Short answer
Both are desktop DAC/amps, $285 against $449.
The Topping DX5 reaches 100 dB on 567 of the 567 models here, the Creative Sound Blaster X5 on 561.

Not published means the maker leaves it out, so that axis cannot be compared.

Only the Creative Sound Blaster X5 has a separate balanced rating from its maker; through it, it reaches 100 dB on 561 of the 567 models here. The Topping DX5 may still have a balanced socket — its spec sheet simply gives no figure for one, so there is nothing to put beside it. Derived figures are worked out from the loads the maker did publish.
| Load | Creative Sound Blaster X5 | Topping DX5 |
|---|---|---|
| 32 Ω | Derived | Published |
| 150 Ω | Published | Derived |
| 300 Ω | Derived | Published |
| 600 Ω | Published | Derived |
Both makers publish a power rating. Creative Sound Blaster X5 publishes at 150 Ω and at 600 Ω; Topping DX5 at 32 Ω and at 300 Ω. The other rows are worked out from those.
So the two columns are not equally firm row by row: at 150 Ω and at 600 Ω only the Creative Sound Blaster X5 figure is the maker’s own and at 32 Ω and at 300 Ω only the Topping DX5 figure is the maker’s own. On those rows the derived number is the one to doubt first.
6 headphones reach 100 dB on the Topping DX5 but not on the Creative Sound Blaster X5 — Moondrop COSMO, Moondrop PARA, Symphonium Crimson, 3 more.
15 headphones are left alone by the Topping DX5 under the one-eighth rule but coloured by the Creative Sound Blaster X5 (64 Audio Nio, 64 Audio Volur, Campfire Audio Andromeda 2023, 12 more).
561 of the 567 models here reach 100 dB on both.
Headroom is at a 100 dB SPL peak.
The widest gap on the list is the HiFiMAN HE400se: Topping DX5 has +22 dB of headroom there against +9 dB. 14 dB is about 23 times the power, which matters for peaks rather than for how loud the music sits.
The hiss columns are empty for Creative Sound Blaster X5 and Topping DX5 because neither maker publishes no output noise figure.

The Topping DX5 costs $164 more than the Creative Sound Blaster X5. Out of the 567 models here, that difference buys 6 more models driven to 100 dB and 15 more models left alone under the one-eighth rule.
Nothing runs the other way: there is no axis here on which the cheaper of the two does better.
Only published figures count here; blank axes are counted separately.
