Are future improvements in Amp/PreAmps slowing to a crawl?

You know, way back on September 12, Roger offered to send one of his pre amps to Kosst to audition under no obligation to buy. He flatly turned him down. Then he has spent the next month berating him and proclaiming that there is no way his product can do what he claims. Just listen to the damn thing and form an opinion after that. Quit f***ing speculating about what it can and can't do. What do you have to lose? It takes a special kind of a**hole to act that way.

I don't recall an offer that paid 2 way shipping. For the last 4 months I've been dumping every spare dime I've got into lawyers and travel expenses to deal with a very ugly situation with my daughter. Giving Roger a fair shake at my expense hasn't been any kind of priority. Since you've followed this thread well enough to dredge up this incident as ammo to call me names with, you've surely noticed that I was abundantly polite in trying to tease some very basic information from him. His claims sound like snake oil. I'm a guy who'll call out his best friend in his own living room for treating his wife like crap. I have no compunction about calling snake oil claims what they are. 

I am truly sorry about your financial situation. You state that giving a fair shake at your expense hasn't been a priority, and I can empathize with that. On the other hand, you haven't, for one second, avoided burning him at the stake at every turn. Kind of a one way street, isn't it? Apparently the sword is only supposed to cut in the direction of your personal bias. In the same vane as you, I have no compunction about telling someone they are acting a fool when they are. Hopefully, you will get out of this financial mess and find a way to actually listen to the piece of gear you are discrediting. Of course, at that point, you could let all of us know whether it sounds as Roger describes or not. If it does, could you and would you swallow your pride enough to actually admit it?

Ironically the process has been perfected and the final version is coming out as X-12. There will be no X-13.It now has TOTAL control of the data recovered from the original recording. The Auto-Focus system has been perfected and now the holographic "display" is a full clone with no distortion and no noise. It can project the same acoustic layout including the exact spacing between objects as recorded. (at the proper volume of course) and the brain does in fact perceive it as live.

GO READ THE THREAD AGAIN, you LIAR. I do grill the guy hard, but only because after a very lengthy and civilized back and forth he still answered no specific questions, even when I literally laid out a simple template of what I and many others were genuinely wondering. I'll gladly listen to anything anybody wants to send me, but I'm not doing it at my own risk and expense. 
If you want to believe whatever jargon he slings, fine with me, but I'm over here evaluating things in a different sort of way. I'm sitting here writing this listening to a rig which, with the exception of the speakers, I've either built or rebuilt with my two hands. I'm in the habit of knowing what I'm playing with in an intimate sort of way. I'm not a man of unlimited resources. If I want to listen well I must learn, meticulously evaluate things, understand circuits, hear distortion, and discern causes and effects. I just want answers that actually mean something. I'm rather befuddled so few others do as well.
