  1. Yes, it's quite a rabbit hole with an amazing sound system 🐇
  2. https://clinicaltrials.gov/ct2/show/results/NCT03808389 Makes intuitive sense that this symbiosis we have with gut flora isn't only for digestion but maybe it's just the microbes influencing my thoughts 😁 That's what my gut tells me anyway...
  3. An artist / group doesn't have to be hugely popular or have many release versions/masterings to have a variability of dynamic quality apparently. I was very surprised to look up a recent favorite for dynamic recording of real instruments - Gordon Goodwin's Big Phat Band - XXL. Its rating was very disappointing in http://dr.loudness-war.info/album/list?artist=goodwin&album=xxl until I found my DVD-A version which has a hugely higher dynamic range rating. Now maybe some of this is rater variability but I have to get the CD version now just out of curiosity to see if the dynamics are really that different (crushed) on the CD vs DVD-A This Metallica mentioned earlier doesn't rate that good but maybe I'll get it too to hear for myself...
  4. On the Campbell quote, maybe I need to read a bit more of his writing to understand his viewpoint, but, I immediately find myself wondering if for Campbell and his friend "the best things" ARE the best BECAUSE they transcend thought. That "things" (experiences) which challenge our ability to think about them, which can't easily be encoded in thought or word are by that definition "better" or "best" BECAUSE they challenge us to expand our thinking about them and expand our communicating about them. I put on my copy of Fear of A Blank Planet DVD-A and immediately thought I heard the "harshness" you speak of. A question is how much harshness, aggressiveness, and distortion is intentional, especially if the recording is being mixed and mastered on playback systems that aren't flat amplitude/phase response? This is particularly interesting in this case where you have Steven Wilson having so much creative control from writing to playing to mixing to mastering of FoABP and his many other stereo and surround creations. More that most other musicians, SW may have a more fully controlled and realized intent for the listener. Are we straying from his intent for our listening experience by eliminating distortions that were present during the mixing/mastering? Perhaps I'm being a bit insincere on that line of argument. Ultimately, we can't know exactly the creator's intention for our listening experience. Also, one person's unpleasant harshness is another's exhilarating aggressiveness. Personally I love PT and Steven Wilson's music and want to enjoy listening not have to "steel" myself against it. So, I'll continue to follow you down the road of flat amplitude/phase response horn loaded systems since at bottom - it sounds better to me. What can be said of "subconscious auditory effects"? Not much unless we invoke words about the inadequacy of words - such as "ineffable" or notice the indirect evidence as you have observed - I find myself listening more and with better attention and enjoyment.
  5. What did you change that made it better? By "serial numbers" being off do you mean that 1 top section was paired with the other bass bin? Wouldn't think that would make much difference. I got good bass pretty quickly when I first got Khorns. I guess I think that it is us that does much of the "breaking in" especially if you're not used to horn loaded bass as I was not. That being said, the quality and when called upon - quantity of bass with my active K402/Khorn blend tuned to my room is unsurpassed in my experience. And that's with only one real good corner.
  6. I suspect you’re still testing, but, can you begin to say what it is about those other horns that’s got you thinking you’ll sell the K402s?
  7. So that's what we're doing! All I know is it sounds great. What effect does it have on the Jube bass bin to obstruct the top of the mouth somewhat with the lowered K402? I'll definitely be working on adding damping panels on my mongrel lowered K402/TAD 4002/Khorn bass setup.
  8. Haven't critically listened to them yet. I've got one driving the bass in my center channel Chris and I have been attempting to tune.
  9. Got 2nd monoblock built up and playing. I'll be comparing them to Trends TA 10.2 class T, VTL Tiny Triode PP tube monoblocks and First Watt SIT2.
  10. I received a pair of Hypex Nc400 monoblock kits last week. Built one up easily except a wire on the input cable harness detached so I used the harness from the other kit and it worked. I'll re-solder the first input cable and build up the other kit then try them doing different jobs in my systems (bass, treble, full range) and report after a while. Initial impression is that they're very well made.
  11. Interesting white paper from the makers of one of the better Class D amp modules: https://www.hypex.nl/img/upload/doc/an_wp/AN_UcD_and_IMD_DIM_slewrate.pdf My take-away for non class D amps: "An amplifier with moderate slew rate that remains perfectly linear until it actually slew limits is a much better amplifier than one with a huge slew rate that starts distorting much earlier" And for class D "Slew rate in class D amplifiers is completely unrelated to that found in linear amplifiers. The input stage is a comparator with the 400kHz carrier at its input. The "slew rate" is limited by the output filter. Apply a voltage step from -Vcc to +Vcc to the output filter and look at the output. The bandwidth limiting action of the filter necessarily limits the dV/dt found there. That doesn't mean that the filter or anything else has gone non-linear. It's just that the bandwidth is limited, nothing more, nothing less. Slew rate in a class D amplifier is a completely linear effect. Here, power bandwidth equals small signal bandwidth by definition, because there is no non-linear effect involved."
  12. This has been a fascinating topic for me for years I realize without really pursuing it. While I don’t doubt that your long and varied experience is very real Mark, I must wonder if there is any electro/mechanical/acoustic reason WHY it might sound better to have amounts of power we Absolutely Never use? ignore this please if too much of a sidetrack
  13. Recently experimenting with a K402 in the fireplace for dialogue in movies/TV, 2.0 and 2.1 using a summed setting in the Xilica 4080, DTS neo6 etc. from my older prepro (Nuforce AVP16) and true 5.1 SACD, DVD-A, and Blu-ray. Thanks for the links to PWKs writing sixspeed. I note he recommends a relatively close match of efficiency between center speaker and the flanking L and R. I have that with matching k402s in mids and treble but not bass. A couple small DR woofers are no match for the KHorn bass bins but I’ll measure and adjust with REW and Xconsole to see what I can hear.
  14. The other enjoyable sensation is one of pressure. The feeling of pressure waves, of the room being pressurized. My 10" sub rolling off below 40Hz does it in the close confines of the car but in the HT? DTS10! There's something primal and thrilling/scary about those sensations - perhaps imprinted in our genes from thousands of years of such natural occurences - waterfalls, ocean waves, migrating herds of beasts, and of course thunder storms!
