| Finally, something new nulling is old news , but few know how to do it Nope, not doing that. :) | |
| Finally, something new PS - Any amplifier manufacturers who want to loan me a 2 channel amplifier, I promise to keep results confidential. Nothing over 60 lbs, please!! Same for preamps and DACs. | |
| Bits Are Bits, Right? Almost all this goes away with the use of a modern DAC. :) | |
| What does Roon make in SQ ( Sound Quality) when inserted in my system? I use Roon and I like it. No, I didn't really have any sort of magical sound changes. The UI and Tidal / ripped music integration was why I did it.Having said this, I was able to do a little room correction using the built in DSP capabilities. Oth... | |
| Doubting Sound Treatment ? In the commercial space I really like GIK - very high performance panels and traps, at a fraction of the cost of ASC. Conventional panel wise, yes. Anyone can totally replicate any GIK or other overpriced panel for peanuts. Yeah, but GIK is alrea... | |
| Speaker sensitivity, impedance, and calculating amp power "What role does impedance have, if any, alongside other factors in the calculation of how much power should be used to drive a speaker comfortably?" Zero, because in my experience, the math is not complete. We don’t get damping factor for the amp... | |
| Speaker sensitivity, impedance, and calculating amp power OP:If you are interested in theory alone, start with understanding power and sensitivity (not efficiency) at 1 meter. Assume the amplifier is a perfect voltage source, and the speaker an ideal 8 ohms. Then understand that you can use the power in ... | |
| Speaker sensitivity, impedance, and calculating amp power Honestly, as some one who does a lot of measuring and critical listening, this is difficult. It seems amps are more sensitive to speaker impedance than we think, so current is important, but the rated power at 8 Ohms is not really. Usually 50-100... | |
| OK...Added 2 HSU ULS-15Mk2 subwoofers To My System Big Hsu fan here. 😉 | |
| LP made from a digital master recording... The mastering engineer's vision of the finished product is a big deal. I wouldn't be surprised if he/she was making different choices for LPs. Certainly happens with different releases of CD's as well. | |
| Importance of phase and timing optimization when incorporating sub woofers ? What's funny is I literally just did this last week. I used the OmniMic DVD test to align the subwoofer to the center channel. My audio processor's distance setting was too coarse, so I got it as close as I could, and watched the frequency respon... | |
| What the 802 and 3 Decades can tell us about trends Wow you must have stayed up all night getting this thread done. @ebm If you are accusing me of being thoughtful before I post, guilty as charged. | |
| What the 802 and 3 Decades can tell us about trends One thing I've noted looking at these charts is how smooth the S3 tweeter was compared to the D varieties. I had always thought the ragged peaks were due to the micro motors, but this proves otherwise. Would be very interesting to look at compress... | |
| What the 802 and 3 Decades can tell us about trends I remember Dr. Leach bringing this up in a lecture. Not sure if he mentioned B&W specifically or if it was just a general discussion about electro-acoustical summing. All I mean to say is, that the bass alignment filters act far below where Tr... | |
| The new amplifiers is getting warmer and hot The Parasound A21 is A/B. I had the original, and they ran warm. I measured the wattage, and as I recall, the idle power was 2x spec. The other two I believe (but I am not Google) are class D. |
