Upgrade 20 years old crossovers

I have Etude MP1. They are twenty years plus old and have compared favorably in my opinion to Talon Firebird and Coincident Total Victory.

You can spend a small fortune on capacitors and not achieve much. If you're looking for a dramatic change in sound, you should look elsewhere. If you're looking for a fun project to learn something new, then I highly recommend digging in. Remember though, upgrades like these don't add much (if any) to the resale value. These projects are definitely for DIY tinkerers.

I haven't found cap upgrades in crossovers to make a dramatic improvement. The change can be nice, but it's subtle. Others may disagree, but this has been my experience.

Theo's advice is good... go slow and be frugal. If I were in your shoes and wanted to experiment, I'd pull out one crossover and look at the caps. In particular, pay attention to the cap going to the tweeter. It's arguably the most important in a crossover b/c it passes high frequencies and filters the lows. This is how caps color the sound. Cheap caps like Bennic, Dayton, and Solen are often characterized as having a veiled sound when used in HF filters.

If you want to experiment, I'd start with the tweeter cap. I suggest a Dynamicap or an Auricap. If you want to go with a cheaper alternative, look at Sonicaps. They get glowing reviews:

I honestly don't think new wire will make much of a difference.

Best of luck,

No doubt in 20yr old speakers, the xovers and internals will need some TLC. I upgrade xovers for many brands of speakers and I'll recommend to you, exactly what I do.

Basic:
Replace caps, resistors, internal wiring (silver coated copper), and inductors (inductors are case-by-case b/c if they are air core inductors, I just leave them alone or if they are in the woofer section of the circuit, I leave them alone)

Just by doing this, even using entry level brand caps like Kimber or Auricap, you'll take your speakers performance a very long way. This will cost you less than a pair of IC's or power cord. Not only does it cost less than an IC or power cord, you'll hear way more sonic improvement.

Another beauty of upgrading xovers, is (in my case) I don't have my customers ship their speakers, just the xovers themselves. This prevents damage to the speakers and keeps shipping costs very low.

Bottom line: no matter who does the xover upgrade, it takes the speakers performance a very long way.

Dcaudio, what did you decide to do? Did you upgrade anything?

i upgraded my B&W crossovers and it did a lot for those speakers. YMMV.
