| Integrated stopped working Perhaps "trigger circuit" doesn't work. Either something is connected but not driving, or something is connected by mistake, like 3.5mm headphone jack. | |
| Class A 30 Watt Amps: Are they enough to drive my book shelfs? @almarg Yes, loss will be 6.54dB, but from rated sensitivity of one speaker it will be only 3.54dB. For 2m listening distance, that they likely assumed as an average, there will be no error. Sound level at listening position will be the same as ... | |
| Class A 30 Watt Amps: Are they enough to drive my book shelfs? @almarg Al, I agree, but shouldn't second speaker make a difference (both at 10' distance)? Two speakers vs. one should add +3dB making overall error 3.54dB (no error at 2m listening distance) | |
| Class A 30 Watt Amps: Are they enough to drive my book shelfs? @almarg Al, remember that there are two speakers, not one (+3dB). Room gain adds +3dB (or more) and I'm sitting at about 3m from the speakers equal to loss of a little more than 6dB (9.5dB?). Rule of thumb has -3.5dB error here, but works pe... | |
| Stability analysis @rathi I used many versions of SPICE simulation, including PSPICE. ALTIUM SPICE and LTSPICE. All of them are built on the same Berkley SPICE and only user interface is different. PSPICE was the best of them, when it was still available. I used (Wi... | |
| Class A 30 Watt Amps: Are they enough to drive my book shelfs? @almarg For a non-planar non-line source speaker, especially a relatively small bookshelf speaker, putting aside the effects of room reflections SPL will fall off at 6 db per doubling of distance. Al, yes but doesn't it apply to open space or anec... | |
| Class A 30 Watt Amps: Are they enough to drive my book shelfs? For your 8 ohm speakers efficiency=sensitivity. Driven by 1W they will deliver 86dB sound level. 30W (30:1 ratio) should give you about 15dB more resulting in 101dB. It should cover even symphony orchestra (EU directive limits level to 85dB in ... | |
| Daedalus Ulysses I'm pretty sure Almarg has them. | |
| BASH and expired patents @roberjerman: I found this in "The Poor Audiophile": The feed-forward error correction of THX’s AAA™ technology keeps the AHB2 nearly distortion free when driving a heavy load. As noted in our interview with audio legend Laurie Fincham, THX’s Se... | |
| BASH and expired patents Basically.....BASH is a class AB or C-ish output stage, combined with a pulsed power supply, where the rail voltages dynamically shift in level, in conjunction with the signal.Class H appears to be exactly that - class AB output with modulated pow... | |
| Is Class D Analog or Digital ? Words "switching" and "analog" in the same sentence might be confusing, since switching between two voltage levels suggests "digital" operation, but at this point voltage is not the quantity of interest - "duty cycle" (average value) of the square... | |
| dBpoweramp with iMac I just opened (free) XLD, that I use on the Mac and it required update to work with Catalina on my computer. I installed update and it seems to be working. Chances are dBpoweramp requires some update (website doesn't list one yet). Catalina is ... | |
| CD distortion through preamp @tripg I glanced over manual and found warning, that mkII uses different tubes than mkI. Are you sure you have 6H30 tubes installed?Manual say that single ended inputs can handle up to 14V (28V for balanced) at the lowest gain position (6dB). ... | |
| Ethernet Cable or Not? In either case Wi-Fi or Ethernet you deliver exactly the same data. Wi-Fi might have advantage here, separating electrically noisy computer from the DAC, but the question is what happens with the received Wi-Fi data? When your receiver converts ... | |
| Alternatives Software for iTunes on Mac @joscow Sorry to hear that. I have I tunes Version 12.9.5.5 running on late 2014 MacMini with Mojave Version 10.14.6 and have zero problems. I changed library, but it was long time ago. There is Itunes media location (Preferences => Advance... |
