Well Lak, I believe you. Actually when Bob Bundus compared it to a 10k component upgrade, THAT really caught my attention. I recently did a cryo tube upgrade at 150.00 that was similarly dumbfounding in exactly the areas you described, sounds louder, more dynamic, resolving of low level detail across the board and an increase in stage depth and width and just amazing image focus all resulting in greater realism of recordings. I will certainly try one out and post my results. Thanks for the update and thread.
