Denon DP-300F Review

Why this deck keeps coming up

Almost every discussion of turntables reaches the same fork: automatic decks are convenient and safe but have fixed arms you cannot adjust or upgrade; manual decks give you a counterweight and anti-skate but ask you to cue and lift by hand. Our own automatic vs manual guide lays that out, and then has to add a paragraph acknowledging the exception.

The DP-300F isthe exception. It is fully automatic — select the record size, press start, the arm does the rest and returns itself at the end — and it still has an adjustable counterweight, anti-skate and a standard-mount removable headshell. There is no long list of decks that do both. That is the whole reason to consider it and the whole reason it costs what it does.

What the mechanism costs and why the price is where it is

Automation on budget turntables is achieved by removing variables. A fixed arm mass and a factory tracking force let a simple cam-and-lever system driven off the platter do the work reliably. Add a counterweight and the arm’s effective mass becomes a user-set variable, and the mechanism has to cope with every position you might leave it in.

Denon’s answer is a heavier, more rigid platform: a die-cast aluminum chassis with a deliberately weighted base, which the manufacturer states is there to reduce vibration. That mass helps in two ways at once — it gives the automatic mechanism something stable to push against, and it does the plinth’s ordinary acoustic job of keeping speaker energy out of the cartridge.

The result is a deck that costs roughly two to three times a basic automatic. You are not paying for a better cartridge or a fancier platter. You are paying for the engineering that lets two normally-incompatible features coexist.

The removable headshell changes the upgrade maths

This is the feature most buyers underrate. A standard-mount removable headshell means the cartridge is not screwed directly into the arm tube: it is mounted on a small detachable carrier that twists off with a collar.

Three practical consequences:

• Cartridge changes take seconds, not an evening. Mount the new cartridge on a second headshell at the kitchen table, with good light and a protractor, then swap the whole assembly in one movement.
• You can own two cartridges. One for everyday records, one for your best pressings or for mono. Both stay aligned; you swap the shell. A spare headshell costs a fraction of a cartridge.
• Alignment is done off the deck.Aligning a cartridge inside a fixed headshell means working at an awkward angle over a plinth. This is the easier version of the same job — see how to set up a cartridge.

The cartridge it ships with is Denon’s own moving-magnet unit, pre-mounted. It is competent and it is not the reason to buy the deck. The reason is that replacing it with an AT-VM95E, Ortofon 2M Red or better is a genuine option rather than a theoretical one.

The automatic mechanism in daily use

Select 30 cm or 17 cm for a 12-inch or 7-inch record, press start, and the arm lifts, indexes to the correct lead-in position for that size, lowers and plays. At the end of the side it lifts, returns and switches the motor off.

Two things worth knowing. First, this removes the two commonest ways people damage records by hand: a dropped cue at the start and a stylus circling the run-out groove for an hour at the end. On a deck other people in the house use, or one within reach of children, that is a genuine safety feature rather than laziness.

Second, the automation does not take the manual controls away. There is still a cueing lever, so you can drop the arm mid-side on a specific track when you want to. Automatic here means “will do it for you”, not “will not let you”.

The preamp, and setting the switch correctly

The DP-300F has a built-in phono equalizer that can be switched out. Denon frames it exactly the way we would: use it to connect to an ordinary auxiliary input on a receiver or amplifier that has no phono socket, and switch it off if your receiver has a dedicated phono input.

That makes the deck a complete source on its own with powered speakers, and a clean source into a proper phono stage when you have one. The failure mode is the familiar one: two phono stages in series — the deck’s and the receiver’s — produces a loud, distorted, bass-heavy sound that people mistake for a fault. One stage in the chain, always. See phono vs line for the full explanation.

Setup and what you actually have to do

Out of the box it is close to a plug-in deck: platter, belt, mat, remove the stylus guard, level it, set the PHONO/LINE switch. The factory balance is correct for the fitted cartridge, so you can play a record immediately.

The setup work arrives when you change the cartridge, and then it is the standard procedure rather than anything Denon-specific: zero-balance the arm, dial the counterweight to the new cartridge’s published tracking force, set anti-skate to match, and check overhang with a protractor. Our tonearm balancing guide covers the arithmetic and the order.

One caution particular to automatic decks with adjustable arms: after changing cartridges, watch the first automatic cycle through. A cartridge that is significantly heavier or lighter than the original changes the arm’s behavior, and you want to see the arm land where it should before you walk away from it.

Who should buy it

Buy the DP-300F if automation is non-negotiable — a shared deck, a family room, a listener who will not do setup rituals — but you refuse to accept a cartridge you can never change. That specific combination has very few answers, and this is the best-known one.

Buy the AT-LP60X or the Sony PS-LX310BT instead if you want automatic operation and will genuinely never change the cartridge; both cost less and do that job well. Buy the Fluance RT81 instead if you are happy to cue by hand, because the same money buys more mechanical turntable when it is not paying for an automatic mechanism. The whole field is ranked in best turntables for the money.
