I'm very sorry to hear about your mother. I lost my Mom 28 years ago, and I still miss her greatly to this day. I can relate to the pain of your loss, and you have my most sincere condolences.
Anyway, back to audio and AV SCIENCE
, which is what this forum is supposed to be about, I'm curious... do you ever do "blind" comparisons of cables when you make changes? Also, have you ever taken measurements of your system?
The reason I ask is because I once knew a guy who had a $200k+ system, with all kinds of uber-expensive cables, DAC's, cable lifts, custom built speakers, and components that had been heavily "modified" to improve sound quality. He invited me over to check out his system. I took along my collection of demo music, stuff I had heard on my own system, as well as many other systems, and knew intimately. After just one song, it was apparent that I was not hearing notes I was used to hearing, and hearing other notes more pronounced than I was used to. I didn't say anything to him, but I asked if he minded if I took some measurements. He didn't seem enthusiastic, but he agreed.
So, a few days later, I went back with my measurement gear and this is what I found:
This confirmed what I was hearing. A deep recession below 40 Hz, where his subs were *supposed* to have excellent output, a big 12 dB peak at 40 Hz, a wide, deep 12 dB trough from 65 to 100 Hz, and another wide, 10 dB peak from 100 to 175 Hz. Overall, his system was +/- 12 dB from 20 to 300 Hz. I showed him the measurements and explained what they meant, and the effect of room modes on the response. I also explained what to do to fix these issues.
- Move the subs
- Move the seating
- Run Room Correction
He was unwilling to move anything in his room, but he did let me run Audyssey, (which was still available in his heavily modified Onkyo pre/pro.) So I ran Audyssey and got the following:
Still not what I would consider "great" response, but "greatly improved"... it was now +/- ~6.5 dB. For reference, this is how my own system measures, and what I would consider "great" response:
After running Audyssey on his system, we re-listened to some of my demo material and it sounded "better" to my ears. However, the owner didn't like it nearly as much as his pre-Audyssey sound, and we ended up turning it off. I suspect he had gotten so acclimated to hearing that 40 Hz peak, that when it was taken away, he missed it. Same for the other broad peak above 100 Hz. (Or... he was so predisposed to believe that room correction was "bad" (as most "audiophiles"
do), that he subconsciously, or maybe even consciously, decided in advance that he wasn't going to like it, no matter what.) Either way, we shut off Audyssey and he was once again a happy camper, satisfied that he was getting everything he paid for from his $200k+ system.
So... I'm curious if you have ever measured your system, and if so, what you found. Thanks!
