Both are portable players, $1599 against $1699. This page puts them side by side on the only three things a maker can be held to — power, output impedance and noise — and then asks the question that actually matters: which headphones do they treat differently?
The iBasso DX340 reaches 100 dB on 566 of the 567 models here, the iBasso DX320 on 565.

| Output impedance | 0.34 Ω | not published |

| Headphones it reaches 100 dB on out of 567 | 565 | 566 |
A figure marked not published is missing from the maker’s own material, which is not the same as being good or bad. Where one of these two publishes a number and the other does not, the comparison on that axis cannot be made at all — and saying so is more useful than guessing.
1 headphone reaches 100 dB on the iBasso DX340 but not on the iBasso DX320 — Moondrop PARA.
565 of the 567 models here reach 100 dB on both. That is a power count and nothing more; whether either source suits a given headphone also depends on the two lines above.
Each has a page of its own with every power figure traced to what the maker published and a full headphone list: iBasso DX320 and iBasso DX340. Or put either against your own headphones in the source comparison tool.
