Wow, Fsmith, you really are misguided,
The Big7 was $11k full retail, and the $6K you speak of was for the 2 boxL7, less than $9K retail. They are NOT the same! 2nd hand B7s are usually around $8K.
Lampi does not force ANYONE TO upgrade and many are satisfied with their 3 year old Level 3 Dacs. Lukasz does not make new models for money, hell it causes some amounts of complaints. He does it out of a passion to improve his creations. He cant help himself from tinkering.
Greedy??? Hahahaha that is funny, as I have met him 3 times now and have been to Warsaw.He is far from making a fortune from this endeavor.
He does not have to offer $150 psi upgrades as they are build waaay over specced in the first place. Courier costs is more than that in any case.
Just enjoy the music and dont succumb to nervosa. Bricasti should sound good, but not sure it can touch the Big 7, or even a maxxed out B5....to my ears.
