I still listen and continue to buy Redbook CD’s so something that would be kind to those is important.Go R2R discrete for PCM RedBook 16/44 24/96 or DXD.
I’m trying to make the determination on overall what would work and sound the best.
NOS with tubes is intriguing as is R2R as is just a good chip set.
Delta Sigma just doesn’t cut it in comparison so far, but it is better for DSD but it's loosing ground to the newer discrete R2R’s that are out.
