Hi Robm321,
I am an Electronics Engineer with over 25 years insight into professional recording, I fear my technical insight may be a liitle beyond most non-engineers but I will try and clarify / justify my advise on the original question which was shoud 'I get into SACD or continue to invest in LP '....
I think you did not quite understand my technical insight or appreciate the enormity of the reality of direct to disk or PURE DSD recordings in the DSD format...read again and understand that.
1. All PCM recordings, because of the Nyquist criteria must be filtered at less than twice the sampling rate. All anti-aliasing filters introduce colorations.just like any pair of glasses you put on no matter how good..it just depends on how audible they are...they are very audible on CD but much less so on DVD-a..some people in professional circles feel you need to go to 192k in DVD-a to really make them in-audible.
Some of the most respected engineers , Tony Faulkner for example despise Anti-aliasing filters and does not use them at all on his LSO live label which he masters His thinking is there is so little info above 22.05 k that tryning to remove it does more harm than good...based on the sonic quality of his CD's I think he is right.
2.PURE DSD is not hype..knowing the inherent colorations of all anti-aliasing filters the engineers at the end of the last centuary were faced with a dilema of archiving degrading 2/3 channel analog master tapes as faithfully as possible...they were driven by the technical challenge to archive them as best as possible, not to create a new format to upset everyone.
DSD ( DIRECT STREAM DIGITAL .. the format name says a lot)was technically the best solution. They could have chosen PCM but realised after 20 years of PCM they still had the inherent colorations of Anti-aliasing filters and chose to avoid them all together...I applaud their courage & purist dedication to soving the problem staring them in the face.
3.DVD-a is a quantum leap in PCM & is arguably what CD should have been from day 1..however they did not have the technology back then...neither the HI-res DAC's, High sampling rates and in particular the technology to fit over 700 Mb on a CD.
CD made some gross compromises...
a. They assumed no audio info above 22.05 k.
b. They allowed a non-stndard Anti_aliasing filter (aka Brick wall filter) which introduced phase anomolies in the upper HF audio band which were audible but impossible to mirror immage out as the vinyl RIAA curve did...this is why Vinyl inherently sounds more natural than any CD.
I go to classical concerts every two weeks & have a good reference point...I applaud the hybrid SACD which allows us to play CD in the car etc. & then read the higher res layer in our domestic systems..I also applaud them being able to do all this for just a few dollars on the cost of the CD.
DVD initially did not offer this and are playing catch-up now.
I truly did not want this tread to get Hi-jacked into a Format argument, I simply wanted to pass on a clearer insight into the parallels between PURE DSD and direct to disk LP's which we know and cherish so much as vinyl lovers.
Clearly, Dgad who asked for the advise realised he / she was hearing a technical break thru on hearing the Meitner...perhaps now understaning the technical hoops that all PCM recordings must go thru and that Meitner equipment is used in making over 90% of all PURE DSD's) Dgad will now have better insight as to which way to go.
Finally, I consider it historic that after 100 years in audio we can now have at home the equipment used to make the original recording & I applaud Ed Meitgner for making his purest studio equipment available to the audiophile public at such a reasonable cost.

Ceol .. which is Gaelic for Music !!
