The E.A.R. power amplifier is a true push-pull design that operates in pure class A. Subjectively it has the same “family” sound as the E.A.R. 859. Listeners will find it builds heavily upon this, with an increase in authority and attack. The lower bass has real grip and feel with this amplifier, far beyond its power rating, while the treble is smoother, cleaner, and sweeter, due primarily to the lack of overall feedback. A single word can sum up the 861: ''effortless.'' It has real power and control, the power to convey the emotion of the most demanding of recordings, whether the source is analog or digital.

The E.A.R. 890 vacuum tube amplifier builds on the original circuit design of the venerable 834 integrated amplifier, but offers more power by way of the KT90 vacuum tube. Build quality and finish are to E.A.R.'s usual high standards, with a distinctive touch of luxury in the thick brass front panel, heavily chromed and polished to a mirror finish. Reliability is assured and there are no user adjustments.

The HP4 is arguably the world's finest headphone amplifier designed for use with the highest quality dynamic headphones. The HP4 uses 6SL7 valves, properly matched to the load through Tim de Paravicini's renowned transformers, to deliver nearly 1W of high quality, low distortion power into high or low impedance headphones. The output circuit configuration uses the “Enhanced Triode Mode” while the input is also transformer coupled, giving the flexibility to accept balanced or unbalanced signals from the preamplifier.
The HP4 has its own volume control, while input signals can be independently switched through to the power amplifier for either headphone or loudspeaker listening. As with all E.A.R. products, reliability is paramount and valve life is expected to be in excess of 10,000 hours.
The E.A.R. HP4 has facilities for up to five line inputs, and offers a genuine tape monitoring circuit, making a total of six inputs. A high quality volume control is fitted, as well as a panel mounted power switch. Input and output terminals are gold plated. Accommodates up to 4 pairs of headphones.
