Hi All - I'm dusting off my old system that's been sitting in a closet for 15 years because I'm tired of listening to Spotify on my echo speaker. I've got a nice powerful Haffler amp with a NAD 1600 pre-amp and a pair of Definitive speakers that have always served me well. Right before i had to retire this system I replaced those with an NAD integrated amp and that turned out to be a real downgrade - so i know and like my existing amp/pre-amp setup.
Now i just need to add something so i can stream Tidal primarily and play Spotify and other things from iPhones, etc. I'm debating where I should put my money and at what point won't i notice the difference. There are some sub $1000 "streamers" like the Bluesound Node 2i that get great reviews and seems like I can just add it to my setup. I'm also seeing some 1k-2k machines like the NAD C 658 or Rotel RC-1590 that include a pre-amp that might be an upgrade for my NAD 1600 pre-amp that is 25+ years old. Alternatively i'm wondering do i just get the best DAC i can afford and then get a cheap device to stream to it since i can't see that part of the system being differentiated between products.
My goal is best quality sound so my question is what will have the most impact on that - the streaming (getting it from Wifi and sending to DAC), the DAC itself, or the pre-amp?
Welcome any sage advice from folks that have been through this thought process recently.
Thanks!
