The Manufacturer Will Not Be Responsible for Any Damages, 

Inconvenience or Mental Anguish That May Result From These 

Spacetime Perturbations. 

 

There is a much higher probability that when you first plug your new 

pre-amp into the wall and listen that you will not be experiencing the 

full measure of performance this product is capable of.  These are high 

bias Class A topology circuits and their performance is largly 

temperature dependendt.   We expect these circuits to heat up slowly 

through normal operation, do not attempt to augment that heating by 

any artificial means.  Temperature and performance will slowly 

stabalize over the first 24 hours of operation and thereafter will be at 

their sonic best.  Be aware however that if you unplug or otherwise 

remove power from the unit that the warm up period starts afresh.  

Please give this product at least 24 hours initial warm up time 

before attempting any critical listening.

 

 

Like virtually all modern digital product, there is no “off” in the 

traditional sense.  The XP preamps are quite “Green” a typical current 

draw for this product is 10 watts; they are designed to be powered up 

100% of the time. 

 

 

 

SET-UP AND OPERATION 

 

So much for the philosophy, physics and advantages, lets play music. 

Please read and understand the operational instructions and safety 

issues associated with this product.  We go through great effort to 

make a soundly engineered, and supurbly performing product of 

lasting duribility.
