Audiotruth Opal v Analysis plus Copper oval IC

I picked up a pair of AQs Audiotruth Opal ICs recently and am impressed by them. I used Cardas neutral reference for many years then switched to Anlysis Plus Yellow and black Copper oval. The AP had a blacker background and was warmer with a bigger stage but did not seem as clear almst a grundge to it, but the stage was less congested then the NR Have always had AP oval 9 speaker wire.

Now I am comparing the Opal IC to the AP copper oval and the Opal seems to have more HF extention, sounds cleaner and has a bigger stage.
Has anyone had any experience with the AQ Audiotruth Opal???? Thoughts?? Thanks,Keith
