AudioQuest JitterBug

AudioQuest points the finger of improvement firmly at jitter and packet error reduction caused by excess electromagnetic and radio frequency interference. This is a fairly common mantra in modern audio, but it is fair comment that audio devices like DACs and solid-state preamplifiers are not particularly happy receiving a signal drowning in interference, and typically things that cut back noise currents and parasitic resonances in especially noisy environments (such as computers and NAS drives) is commonly considered a good thing.
Most of these RFI, EMI, and resonance control devices work along analogue lines (such as Entreq or Vertex AQ boxes), and frequently use elaborate mechanical grounding techniques. These come at a fairly healthy cost to the end user. The little JitterBugs work in the digital domain and cost £39. Each…

In other words:
cleans the RF/EMI but NOT THE JITTER.
Less noise -> less
digititis -> sound more analog -> more natural/credible and with very low noise/interferences in the system:
the music fills the room (with good records off course). More detail but without
fatigue.
Würth 150 kHz ferrite is cheaper and probably more effective.
