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

@stereo5 here’s some specs.

Don’t know the Ditton 66s but I helped rewire some 44s.

They were quite different to most modern speakers.

How to describe?

They had a more looser, faster, energetic bass for a start.

The giant bass driver must have played its part.

The sound was engaging and propulsive, brimming with life.

Downsides?

They were definitely more coloured than speakers of today.

I can’t describe this colouration, but it was there, a slight tint across the board.

If you like this colouration, then I’m afraid you’d have to spend an awful lot of money to improve on that energy.

If you don’t, then almost anything of today will be more neutral, if not more dynamic, full of life, energy and zest.

A lot depends on what you mean by large high quality floorstanding speakers manufacturered in the last decade or so.

I can remember the Dittons sounding balanced, engaging and doing some things pretty well like bass, depth, with natural mids and highs. Excellent for atmosphere and slow music but less when things got too busy. If you like that presentation but your music preferences are varied check for modern speakers with more transparency and better separation.

I would look at upgrading your preamp to something like a Supratek.Your speakers and power amp are very good.A good modern tube preamp will really open the sound up and give a more 3D sound.That has been my experience with good vintage three ways like Gale 401s and Celestion Ditton 551s.

I have Ditton 66 speakers and they are a prime example of how a speaker, compared to changing technology, remains fndamental and does not change a lot over time.  Many have tried to replicate the Celestion Ditton 66 Studio Monitors, but they have a unique sound all their own.

I drive mine with a McIntosh C48 preamp and a McIntosh MC500 power amp (2 x 500 watts).  I didn't plan for this combo, it just fell into place and there is not one part of it I would change.

I had Celestion Ditton 15s before and prior to that, all PSB and Paradigm speakers.  I am a strong believer that the old gear, before it was made offshore like most speakers are today, sound better.  I would rather spend less money on something older and better sounding then pay the jacked up prices and buy something lesser at todays prices (produced offshore and assmbled locally).

Even better for you that you got them recapped.  I bought all new caps out of France and plan to tackle that myself some day.  Just as a matter of interest, I added an SVS SM-2000 Pro subwoofer to my system which compliments the Ditton 66 around 40 Hz
