Glare on Choral recordings, classical vocals

Dear all,

I'm hoping for some clarity on an issue of the quality of choral vocals in digital recordings. It's either my system or the recordings. There is a glare and harshness in the crescendos, and I wonder if it's natural room clipping in the studio or cathedrals in which they are recorded (the delay in some of these spaces can lead to a natural harshness and smearing of the sound), or if I have poor setup in terms of the DAC and/ or the preamp. I use a B&K PRO-10MC and a Schiit Bifrost Multibit. This setup has resolved any issues with digital glare except in the domain of choral music. Do I have to suck it up and consider upgrading to the Gungnir or another device? Should I consider a tubed preamp, maybe the Schiit Freya?

The problem is far less noticeable on vinyl, but most of my choral collection is in the digital domain. 

I've always had problems with the Tallis Scholars recordings on the Gimell label, which are almost always recorded in cathedrals. However, I did listen once to a Tallis Scholars CD on a dealer's rig with a Conrad-Johnson tube pre and Totem Model 1 Signatures, and there seemed to be much better resolution, though this was 20 years ago and I think my younger self was just blown away by the sound in general.

I've noticed that audiophiles and reviewers seldom write about choral music. Is it because they don't like choral music, or is it because it is just really difficult to record choirs well, therefore making choral music a poor choice to show off a system?

Any choral music-loving audiophiles care to comment on their experiences and solutions? 
 
Many thanks,


Paul
