We are pleased to announce the finalization of our scope to the following upgrade option:
We are designing an upgrade board that will allow as many as three digital inputs to be added to existing ModWright Modified players, tube or SS, thus allowing the ModWright player to act as both player and DAC.
Digital inputs will include SPDIF (RCA and/or BNC) and AES/EBU (XLR) inputs, USB not included
. The decision to not incorporate USB was based on the fact that to do so would compromise THIS design. You can easily use a variety of external USB/RCA converters, such as those from M2Tech, that allow for up to 24/192 hi-rez data.Design Scope and details below:
Design scope has been finalized and expanded. Digital input design shall include custom vcxo control algorithm, data buffeting and other circuits to achieve less than ~20ps jitter levels. This is the proprietary design of Alex Dondysh, digital engineer (former owner of 3Dimension Audio).
this appraoch was chosen over merely using a standard digital input receiver with internal PLL circuit, typically producing jitter levels on the order of 200ps or more! It DOES add cost to the design, but I feel the performance MORE than justifies the end cost.
This is not to be confused with the master clock, internal to the player. The purpose of this clocking/buffering circuitry is to minimize jitter of external digital data, feeding the player's own DAC. This is to maximize performance of the modified player as a DAC for external digital source. In this configuration, the circuit consists of our ultra-low jitter digital input circuitry to the player's own DACs and output to ModWright's own analog stage design.
Oppo BDP-83SE and Sony XA-5400ES units will be the first units available for this upgrade.
SPDIF (RCA), BNC and AES/EBU (XLR) inputs may be provided. Multiple digital inputs will be switchable via mechanical switch on back of player. Toggle switch on rear of player will toggle unit from player to DACPrice will be $750. Discount available to those interested in pre-ordering.ETA for release is expected to be Feb. 1
, allowing for design and testing of first article.
Thank you and please feel free to submit questions, comments and feedback here!
I have added a link to forward to this new thread, from a previous thread where this concept was introduced and feedback sought.
