Placing Instrument Separation of Large Ensembles in Recordings


I have noticed that my stereo presents solo piano recordings with more realism and impact than any others. And that’s great but I can’t just listen to piano all of the time. I will say that I have mostly zero objections to other chamber music ensemble recordings, regardless of their instrumentation. But when it comes to orchestral recordings, it seems to be all over the place. Some recordings sound like the orchestra has been divided into blocks and fitted together. So that might entail a block consisting of double basses, tympani and bassoons fitted with a block consisting of cellos, French horns and percussion, etc… In this scenario, it’s hard to differentiate instrument separation within those blocks. Some recordings sound like sections of the orchestra are divided from the center and then segmented outwards. Other recordings sound as though microphone placement is done according to their respective sections, first violins, second violins, violas, cellos, double basses, etc… And to me, this makes the most sense however it’s still sometimes difficult to make out what’s what. So is it my equipment, or is it the quality of the microphones and their placement? I will say that I find some orchestral recordings to be very good in this regard, i.e. mostly 128 cycle DSD downloads. While others make me think of sitting on the DC Beltway during rush hour. (No I don’t live in the District of Columbia). To a large degree, my thought is that this is normal and that different recording techniques will render different results. It’s simple to realize that newer recordings will have a technical advantage over older recordings. Though I have heard early stereo recordings (i.e. RCA Living Stereo) that were remastered and they sounded remarkable. Anyway, I’d appreciate input from others on this matter. Thanks!

You have a well setup, high quality system and you are a discerning listener.  What you are hearing is the effect of different microphone recording techniques. 

For a number of legitimate reasons the engineers/producers may utilize 2 microphones, 3 microphones, 5 microphones, 11 microphones or even 20+ microphones when recording.  There's also a mixing stage in the process where the sound can be modified and even reverb is sometimes added.  Do an internet search on orchestral recording techniques and also give some thought to the logistics involved with recording a full orchestra.

You're not supposed to hear individual instruments in orchestral pieces unless they have a solo part.  You want to hear the first violins as a group, not individual violins.  I believe that what most composers, conductors and engineers are aiming to achieve.  Chamber pieces are a different situation.

I hope I haven't misunderstood your point.
