Curated Listening Chains

This is where people go wrong most often, and it is also the only place where a figure has to be respected rather than an opinion.

A tonearm has an effective mass; a cartridge has a compliance, meaning how readily the stylus suspension flexes. Together they form a system that resonates at a particular frequency, and that frequency needs to fall between 8 and 12 Hz. Drop below and you are in the territory of record warps and structural vibration: the arm starts to wobble on dished records and the bass swells. Climb above and the resonance edges into the lowest audible band, thinning or colouring the bass.

The practical consequence is counter-intuitive: an expensive cartridge on the wrong arm sounds worse than a cheap one on the right arm. A very compliant cartridge wants a light arm; a stiff one wants more mass. It is not a question of how much you spent but of what pair you have formed.

The most instructive case is the Thorens TP16. In its original form the arm has an effective mass of around 16.5 grams; from the MkII onwards that drops to roughly 7.5 grams — and an intermediate version exists as well. Same name on the arm, two very different objects: a high-compliance cartridge that sings on the MkII can be the wrong choice on the original. Anyone buying a used TD 160 often does not know which version is coming until it is in their hands, which is why the question has recurred on specialist forums for twenty years. That is precisely why here the rule matters more than the product name: the name changes meaning, the rule does not.

The second constraint arrives from the far end of the chain. A loudspeaker's sensitivity tells you how much sound pressure it produces for a given input, and the scale is logarithmic: three decibels less means twice the power for the same volume. An 86 dB speaker asks twice as much of an amplifier as an 89 dB one. So before looking at an amplifier's wattage, look at the sensitivity and impedance of the speakers: they set the demand.

That said, rated watts tell you far less than they appear to. The two historic budget rivals of the 1980s — the NAD 3020 and the Rotel RA-820 — are famous for exactly this. The NAD is documented as having around 3 dB of dynamic headroom, delivering well beyond its nominal twenty watts in short bursts, and at its American launch it was put in front of a 1.1-ohm load without folding. Of the Rotel, which depending on version is rated between twenty-five and thirty watts, a long-term owner writes that these amplifiers go well past their rated power on peaks, with plenty of headroom.

But headroom is not magic, and that deserves saying too: another owner documents the same Rotel struggling badly with a pair of Celestion SL6s, speakers with a reputation for being power-hungry. Taken together the two accounts give the whole truth. Dynamic reserve saves you on peaks; it does not excuse you from doing the sensitivity arithmetic. The catalogue figure on its own predicts nothing; sensitivity paired with behaviour into the load predicts a great deal.

Every component has a character, and characters add up. Two excellent components sharing a flaw will double it. Bright, analytical electronics with equally bright speakers make a system that impresses for ten minutes and tires by the third record; the same electronics with warmer speakers find a balance. It is not a law of physics, but it is why successful pairings resemble each other so little.

One documented example, and I will attribute it: a reviewer who owned both describes buying a Sugden A21a — the English pure Class A integrated — while already living with a pair of ProAcs, and found the combination strikingly close to the tube amplifier and ProAc pairing he had enjoyed before: a warm tone, a highly musical sound. It is a synergy frequently reported for this combination.

And then, immediately, the honest counterweight: synergy belongs to models, not to brands. In the same discussion spaces another owner finds the ProAc Studio 140 too bright on jazz with a Sugden in front of it — and What Hi-Fi's own review of that speaker warns that aggressive recordings or an already bright system will draw attention to its tweeter. Same amplifier brand, same speaker brand, opposite outcome.

Two rules follow: choose complementary characters, and distrust synergies stated at brand level. Underneath a brand sit models with different balances.

There are two schools here, and it is worth knowing both rather than adopting one on faith.

The first is the heavy front end: turntable and cartridge take the large share, because the signal is born there. The argument is hard to dismantle — whatever the stylus fails to retrieve from the groove, no amplifier or speaker downstream can put back. A split that recurs among used-market buyers puts roughly half the budget into turntable and cartridge, dividing the rest between amplification and speakers.

The second school is the balanced split, and it carries a serious objection: the loudspeaker is the component that interacts with the room, and it is the one you will notice first if it is wrong. A magnificent front end in a bad room with the wrong speakers will never deliver what it promises.

On the used market, though, the first school is the more commonly recommended, for a practical reason: the source is where second-hand money goes furthest, because well-built turntables and arms age gracefully and their prices have fallen, whereas loudspeakers are the component where inexpensive new designs have improved most in recent years. Take it as a rule of thumb born of experience rather than a law — the room can overturn it.

The reason this strand looks at the second-hand market is arithmetic: for the same budget you move up a class. Fifteen hundred euros of used equipment brings home machines that would cost a great deal more new, from a tier where construction — chassis, arms, transformers — was a cost item rather than a styling decision.

The drawback is equally plain, and experienced buyers repeat it: buying without hearing is a gamble. Add to that the line that settles many sums, namely the condition of the machine and any service it needs. All of that lives in our guide to restoring vintage hi-fi, and it is the piece to read before answering any advert. The short version: used is worth it when you can verify — by listening, or by buying from someone who documents what has been done.

From these criteria come three systems, each with its own budget and its own logic.

~€800, entirely used. The system for someone starting properly: an honest, well-matched source, amplification with a built-in phono stage, speakers that are easy to drive. Rule two governs here: with modest power you choose sensitive speakers, not the other way round.

~€1,500. The band where the heavy front end pays best: the step up in source quality is audible, and the amplification can stay simple without holding anything back.

~€3,000. Here all three rules work together and the margin for error narrows: at this level a wrong pairing costs more than a better component gains.

Each system starts from these criteria and applies them to real machines — and each comes back here, because the method does not need writing three times.
