| Subwoofer suggestions for budget system? Keeping the bass out of the Maggies requires a subwoofer with a low-level high-pass filter that can be set to 60Hz. In turn, that requires line level cables to the sub and back to your power amp, adding complexity and expense to your system, as we... | |
| Which power cords have high resolutions and separation?? First, start with a dedicated 20Amp circuit with a whole house surge protector ($ varies) wired with 12 or 20 gauge wire and a Hospital Grade receptacles ($12 ea). Next get a good cheap oscilloscope off eBay or C-List and see if you've got any RF ... | |
| What selections do you play when showing off your system to others? I always let guests have the the first picks, the start working my faves into the mix. Usually I'll suggest Eva Cassidy, Aaron Neville, if it's Jazz, Charlie Haden and Pat Metheny "Beyond The Missouri Sky", Diana Krall. Eric Clapton and BB King "R... | |
| Is the seated-centered solo listening to music a dated tech? Multicell horns are used to reduce the level of early reflections in the listening space via tight control of their dispersion pattern. Most famously, the Altec 203B 'Long Throw' 2-Cell with a 20x40 degree pattern was 6dB hotter at 100 ft than oth... | |
| Streaming: WiFi or wired?? The lack of basic understanding of networking, hell, even basic physics is somewhere between amusing and appalling. Digital SQ begins with sample rate and bit depth. For a CD that's 44.1 KHz and 16 bits. 16 bits isn't adequate to avoid detail lo... | |
| Help Building an Audio Room I would try to net out a 13X 15 X 9 room. Sound transmission to the master suite indicates using not only a resilient clip system for the ceiling, and a layer of 1/2" plus a layer of 5/8" sheetrock. Fill the joist cavities with rock wool. Make sur... | |
| A Question About Time Alignment Hold on for one moment. Consider the piano. It's roughly 5 feet wide. So sound from a bass string is going to arrive at the mic way after sound from the treble side. Worse, that bass string is several feet long, so sound will arrive at different t... | |
| CD player suggestions... Putting a $600 Audiolab CDT-6000 through a $2500 DAC is 5X the specified budget. Go with the Marantz CD-6007. Not often noted, Marantz has two digital filter options, something not often seen outside separate DACs. It is the first CD player I've o... | |
| Router for Audio Streaming Destination Overload: Destination socket buffers can become full because of an application's inability to drain data from them in a timely fashion, potentially because of the server being overwhelmed. | |
| 60 Hz Noise Reduction 60zHz hum is always caused by either induction or a ground loop. If proper grounding resolves the issue, then there is no risk of introducing noise because there is no voltage differential. (See differential op-amp). An isolation transformer miti... | |
| HDMI send loud clipping and noise Change your cables and make sure they are firmly and completely sealed. Often HDMI cables are stiff and springy enough to dislodge themselves spontaneously from the mating connector. The result most often is exactly what you describe. | |
| Suggest one obsure album we all should hear Osamu Kitajima "Osamu". Not only Taiko drums that will test your cartridge and bottom your subwoofers, but you have Minnie Ripperton out-theremining a theremin on 'Yesterday and Karma'. Yes, that's a human voice you're hearing. You Tube it. | |
| Inherited a pair of JBL 4350 -- Need Advice Provenance matters with these speakers. What studio, what tours were they used with. E.G. Stevie Wonder used JBL 4350s for sidefill monitors in the Mid-70s (his were veneered). The utility cabinets and hanging hardware indicate pro use. If you can... | |
| Background noise. As someone who did acoustical consulting, this is a favorite topic. In particular, doing battle with architects an interior designers who rely on HVAC noise and in some cases ambient noise generation to create some sense of privacy in open office ... | |
| Preamps can color sound considerably. Surprising? Analog components have various nonlinearities that account for their signature contribution, subjectively negative or positive. Designers select from those components for desired effect and based on economics, availability, and personal biases. D... |
