AIX Records Dr. AIX's POSTS — 04 May 2015


I have my up days and my down days when it comes to thinking about high-resolution audio and place in it. The disappointment of not having been recognized by any of the mainstream or even lesser press following the AXPONA show has had an impact, no doubt. I watched a video of the AXPONA wrap up produced by Peter Breuninger. His partners on the panel were Myles Astor and David Robinson of Positive Feedback Online. Talk about depressing…these guys are all about analog tape and DSD. Peter believes the dramatic improvement in fidelity in the MBL room from one day to the next was due to a Synergistic Research’s HFT – High Frequency Transducer, which is nothing but snake oil. Don’t worry I’m not going to continue with my rant about analog tape and I can’t worry that these guys make pronouncements about audio fidelity without visiting all of the rooms…especially one that actually delivered real high-resolution audio content. Oh well.

This is an up day. I just received a call from a customer that made my day. Harvey actually called because he is experiencing problems playing several of the DVD discs he purchased at the AXPONA show. His setup is strictly stereo and includes an OPPO BDP-105, their top of the line player. He connects the two balanced XLR outputs from the OPPO to his preamplifier, amplifiers, and speakers. The video portion of the discs is displayed using the HDMI output from the OPPO directly to a new Samsung video monitor…not unlike the display I haul around to trade shows. But he couldn’t get any video to show up on the Samsung monitor. I assured him that the DVD-Video side of the disc should work fine on the system as he described. Harvey had already been in touch with the tech people at OPPO and they were stumped. That’s why he contacted me.

I explained that the stereo mixes are on the DVD-Video side of virtually all of my titles. I told him I would check the discs on my OPPO machines and get back to him. As I expected, everything worked out. The discs work fine. I suggested he try another DVD movie in his setup and sure enough that didn’t work either. It turned out that the Samsung monitor needed to have a menu setting adjusted. I’m thrilled that it was so easy.

During our conversation he related a brief story about my AIX Recordings. It turns out that he’s had caregivers assisting him with an illness in his family for over 5 years. While playing the Laurence Juber “Guitar Noir” DVD, one of them commented that she believed she was hearing a live trio playing in his listening room. She was astonished that it was a recording. Harvey’s comment was particularly interesting because he didn’t initiate the conversation or ask the woman about the music being played. She had heard music coming from his room many times in the past and never commented. However, the fidelity and realism of the LJ trio triggered a response. I loved hearing about this exchange. I’d be interested whether any of you have had something similar happen?

Gotta go…
