Mr. Tennis, why would you possibly return the preamp because it didn't suit your listening taste. That's what reviews are for; to tell us lemmings what you liked or disliked about a certain piece of equipment and why. By describing it for the rest of us who may not have an opportunity to listen to the selected piece of equipment, you could at least give us one person's interpretation of the scenery.
On the other hand, if you are afraid to write a negative piece due to the possibility of not getting future equipment to review, then that explains your decision to return the preamp without review. If that's the case, it's another sad example of the cancer in this industry.
