SACD

I have a good amount of the iving stereo catalog released on sacd, most of which sound pretty good to me. 

What kind of classical music do you prefer? What composers?

Classical is relatively common on SACD so this would narrow the recommendations down.

Maybe someone else can verify, but I believe you need to make sure you are not using an external DAC with your sacd player. I believe if you do go digital out of your player into your DAC it won’t send the DSD information. I think a company or two migh make a work around for this but not sure. Maybe others here can jump in and clarify. 

jgreen19,

You are right. Most of the SACD players will not output DSD to an outboard DAC via optical/coaxial/USB connection. There are ways to circumvent that by transferring the .dsf file from SACD onto a hard drive and then playing it via a DAC of own choice. Some, probably universal, players may do it via HDMI. I have heard of a few SACD machines that would output DSD digitally but not via HDMI and those have been, I think, in the upper tier of price and performance. I have never heard one.

So, for OP, it is probably SACD played via internal DAC and output analog via RCA connection. Good news is that many SACD players are just fine with their own DACs. This being an audiophile forum, that statement may be a blasphemy, though.
