Audio-Technica builds the phono stage in across its whole current range, and every deck this site covers publishes it: AT-LP60X (“yes — switchable”), AT-LP70X (“yes — switchable”), AT-LP120XUSB (“yes — switchable”), AT-LP120XBT-USB and AT-LP5X (“switchable phono/line output”). So unlike a Fluance RT85, an AT deck is never silent for want of a preamp.
What the switch actually does is choose between two signal paths: PHONO sends the cartridge’s raw few millivolts out untouched, for a receiver or an external stage to handle; LINE routes it through the deck’s own amplification and RIAA equalization first. The rule that governs everything below is that exactly one phono stage belongs in the chain. Buy an external preamp and the switch goes to PHONO. Leave it on LINE and the external box is amplifying an already-amplified signal, which sounds loud, harsh and wrong.
Three things make the external box worth buying: a noise floor lower than a circuit sharing a chassis with a motor, gain you can match to the cartridge, and loading you can set once you have fitted something better than the stock stylus. If none of those describe you, keep the switch on LINE and spend the money on records.
Which Audio-Technica do you have?
| Deck | Fitted cartridge | Built-in preamp | Is an external stage worth it? |
|---|
| AT-LP60X / AT-LP60XBT | AT3600L, conical, replaceable stylus only | Yes — switchable | Rarely. The fixed arm and conical stylus limit it first |
| AT-LP70X | AT-VM95C (conical, VM95 body) | Yes — switchable | After a VM95E or VM95ML stylus, yes |
| AT-LP120XUSB | AT-VM95E (elliptical, 4.0 mV) | Yes — switchable | Yes — the clearest case on this list |
| AT-LP120XBT-USB | AT-VM95E (elliptical) | Yes — switchable | Yes, for the wired path; Bluetooth out bypasses the question |
| AT-LP5X | AT-VM95E on a removable AT-HS6 headshell | Yes — switchable phono/line | Yes, and the headshell makes the cartridge upgrade easy too |
The pattern is that the external stage earns its place from the AT-LP70X upward, because those decks use the VM95 cartridge body: the stylus can be upgraded from conical to elliptical to micro-linear without remounting anything, and each rung resolves more than the deck’s internal circuit comfortably shows. On an AT-LP60X the limiting part is the fixed tonearm and the conical tip, and no preamp fixes either.
Matching the stage to a VM95 cartridge
- Moving magnet is all you need. The VM95 series is a dual moving-magnet design and the AT3600L is moving magnet too, so an MM-only stage like the PA10 or the DJ PRE II is a correct match rather than a compromise. The MM/MC picks here are bought for their adjustability.
- Gain against a 4 mV output.Audio-Technica publishes 4.0 mV for the AT-VM95E, which is a healthy moving-magnet level — but a fixed low-gain stage into a quiet amplifier still leaves you playing records at three-quarters volume. The Fosi Box X2 switches between 39, 42 and 45 dB and the DJ PRE II has a gain control, which is the cheapest cure for that.
- Loading, once you fit a better stylus. The Pro-Ject Phono Box is the only pick with adjustable loading. That is the pick to buy alongside an AT-VMN95ML stylus or an Ortofon 2M, where the manufacturer publishes a load the stage has to meet.
- A headphone output, if the deck lives on a desk. An AT-LP120XUSB next to a computer is the commonest setup on this list, and a phono stage with no headphone jack means buying a second box to listen privately. The Douk Audio T4 PRO has one rated for 32 to 300 ohm headphones, which is why it is here rather than on specification alone.
- USB is a separate path.The AT-LP120XUSB’s USB output carries its own converted signal to a computer and does not go through an external preamp at all. If you are digitizing records, the preamp choice does not touch that route — our recording guide covers it.
How to switch over without breaking anything
Set the deck’s rear switch to PHONO. Run the deck’s RCA cables into the preamp’s input, the preamp’s output into any line input on your amplifier or powered speakers, and move the ground wirefrom wherever it currently lands onto the preamp’s ground post — the earth belongs on whichever box holds the phono stage. Start the volume low: you have just added 40-odd decibels of gain to the chain.
If it hums after the swap, that is the ground wire and not the box: hum and grounding works through it in order. If it is quiet and thin, the switch is still on PHONO with nothing amplifying it, or on LINE into a PHONO input. And if you want the whole field rather than the Audio-Technica-shaped slice of it, our phono preamp roundup and picks under $100 rank everything we cover. Fluance owners should start at the Fluance version of this page instead, because on an RT82 and above the stage is mandatory rather than optional.
