The quality is dubious at best for all the sets even yours.
If you don't think that the pillerman.net site reviews your stuff to your liking don't send him your stuff after reading trhe review of the Dual Layer Set the average reader will come to their own opinion based on how it is read.
My impression is it's not much worse than yours - You can send me a copy on loan (I'll mail it back to you) or another unbiased person (AND WE SHOULD LET THE FORUM CHOOSE the reviewer BASED on System setups) so WE as a forum can best determine if it really is worse then yours.
I feel that the pillerman.com site is kinda biased toward you and i'm sure others share this feeling also.
Your set is very nice and everyone likes it hell I even love the sound on your set.
And those are the facts -
