Celestion Ditton 66’s. ‘Upgrade’ to modern speakers consequences?

Thanks guys, appreciate the feedback.

@jasonbourne52 thanks for the reassurance and, yes, I think these two Yamaha amps have excellent reputations and pedigree. Internals share some similarities with Accuphase, especially these early models, and the P2200 apparently still in service in many LA recording studios.

@petg60 nice, even flattered, to think that the Ditton 66’s are so special that the Yamaha amps are the weaker link in my system but would be interested to hear what their failings might be? My understanding is that the Dittons are very efficient and don’t need much power to sound loud. However, high current and high damping factor amplification allows the Dittons to perform to their fullest potential.

Would be good to know if there’s another level to be achieved by purchasing more contemporary speakers. Would it be a ‘higher’ level of audio quality, or just a ‘different’ audio signature?

If you like that British sound signature try to audition  some modern speakers along the same lines - Harbeth, Monitor, Tannoy. I actually have a pair of Ditton 100s in the guest room that I like very much.

I owned Ditton 66's in the late 70's  They are quite power hungry speakers and that is probably why it was recommended you upgrade the amp.  It does depend on the room size and how loud you like it.

Thanks for the advice everyone.

The P2200 delivers in excess of 200W per channel.

@stereo5 what power level would you suggest I should be looking for?

@jtcf I’ve always liked Tannoys.. thanks.

@stereo5 here’s some specs.
