Hello Fellow Audiophiles:
The new VR-5 Anniversary Mk2 has Teflon and copper foil bypass caps on the midrange and treble circuits as well as the Delphi single crystal copper cast wire. These two small tweaks add more air, detail, and clarity to the mids and highs. The value of this upgrade depends on whether or not you wish to increase the overall resolution of your stereo system. If you own very expensive system and feel the VR-5 Anniversary could have more transient "snap," this upgrade would be perfect for your system!
Best regards,
Albert Von Schweikert
