@melm yeah, well you asked me if newer recordings 'always' sound better than earlier recordings so I just answered the best I could. And, my reference to using master tapes means the original tapes from the original recording.
Microphone placement varies today just as it always has. The Jean-Guihen Queyras Dvorak recording from Harmonia Mundi is open and natural sounding so I would guess that the microphone placement is further away from the cello. Also, the same types of microphones are available today just as they were back in the day. Telefunken still makes their ELA M 251E, U47 and C12 vacuum tube microphones.
I have no desire to argue, especially where it pertains to personal preference but recording technologies have progressed over the years. Whether a record label is capable or willing to use these technological advancements is questionable.
I've been amazed at the remastering job Analogue Productions did with the RCA Living Stereo of 'Scheherazade'. This recording is a simple three track recording from around 1958. The Analogue Productions remaster is nothing short of amazing.
I did state that I thought the performance practice of works is different now from what it used to be and for me, that is neither good or bad because there are great contemporary performances and great historical performances. I believe this applies to the Dvorak Cello Concerto as well.
