Some will say it is foolish for you to use the same ICs, Speaker wire etc from the same cable line others will say mix and match.
For me I did the reverse of what you are suggesting right now. I have the DH Labs IC equivalent of the T-14 wire and am using the Q10 speaker wires. The sound is more full and I have no issues with the highs.
In another tube based system I've used DH-Labs T-14 speaker cables with Monster I400 ICs and the sound was a bit dull and clinical.
Sorry this isn't a direct comparison but if I was in your shoes and had the Air Matrix ICs I'd also go for the Q-10 speaker cables. I've handled both the Q10 speaker cables and T-14 and the Q10s felt much more substantial.
