The first thing to know is how exigent he is. A classical listener can have a scale of exigences which goes much behond any other kind of listener.
I dont understand the above....what is a scale of exigencies please?
My answer to the above is that you can't on that budget. I have only occasionally heard systems that sort out the complexities of complex classical occasionally, and they have cost in excess of £15000. You can ENJOY classical music for £100, but to hear it as it was intended? For what it's worth, the best system I heard recently doing this contained a push/pull valve amp (Puresound), large efficient loudspeakers (Horning) and a simple CD front end (consonance)
To
fully replicate a concert hall experience in which a full orchestra is playing is a big ask, but I think that one can get close to this, when detail is closely replicated, and only the loudest tuttis are left lacking, for much less than £15000. Certainly chamber music reproduction does not need anything like this level of expenditure. And there are ways round this problem, anyway, because modification of equipment can transform performance from competence to excellence. Headphone only systems can certainly sort out complexity
and give great dynamic range for a few grand, or even less, if one modifies used equipment.
Hi-fi used to have a credibility problem, because professional musicians would not accept its limitations. The industry took this to heart (or wallet), and today, musicians will listen to and own hi-fi because, with good selection of hardware, they can get enough fidelity to give them satisfaction. Much of the industry still provides euphony, that sells well, but with judicious selection a highly musical experience can be obtained at reasonable cost.
