Super Linton system notes: speakers, room, amp and DAC

Starting point

The reference taste in this system was not a bass-heavy or treble-forward one. The anchor was the Sennheiser HD600: natural mids, believable vocals, low fatigue and little interest in exaggerated sparkle. That matters because the loudspeaker decision was less about buying the most detailed speaker and more about finding a speaker that keeps tone convincing in a large room.

The existing speaker was the DALI Ikon 2 MK2. Its hybrid tweeter system can give a lot of perceived air and wide treble dispersion, but in this case that presentation was experienced as too bright. The goal became clear: more body, more vocal naturalness, less upper-frequency emphasis and better low-volume fullness.

The final system context was:

• Wharfedale Super Linton speakers on their matching stands
• NAD C 325BEE integrated amplifier
• WiiM Mini as digital streamer
• Chord Mojo fed over optical from the WiiM Mini, then line-out into the NAD
• A large room, roughly 7 m by 6.5 m by 3 m, about 45.5 m² and 136 m³
• Normal listening around 60-65 dBA, which is objectively modest

Why the Super Linton made sense

The Super Linton fits the HD600-style preference better than many modern compact monitors. It is not primarily about etched detail. It is a large standmount with warmth, scale, vocal body and enough bass output to avoid sounding thin at low volumes.

Wharfedale specifies the Super Linton as a three-way vented-box standmount with a 200 mm bass driver, 135 mm midrange driver and 25 mm soft-dome tweeter. Published specifications list 90 dB sensitivity at 2.83 V/1 m, nominal 6 ohm impedance, 3.9 ohm minimum impedance, and a recommended amplifier range of 25-200 W.¹

Compared with the Ikon 2 MK2, the expected changes were:

The main risk is not that the Super Linton is too sharp. The risk is the opposite: in a boundary-loaded placement, it can sound too full or bass-heavy from the side because bass radiates broadly while treble narrows off-axis.

Super Linton vs KEF R3 Meta

The KEF R3 Meta is the obvious technical comparison. It is a compact three-way standmount using KEF's Uni-Q driver array with MAT, a 165 mm bass driver, 87 dB sensitivity and 4 ohm nominal impedance.² Independent measurements also show a minimum impedance around 3.17 ohms at 142 Hz.³

The R3 Meta is the more precise loudspeaker. It images more sharply, has more controlled directivity and presents information in a cleaner, more explicit way. Erin's Audio Corner describes the R3 Meta as having excellent directivity, which helps reflections integrate more evenly with the direct sound.⁴

That does not automatically make it safer for someone who found the Ikon 2 too bright. The Ikon brightness comes from a different mechanism: wide, sparkly high-frequency output from the hybrid tweeter arrangement. The R3 Meta is not bright in that same way, but it is very clear and revealing. For a listener sensitive to upper-mid and treble energy, especially in a reflective or placement-constrained room, the R3 Meta can still be perceived as too exposed.

For this specific listener, the Super Linton was the safer match. The R3 Meta remains the more technical choice, but not necessarily the more comfortable one.

Room and placement mattered more than gear

The room is large, but the speakers could not be moved freely. The practical placement had the speakers near the front wall, near furniture and with a large TV between them. That combination matters more than small DAC differences.

When a rear-ported or bass-reflex loudspeaker is close to boundaries, the room reinforces the low end. From the side, the tonal balance can become bass-heavy because low frequencies remain strong off-axis while high frequencies reduce more quickly. This is not a defect in the speaker. It is the expected interaction between radiation pattern, placement and room gain.

Since the speakers could not be pulled forward significantly, the realistic fixes were:

• Use PEQ cuts in the WiiM Mini rather than changing hardware first.
• Try small toe-in changes to increase direct sound.
• Use bass trim sparingly on the NAD only if needed.
• Consider partial port damping only after PEQ, not as the first move.
• Accept that side-room listening will sound warmer than the main seat.

The main diagnostic conclusion was simple: if 62 dBA at about 2 m feels loud, the system is not short of power. The room is storing and reflecting enough energy that subjective loudness rises before the SPL number looks large.

NAD C 325BEE power and real listening levels

On paper, the NAD C 325BEE is not a large modern integrated amplifier. NAD literature and service data list it at 50 W per channel into 8 ohms or 4 ohms, with dynamic power figures higher than the continuous rating.⁵

At first, the room size suggested that the NAD might be the bottleneck. A 45.5 m² room is large enough that realistic room-filling playback can demand more current and headroom than a modest integrated amplifier can comfortably supply. That would matter at higher levels, especially with bass-heavy music.

Then the actual listening level changed the conclusion. Around 60-65 dBA at roughly 2 m is quiet to moderate. At that level, the amplifier is operating in the first watt or two for average playback, with peaks still well inside its comfort range. The NAD is not the practical limiter at those levels.

The Super Linton's higher sensitivity also helps. Compared with the DALI Ikon 2 MK2 sensitivity figure of 86.5 dB at 2.83 V/1 m listed in DALI's IKON MK2 specifications, the Super Linton's 90 dB sensitivity means it needs roughly 2.24 times less power for the same SPL, assuming similar impedance behavior over the relevant range.⁶

The remaining caveat is bass current. The Super Linton can dip to about 3.9 ohms, so it can still ask for current in the low frequencies. At the measured listening levels, this is not a serious issue. At louder room-filling levels, it would become the first place the NAD softens.

DAC choice: Mojo, Rega and the WiiM chain

The active chain was clarified as:

WiiM Mini digital out via optical → Chord Mojo → line-out into NAD C 325BEE → Super Linton.

In this chain, the Mojo is the active DAC. Chord's own Mojo documentation describes a 3 V RMS line-level mode for connection to a preamplifier, set by pressing both volume buttons while powering on.⁷

The Rega DAC and Chord Mojo are different flavors rather than an obvious hierarchy in this system:

Because the Super Linton and NAD combination already leans full and forgiving, the Mojo is a sensible stabilizing component. The Rega may be more attractive if the system feels thin, but that was not the main problem. The main problem was boundary-loaded bass and room energy.

An iFi tube buffer was also available but not connected. In this system, adding it would be a flavor experiment, not an upgrade. It may add warmth and harmonic density, but it can also soften bass edges and reduce clarity. With Super Lintons already providing body, leaving the tube buffer out is the cleaner starting point.

Using PEQ instead of changing boxes

The WiiM Mini's PEQ is the most useful tool in the system because the strongest audible issue is likely bass reinforcement, not DAC quality or amplifier stress.

Given the room dimensions, the first axial room modes are roughly in the mid-20 Hz range for length and width, and around 57 Hz for the 3 m height. Real rooms also create combined peaks and boundary effects, so likely problem areas are around 45-60 Hz and 70-90 Hz. Exact correction should be based on measurement, not guesswork.

A cautious starting point is:

Q controls the width of the filter. A low Q affects a broad range; a high Q affects a narrow band. For bass room peaks, Q values around 2-4 are usually a practical starting point. The rule is to cut peaks, not boost dips. Boosting bass consumes headroom and can increase distortion while often failing to fix cancellation nulls.

The WiiM RTA can help identify the main peaks. It is not a lab measurement system, but it is good enough for coarse bass correction. The useful process is:

1. Play pink noise at normal listening level.
2. Measure from the main seat at ear height.
3. Look only at the broad 20-200 Hz behavior first.
4. Cut the largest peaks by a few dB.
5. Re-measure and stop when bass sounds calmer, not ruler-flat.

Small practical details

Several small setup questions came up. None of them replaces placement or PEQ, but they are worth getting right.

Speaker cable and contact quality

Normal bare speaker cable is fine. Strip around 8-10 mm, twist the strands tightly, insert the wire securely into the binding posts and tighten by hand. Avoid loose copper strands, and keep red-to-red and black-to-black polarity consistent. Extra cable length of a meter or two is not an audible problem with normal 2.5 mm² copper cable.

Desiccant packets

The small packets found in the speaker packaging are moisture-control or anti-mildew sachets. They are not part of the speaker. They can be reused in a small closet or drawer, but they saturate over time and should not be treated as permanent humidity control.

Vinyl stored in the stands

The matching Linton stands can hold records. Adding records increases stand mass, which can lower stand resonance and improve mechanical stability. At low listening levels the effect is subtle, but it is still a sensible, harmless use of the stands.

Burn-in

Mechanical settling may change bass compliance and subjective smoothness over the first tens of hours, but it should not be expected to transform the speaker's voicing. If a speaker is fundamentally too warm, too bright or poorly placed, burn-in will not fix that.

Final system logic

The most useful conclusion is not that one component is universally better. It is that the hierarchy of audible improvements depends on actual use.

For this system, at 60-65 dBA:

• The NAD C 325BEE is not being heavily stressed.
• The Chord Mojo is not an obvious bottleneck.
• The Super Linton is a better tonal match than a more analytical speaker for this listener.
• The main issue is room and boundary behavior.
• WiiM PEQ is the most efficient tool before buying more gear.

For someone who loved the HD600 and found the DALI Ikon 2 MK2 bright, the Super Linton is a coherent choice: full vocals, relaxed treble, useful low-volume body and enough scale for a large room. The KEF R3 Meta may measure and image better, but it is the riskier speaker if brightness sensitivity is the deciding factor.
