My entire collection consists of redbook CDs (some vinyl) and I am very impressed with the sound I am getting from most. Running a Audiophilleo USB/SPDUF converter (for computer) or Arcam DV-137 disc player (CDs and DVDs) into a Bryston DAC. Have not purchased hirez or DSD files. I buy CDs and rip to computer. Unlike mapman, I keep the CDs.
Redbook Keeps Surprising
I was a Best Buy to get a memory card reader for my computer. Looked at the CDs and saw a few in the bargain bin that I would like to have, only a few dollars. Came home, ripped them with DB power amp, picked the best cover art. Transferred to my Aurender through the NAS and played away. WOW, impressive sound and I really enjoyed them both. I like the High Res downloads and my SACD collection but am often really impressed by good Redbook CD. It really is the music that counts.
