Replacing the ferrofluid in tweeters can enhance performance; it's a common maintenance task for these 40-year-old speakers.

Owners often replace woofer surrounds or donuts, crucial for maintaining sound quality due to age-related wear.

Owners recommend pairing these speakers with high-current amps capable of running 4 ohms for optimal performance, such as the Cambridge Audio 651W or Krell amps.

It's noted that replacing tweeters with non-OEM parts significantly affects the KEF 104/2's value and may indicate prior misuse or poor storage conditions.

Known for excellent response across the spectrum, but can sound flat with complex music due to possible amp or room setup limitations.

The KEF 104/2 speakers have a coupled cavity design, resulting in extremely tight bass, but they might require a subwoofer for house-shaking bass levels.

It's beneficial to pair with a high-power amp, like the Bryston 4B, to fully realize their dynamic potential.

Using a dedicated streamer and high-quality DAC, such as the Topping E30, can significantly improve sound clarity over Bluetooth.

Using the KUBE equalizer with 104/2s can correct coloration issues and extend low-end response, negating the need for a subwoofer.

Some owners recommend NW audio replacement tweeters for KEF 104/2, suggesting they retain the original sound presentation while potentially offering improved clarity.

A better amp significantly enhances dynamics, even at moderate volumes, due to the speakers' complex impedance curve.

Compared to B&W bookshelves, KEF 104/2s perform better with simpler music but may sound less distinct with busy tracks.

Compared to other KEF models, the 104/2s are preferred over the 105/3 due to their unique sound signature and midrange clarity.

The speakers excel at rendering specific audio effects, such as the rolling thunder in Dire Straits' "Iron Hand," with exceptional clarity.

KEF 104/2s, when bought at or below market value, can be used as a temporary placeholder speaker, potentially reselling at the purchase price after several years.

The KEF Reference Series Model 2 is considered overpriced at $620, with the expectation that market value should be about $200 less.
