You would still be double-amping as any signal from the headphone jack has passed through the Clip's amplifier. It is a clean enough signal that you should still realize benefits from using an external amp to gain added output power. Don't worry about double-amping. It is often considered a negative practice by some, but given a clean output signal from the headphone amplifier, it can prove to be an asset when needed for hard-to-drive phones or for additional headroom for transient peaks.
To get the best performance, you should use good quality music files, such as .wav or .flac. If you are using MP3 files, the best results are with 256 or 320 kbps rips.
