Esoteric X-01 Limited or Esoteric P-05/D-05 combo?

Thanks to everyone, but the question remains the same - Has anyone heard P5/D5 and X-01 Limited during A/B comparison? And what were the results?

Mkilpi, I'm actually interested in playing red book CD mostly, so X-01 Limited and X-01 D2 are completely the same in that regard (RBCD), correct me if I'm wrong. The differences are all about SACD playback (X-01 D2 doesn't convert DSD to PCM before D/A conversion). So please can you describe the differences between the two players that you've heard? And have you heard the P5/D5 combo?

What are the AES/EBU cables that you've compared to the IEEE 1394 connection?

I have D5 being connected to my CEC 51XR (acting as a transport) via Audioquest Raven AES/EBU. The sound quality is just outstanding. Will P5 outperform CEC, I wonder? If so, I would consider P5, but there's a question of connection options.

It's hard to imagine that stock iLink cable can outperform an expensive Dual-AES solution.
