I'm going to disturb you a little, Ippy, I hope you don't mind. 
I am just a little older than you. I visited an audiologist a month or so ago and was horrified to learn that I have a 60% hearing loss: age-related hearing loss, normal and to be expected. I was encouraged (by the audiologist) to give him a sum of money which would have paid off the national debt of a small African country and in return he gave me two very small gadgets he called "hearing aids".
When I inserted these into my ears my world changed. For years I had been complaining that modern farming techniques and our style of urban living had denuded our nation of much of its avian wildlife. Boy - was I surprised when I wore the aids on a country walk by the tweeting racket in my ears. I thought, at first, that perhaps the climax of a certain Alfred Hitchcock film was coming true. The birds had been there all the time - i could not hear them simply because of the ravages of time on my organs of Corti.
Well, what I'm saying, Ippy, is that if you haven't investigated the state of your hearing you might not benefit from your investment in hi-fi.
My hearing aids are provided with a number of programmes - one is for music when I am listening to it in a large room (such as a theatre or concert hall) when I tried the setting in Symphony Hall it was ... magic. Another benefit I can use is use my smart phone to listen to radio programmes via Bluetooth. I can wander round the countryside listening to both the birds and Beethoven 6.

Thanks for the post H H, it looks like you've travelled a similar path to me with your hearing, it must have been some 15 years ago or more I no longer remember when exactly I first plugged in my hearing aids into both ears which according to a recent visit to the audiologist my hearing is still not showing any further loss of form, having said that NHS aids are perhaps not quiet a sophisticated as yours are, but I get on quiet well with them, they've recently been revised and these new ones do seem to perform very well.
My wife and I often frequent the Albert Hall the last one was for Carmina Burana with that expansive choir etc, the point being we are familiar with the general sound and volume of a large performance in a concert hall, the Barbican Hall is slightly different just a very slightly damped sound, emphasis on the slightly and of course this is how they seem to my 'challenged' hearing.
I'm afraid my hearing loss it due to a combination of hereditary and discos in the sixties combined, cant think why but there seemed to be something that drew me to those discos at that time?
When I play music at home it is loud when it's something I or my wife particularly like, the only trouble is where Music can be a bit of a mood thing.
Beethoven's third piano concerto is my most favourite piece, I like to hear differing performers play it they all seem to have their own ideas and, I suppose, differing ways/techniques of playing, always interesting.
O yes, we enjoy the proms in September onward, our TV is wired into the system so that the seeing and the hearing are both excellent, as is your Pastoral.
Regards, ippy.
