KHz DAC, this tube output
stage makes this player into a true audiophile source.
|
The
Decware mods to this player involve installing a
tube output stage that completely replaces the stock
output stage by connecting directly to the 24/192
DAC chip.
The tube stage is triode, run in
class A, single-ended and uses no negative feedback.
We were able to leave the stock output stage
un-touched and fully functional. You can use
either or both.
The output of the tube stage
is slightly higher then stock ensuring plenty of
dynamics and weight. The entire tube stage
is wired point-to-point on the back of the tube
socket with no circuit boards. The tube plugs
into the back of the player making tube rolling
easy since you don't have to take any covers off.
Below
are the factory specifications of the Sony player
which remain unchanged by our modifications.

MP3 Music on a Sony DVD player is easy. Just insert an MP3 encoded disc and
press MENU. A blue screen pops up to display your folders. Scroll down the list
using the remote or front panel cursor control to select the folder you want.
The green files screen pops up to show the files in the selected folder. Select
the file you want to hear and you're done. Finding music couldn't be easier.
- Precision Cinema
Progressive™ Technology: Other DVD players detect image changes at the scan line
level-Sony's Precision Cinema Progressive (PCP) system detects them at the pixel
level. The picture is more faithful to the source-whether film or video-because
separate, optimized algorithms are used to handle the differing pixel behavior.
Separate algorithms are also used to process the moving and still parts of an
image, resulting in sharp backgrounds with moving objects that are free from
motion artifacts.
- Precision Drive™ 2
System: Past generations of Precision Drive were only able to compensate for
warped discs by moving the entire optical block, which took more time and
limited the amount of correction possible.
- Sony's new Precision
Drive 2 system simplifies the process by moving the lens-instead of the entire
optical block-for faster and more accurate error correction.
