ModWright Oppo 105D SACD/CD/DAC w/BYBEE MUSIC RAIL UPGRADE and Sophia tube upgrades

1 year old Modwright OPPO 105D (purchased brand new from Modwright in Nov 2015), with original remote, accessories, manual and box. 

Everything is in perfect condition, both functionally and cosmetically. ZERO issues.


It has the optional BYBEE MUSIC RAIL UPGRADE and the original ‘Truth’ umbilical cord. 


Additionally, the stock tubes were upgraded to a pair of Sophia 6SN7s and Philips NOS 5R4GYS at the time of purchase.


The upgraded tubes have seen 200 - 300 hundred hours of play time since my purchase.


I will also include all the original stock tubes with close to zero hour of usage  
 

Tube mod includes:

• Total redesign and replacement of single-ended and fully balanced output stage with our own tube analog stage (6SN7 driver tubes).
• External PS (new design) with one rectifier (5AR4, GZ34, 5U4, 5V4 and equivalents) and two voltage regulator tubes (13EM7,12EM7 and suitable subs.)
• ‘Truth’ umbilical of our own design.
• Upgraded Cardas GRFA series RCA’s for stereo outs.
• Upgraded Furutech cryo-treated IEC.
• Highest Quality resistors in key signal path applications.
• All signal wire = 99.9999% pure, cryo-treated solid-core silver wire from Cardas metals.
• Upgrades to internal stock power supplies (Linear power supply replacement for stock SMPSnot included )
• Damping mods for chassis and transport.
• External supply available with optional ‘Hole’ to allow for use of taller, larger diameter tubes other than 5AR4/GZ34 (just ask).

Optional Upgrades:

BYBEE MUSIC RAIL UPGRADE

• Installation of Bybee rail at critical voltage to DAC = $225 per rail. This upgrade can be installed on both the 2CH DAC and the MCH DAC.
• The purpose of the Bybee rail is to SIGNIFICANTLY (MEASURABLE!) upgrade the quality of the power feeding a critical voltage to the DAC.
• This translates to lower jitter and a lower noise floor. This is an entirely different technology than Bybee purifiers which we have also used for years now with great success. This is a breakthrough technology!
• The upgrades improves resolution, detail and decay which leads to broader sound stage and a more natural musical presentation, with out edge or glare.
