RECENT FORUM THREAD POST (2.05.13)
02-05-13: Talk2me
I just got my ModWright a few days ago, and have to concur with all the great things said. And I was coming from a $18K GNSC modded Wadia S7i and a $32K Burmester 089 CDP. My ModWright 105 blows it out the door. Dan hit this out of the ballpark. It sounds organic, transparent and with that beautiful tube magic. The ModWright 105, IMHO, is the best sounding source I have heard in my system.

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 SMPS not 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.

AUDIO MAGIC PULSE GEN ZX UPGRADE

  • The Pulse Gen ZX operates on the principle of noise absorption in the space surrounding the internal power supply within the player.
  • It simply it adds more dynamic and detail, due to a further lowering of the noise floor.
  • The Pulse Gen ZX upgrade option is $400.
  • For more information: www.audio-magic.com/Prod-PulseGenZX.html

REGION FREE PRO KIT UPGRADE

  • The Region Free Pro Kit will allow you to play multi-region discs. The Oppo BDP-105 currently only plays Region 1 discs for North America.
  • The cost is an additional $250 if installed along with the tube modification.
  • If ordered as a standalone upgrade or after the tube mod has been installed, the cost is $325.
