For most of my years in this hobby I've been of the opinion that cartridges and speakers were relatively unimportant, and that it was the turntables/tonearms that controlled the cartridge and the amplification that controlled the speakers that were the most important. I've had some highly engaging systems, all components purchased brand new, in which the turntable and amps made up over 90% of the budget, leaving less than 10% for cartridge and speakers combined.
One thing I haven't yet heard, though, is a demonstration of Alan Shaw's claim that with his easy-to-drive Harbeth speakers, something like a bottom of the line Pioneer integrated would sound just as good as any other amp regardless of cost. I don't know if it's still going, but he once posted a challenge in which he would give away a brand new pair of Harbeth speakers to anyone who could prove otherwise, with no winners last time I checked.
It's an interesting idea to me to consider that a $350 Onkyo 9110 driving some $3200 Harbeth P3ESR XD speakers might be just as effective a combination as my usual habit of reversing those numbers, and spending the bulk of the budget on the amp. Has anyone heard a cheap amp plus Harbeth combination? What did you think of it?
