1 Using your VRE-1 Pre amplifier Congratulat ions on your pu rchase of the VRE-1 p reamplifier. Th e VRE-1 is simple to s etup and operate, but that sim plicity belie s an e xceptionally sophisticated design that includes a great deal of innovative thin king and t he best parts available today.
2 Preparing for use - locating your VRE-1: Your VRE-1 has a lot of wonderful attributes, an d one of th em is the fact that neither it nor its power sup ply produce appreciable heat . In addition, the Corian chassis is fa irly imm une to heat, so t he VRE-1 may be i nstalled in an enclosed cabinet.

7 The Powe r Supply The V RE-1’s compan ion power supp ly provides carefully tailored DC p ower fo r the prop er operation of your preamp. The “Power 1 ” conne ction provides +/- 24 VDC of choke.
8 Please Note: The VRE-1 is a h and-built work of “industrial art.” It is a b eautiful object, and a great deal of effort h as gone into its creation. I ronically , because it is hand-made, you may f ind small blemishes that do not occur in the routine perfection of mass-marketed consumer goods.
9 This is important because I cannot fu lly break-in your VRE-1 before sh ipping. Your preamp has been thoroughly tested a nd listened-to, but this is just the beginning.
10 Acknowle dgements This project has been in development for a long time, and I sincerely thank everyone who contribute d in any wa y to its success. How ever, th ere are a few people I would like to.

13 Tuning the Stea lth power link cable Your VRE-1 use s a custom-b uilt power-link cable from S tealth Audio Cables. This cable inclu des a carbon-compo site sleeve t hat will slide along its length. The position of t his slee ve has a “tuning” effect - m oving it will affe ct the sound of your pream p to some degree.
14 Using the XLR-to-RC A ba lanced i nput adaptors As stated in the owner’s m anual, all 4 of the VRE-1’s inputs are actually balanced. I chose the connector arrangement based on a best-guess estima te of what most audiophiles are l ikely to have in their systems - one balanced s ource (X LR), and the rest unbalanced (RCA).
