The DCS Rossini Apex is a slid step up from the older model yes it is worth the upgrade considering he received $20 k on the 2 year old one it just brings out Everything in the recording ,and does it with amazing naturalness .
I do want to mention cables do matter .he is using Ansuz cables Ethernet switch And D series line conditioner and A $5k switch and cables. And AAvic 580 integrated Amp,and 280 streamer.above my pay grade , but a revelation to me .
his New Borrensen X series Cryo floorstanders just dissapear into the room .
Sadly I am just working on upgrades but never to his $$ standards.
