"Where's the beef ?" is the colloquism that comes to mind as the prevailing counter-argument. 😂
Look, if you purchased DIs direct from Eric you avoided dealer markup by buying direct, but with the DIs SE you don't as they are are a dealer marked up product. The sonic improvement likley does justify this added expense irrespective of the actual cost increases relative to performance for dealer markup, but IMHO and humble opinion, and I am unanimous in this, he should jack the price of the DI's up $1,500 because that would allow me to sell my DIs for more money so I can recoup enough money to justify some of this added expense. One hand washes the other. Lol 😂 Just saying...
