Choosing between these turntables & record players starts with a practical question: do you want a parts project with clearly named USB and RCA connectivity, or a repair centered on one specific Denon DJ model? Both are explicitly sold for parts or not working, so the useful distinction is not plug-and-play convenience. It is whether the Numark TTUSB's listed features fit your repair plan better than the Denon DN-S3500's model-specific identity.
Quick verdict
The Numark TTUSB is the stronger match for a project that needs listed RCA, USB Out, a built-in phono preamp, or pitch control. The Denon makes more sense when the exact DN-S3500 model is the deciding requirement. Neither should be treated as a ready-to-use record player: both carry a parts or repair condition.
Price and attribute comparison
| Product | Listed price | Condition | Distinct listed detail |
|---|---|---|---|
| Numark TTUSB DJ Turntable | USD 49.99 | For parts or not working | Belt Drive; Silver |
| Denon DN-S3500 DJ Turntable | USD 64.99 | For parts or not working | DJ Turntable; 1-Channel |
The listed-price spread is $15, with the Numark at the lower figure. That difference matters most when both repair directions are acceptable and the Numark's named features fit the project.
Where each product wins
Numark TTUSB DJ Turntable

The Numark wins for a repair plan built around clearly named connections and controls. Its description also names a 45 adapter and USB cable, giving the project a more concrete accessory starting point. The $15 lower listed price is another reason to favor it when those inclusions and the feature list align with the intended setup. This is still a parts-or-repair purchase, so the advantage is about the project's listed scope rather than a claim about working performance.
Denon DN-S3500 DJ Turntable

The Denon wins when matching a particular DJ unit matters more than having a broader set of named connections. Its model-specific identity gives it a clear role in a repair project built around that unit. The trade-off is the higher listed price and the same parts-only condition. The description says no box or anything else is included, while power cables and other accessories are not included unless listed. There is also no manufacturer warranty. Its reason to choose is specificity, not an assertion of ordinary playback readiness.
Product notes
Numark TTUSB DJ Turntable
The Numark is worth choosing when the included 45 adapter and USB cable suit the repair project. Its description also identifies a cartridge with cover, although it says the needle may not still be connected. That is the key limitation alongside the as-is, parts-or-repair condition: testing reached only the point that the turntable powered on. The named accessories help define what the project includes, but they do not establish playback readiness. The silver color is also identified, which may matter for a matching setup. Pick the TTUSB for its concrete accessory list and lower entry price, while accepting that the needle and broader operation remain part of the repair question.
Denon DN-S3500 DJ Turntable
The Denon fits a repair centered on the DN-S3500. Its limitation is explicit: the unit is described as broken and for parts only, and the attributes state that it has no manufacturer warranty. The description also says no box or anything else is included, with power cables and other accessories not included unless listed. That makes the included-item scope a practical constraint for the project. Choose the Denon when matching the named model matters enough to accept the parts-only condition and the USD 64.99 listed price. It is a specific repair candidate, not a basis for claiming ordinary working playback.
Final choice by use case
- Choose Numark TTUSB DJ Turntable when the project needs its listed RCA, USB Out, built-in phono preamp, or pitch-control features.
- Choose Denon DN-S3500 DJ Turntable when the exact model identity and 1-channel specification are the deciding requirements.
- If both paths are acceptable, favor the Numark for a feature-led repair and the Denon for a model-led repair. The right choice is the one whose listed attributes match the work you intend to undertake.
