Wow, so maybe high-passing help puts them in the same space, because it's removing the sub-harmonic room reflections from the clarinet.

I've mixed this some more - EQing the clarinet's fundamental out of the guitar part, and tweaking the verb, adding a panned delay to the clarinet (which I also send to the verb). So is this better?

Code:
foo_abx 2.0.2 report
foobar2000 v1.3.16

File A: 15tq time aligned.wav
SHA1: 331d3690d3f7a591f0162e43b844cf76502222f4
Gain adjustment: -1.63 dB
File B: 14Z3_mp3.mp3
SHA1: b9c6af9571aeed641773e48b7e6ab3ccf312a6b3
Gain adjustment: -5.01 dB

Output:
WASAPI (push) : Speakers (Creative SB X-Fi), 24-bit
Crossfading: NO

This file starts earlier than the other two you uploaded, so I decoded it and time-aligned it with another file, otherwise I can't blind test them. Also, this file is quieter than your previous files, so I loudness matched (R128 algorithm) them before testing, you can see the adjustment in the ABX log.

Loudness matching is very important for a reliable listening test, as Ian Shepherd demonstrated:

I mainly focused on the spatial relationship between guitar and clarinet. Now both 15tQ and 14Z3 also sounded like two instruments are played in the same space, but in 15tQ, the clarinet seemed more away from the mic, as a result, it made me feel that the room of 15tQ is larger.

Couldn't say which one is better, it depends on where do you want to place your virtual mic.

Anyway, it is more important that you, the mixing engineer can hear the difference and make an decision based on your preference.
