This is important because I cannot fully break-in your VRE-1 before shipping. 
Your preamp has been thoroughly tested and listened-to, but this is just the 
beginning. I make every effort to present you with a good initial impression, but 
beyond that it is up to you to complete the break-in process, and to *understand* 
that it will take time. 
 
Break-in is a process of using your equipment - not simply leaving it turned on. 
You must have something playing (music or some sort of break-in signal) to get 
the job done. I feel that playing music normally works perfectly well, but there 
are special CDs and LPs made as “break-in discs” that are favored by some. 
Check with your audio dealer or music supplier if you are interested in these. 
 
The main thing is to understand that it will take some time for your VRE-1 to 
realize its full potential, and I urge you to relax and enjoy listening to music while 
it breaks-in, warms-up, settles-down, or whatever you want to call it.

Troubleshooting 
 
Problem: No sound, no lights, no nothing. 
Solution: Check your AC power connection to the wall outlet to make sure you 
are getting power; check the AC Mains fuse to see if it is blown - replace if 
necessary. 
 
Problem: You have lights and hear the relays click, but no sound. 
Solution: Your analog power link cable may not be connected properly - check for 
proper cable connection. Check the obvious - is your amp turned on? Correct 
input selected? Source playing? Check the interconnect cables to and from your 
VRE-1. Be sure you have selected a working input.
