| Who is planning to buy the oppo-95 and...? Admranger,I assume your Rotel receiver doesn't handle HDMI, otherwise a single HDMI cable would seem preferable to six analog RCAs for 5.1, especially given your 80/20 movie bias. If you don't care about lossless codecs, can't you use a single RCA... | |
| Hearing loss Temporary or more permanent? Re A & C weighting: A-weighting is contoured to replicate the hearing sensitivity data of Fletcher and Munson; C-weighting is essentially flat. So you might use the A scale to estimate how loud a sound is and the C scale to determine its level... | |
| Is One Subwoofer Really Not Appropriate For 2-Chnl I got carried away in a dialog that really was off topic. Sorry.db | |
| Is One Subwoofer Really Not Appropriate For 2-Chnl Bryon.One of the most reliable phenomena in psychoacoustics is what Is know as the masking level difference (MLD). Present a mid-freuquncy sinusoid in correlated noise to both ears and adjust the level until it becomes inaudible; flip the phase of... | |
| Is One Subwoofer Really Not Appropriate For 2-Chnl Bryon,I quit following the literature around 1970. I was an admirer of the Jeffries model of binaural processing, but a study I did using computer generated signals and narrow bands of noise was inconclusive about the phase relationships of the si... | |
| Is One Subwoofer Really Not Appropriate For 2-Chnl Bryon,It's been decades since I did research in binaural processing, but I wondered why someone from a university in South Carolina would publish such an article in other than JASA. Some of the contentions about levels of neural processing of temp... | |
| Kef Kube equalizer Unsound & Klipschking, The KEF museum claims the 103/4 has useful LF to 50 Hz, so setting the crossover to a sub at 60 Hz might seem prudent, although I doubt 80 Hz is too high for most high quality subs. I've tried both with my 104/2s, and no... | |
| Hearing loss Temporary or more permanent? Bifwynne, as a general rule if it feels comfortable to you it's probably OK. If you think you're pushing it, turn the level down a bit. You might start by finding a level where soft jazz (e.g. Bill Evans), Bach, and Mozart feel right, then look at... | |
| Hearing loss Temporary or more permanent? Bifwynne, I knew some of the people who were on the scientific committees that made the recommendations to OSHA.Stevecham, I think you're doing the right thing by keeping peaks lower, but you need to know neither the auditory system nor other neur... | |
| Kef Kube equalizer I have a pair of KEF 104.2s, four 102.2s, and four 102s. I don't use my KUBEs with any of them. Instead, I use two Velodyne HGS-15s with the 104.2s and 102s (2.1 & 5.1) and an HGS-10 with the stacked 102.2s (2.1). Cross over to the sub at 80 H... | |
| Hearing loss Temporary or more permanent? One caveat when using the OSHA guidelines is the lobbying that goes into setting them. It costs money to make the workplace quieter. I'd be inclined to use a few dB under the guidelines or to shorten my exposure time. I attended a gathering of aud... | |
| Hearing loss Temporary or more permanent? When I was a grad student decades ago, I worked at a research center aimed at the study of noise-induced hearing loss. Temporary threshold shift (TTS) was a hot topic. Rock concerts were in vogue, and lots of folks were concerned about whether the... | |
| Soundstage, Imaging, Detail & Presence?? Sebrof, in rereading my previous post I realize my verbiage was a bit confusing. What I had intended to convey is that there seems to be two camps. What I might call the the analog camp favors tubes and vinyl; the digital camp, along with those wh... | |
| VTI audio rack, any good? You just unscrew the top of each leg, pour in sand or shot, and screw the top back on. Simple as that. In my 6/10/10 post, I should have mentioned that the custom made spikes cost more than the rack. I recently added Sorbothane pads under the feet... | |
| Soundstage, Imaging, Detail & Presence?? I suspect the speakers and acoustic environment of the room have far more to do with presence than tubes v. solid state. I've often wondered how fundamentalism survives scientific explanation, but the controversy over analog v. digital whether it ... |
