Yes I heard the Rossini Apex it makes the old Bartok sound like a squishy toy.
Apex is 3 improvements. The processors are twice as fast, the software is sleeker and analog stage improvements. It’s night/day. It’s more natural and less digititus.
I would upgrade the Bartok or save 40k for the Rossini Apex and buy a better DAC.
don’t master clock anything until you can upgrade the fundamentals.
the Lina is a bauble for headphone children to upgrade from their Chinese made Holo May that isn’t as dynamic.
OR you can just buy a Mola Mola Tambaqui and sell your Bartok and save thousands and thousands and have a better DAC then the Bartok Apex will ever be!
