Ironically my new DAC uses 30 year old Philips chips and manages to sound pretty good. I think implementation is everything . The newest amp technology is GaN and I would love to hear one. I am going to do a mini bedroom system and these new amps are interesting Cutting edge tech is great , it trickles down and makes affordable gear better than ever. I’m usually a late adopter of technology. More so with video , but I won’t buy into anything I don’t think is a mature technology. It took me a while to buy into streaming, starting with a Vault 2 and recently an Aurender. I waited for them to get better, have better displays, memory bays , etc and I’m glad I did. For the record , I am using a 30 year old Sonic Frontiers preamp temporarily and it sounds pretty good still. I am replacing it with even older tech ! A DHT preamp.
