Owners report that the Arcam A25 significantly enhances the low end and opens up highs, fully maximizing speaker potential when compared to other amplifiers like the Rotel A11 Tribute.

Several users noted the Arcam A25's phono stage is quieter, reducing hum more effectively than the CXA81, enhancing the listening experience.

Users report a preference for the Schiit Modi 3 DAC due to its familiar warmth, despite the A25's DAC offering a more neutral sound profile.

It is advisable not to plug the subwoofer into the same powerboard as other components to avoid current starvation, significantly improving bass depth and strength by using a direct wall outlet.

The Arcam A25's DAC is noted to outperform older models like the Outlaw Audio RR2160MkII, especially in handling jitter, despite the latter having slightly less harmonic distortion.

The Arcam A25 features a non-discrete pre-out that remains active with speaker outputs, unlike the CXA81 which may not suit all external headphone amp setups.

The Arcam A25's DAC, compared to the Bluesound Node X and CXA81, is praised for superior bass control and depth when streaming, especially noticeable in tracks with deep bass like Bjork's "Hyperballad".

Owners find the A25's internal DAC more neutral compared to the Schiit Modi 3, which some perceive as slightly warmer.

Switching from JBL 120ti to Klipsch Heresy IV speakers improved the performance of the A25's internal DAC, smoothing out high frequencies that sounded piercing with the Modi 3.

The Arcam A25's Class G amplifier design is praised for its ability to deliver tremendous bass, often comparable to much more expensive Class AB amplifiers.

The Arcam A25's mechanical volume knob requires 4.5 full turns to reach volume level 50, contrasting with the CXA81's tactile knobs, which some users may prefer.

The A25's internal DAC handles up to 32bit/384kHz, but proper input quality is crucial to leverage its capabilities.

Despite its higher price, the Arcam A25 offers modern design advantages and better DAC performance, justifying the cost over older alternatives like the Outlaw Audio RR2160MkII.

Setting the Mac's MIDI control panel to the highest quality (24bit/96kHz) improves sound quality when using the A25's internal DAC via USB-C.

The A25 pairs well with different speaker setups, offering a versatile performance whether paired with JBLs or Klipsch Heresy IVs.
