Hey, I thought it would. You believed so and chose your path, the Marantz long before there was any mention of Dirac Live. I was thrilled to see it not happen, HDMI being inferior to the previous design. I am thrilled at the potential to be rid of all of the cables. That's what HDMI brought. Theta's implementation from subjective assessements, has also not degraded the sound but after all the debate actually improved it. Could sound be improved even further? The debate however focused solely on how HDMI would degrade the sound. Nice to see that apparently did not happen.
Some expensive DACs with volume control are all analog (MBL, MSB) some are hybrid (Aestethix, Weiss) and some are digital (Berkeley, DCS, TotalDac). I believe with a 64 bit DSP architecture you can implement a digital volume control with absolutely no loss of resolution. I don't really care one way or the other. I have a budget and 2 ears driving my buying decisions, not a specsheet.
HDMI is a protocol for multi channel with a completely different set of considerations. Even if HDMI is implemented sounding as good as S/PDIF, the problem is still you cannot get the signal into a 2 channel DAC or Trinnov processor without downsampling because of the licensing restriction, so you are resticted to the DACs that come with the SSP (or need to downsample). The only two machines with HDMI input, full blown DRC and good DACs in one box are ADA reference and Datasat. CBIII HD with Dirac would be number 3. Since I have a simple 5.0 system and focus on SACD the modded Oppo route beats all of these three options hands down.Edited by edorr - 9/12/12 at 2:25pm
