| Good source for NOS tubes in SF Ba y Area? Most of the brick and mortar electronic stores have closed up since mail order is so competitive. As an EE, I do miss the real stores where I can touch and feel things. I use this place now: https://www.tubedepot.com/ They have a lot of cho... | |
| Toto Tungsten Speaker Cables by Bogdan Tungston? It's Interesting as to why anyone would use a material that has such a poor conductivity rating i.e. compared to copper or silver, to make cables. That was my thought, curious indeed. | |
| Which amp will cause a larger increase in electric bill? The Kill A Watt meter is ideal for things like freezers or refrigerators. These items vary their power consumption on whether their compressor is running, how often the door is opened, and what the ambient temperature happens to be. For amplifi... | |
| Toto Tungsten Speaker Cables by Bogdan I haven't heard them but are they really made from tungsten wire? | |
| Increase total Speaker Impedance -- Potential Solution Yes, sort of; clearly, a definite maybe. :-) What you need to do is buy two more speakers identical to what you currently have, and wire them in series. That would do it. The reason one cannot put another 4 ohm driver in series with it is t... | |
| Class D vs Class AB - Looking for best used budget amplifier for Magnepan MG12 This is an interesting question. I have had a Marantz four channel Class D 450W amp on the four subs in my system for some years now. I often wonder if the sound would be better with a good quality 250 to 275 W Class AB amp. One of these days ... | |
| Why Power Cables Affect Sound @phomchick - Actually I doubt most cable companies could afford the R&D equipment to define their products improvements. I suspect most of these guys are small shops. | |
| The invention of measurements and perception @edstrelow - for that you will have to become a member of AES and read up on their publications. Once in while, they do have a good paper that correlates cabinet movement to tweeter movement. | |
| Which amp will cause a larger increase in electric bill? The only way to correctly answer your question is to find out the RMS current of the two amplifiers at idle and compare them. This is how you do it -> The wattage consumed for each will be the respective current times 120. Divide that pow... | |
| Which amp will cause a larger increase in electric bill? BTW, just to clarify, when I state Class A, I mean the entire amplifier is Class A. There are quite a number of amplifiers that have Class AB output stages with Class A driver and amplification stages. Those amps are still Class AB by IEEE defi... | |
| Which amp will cause a larger increase in electric bill? Actually, if an amp is pure Class A, it won't matter if it is push pull or not, assuming the power output is the same between the two. The reason is the maximum load current flows 100% of the time, so if the power output is the same, then the di... | |
| 2019 calendars "Not I", said the duck. But I am eager to see a source for some! | |
| Which amp will cause a larger increase in electric bill? In general, if it is solid state, I would not worry about power consumption or your electric bill. It doesn't matter if it is Class D or Class AB. Granted Class A amps do consume some power when it is on and idling but most Class A amplifiers ... | |
| Why Power Cables Affect Sound Actually, if one had a spectrum analyzer then one could see the improvement since it is easy to measure the power output with and without the new cord for a given piece of music. Once you have it hooked up, there is a LOT you can measure. Gran... | |
| Thinking of upgrading from pass labs x250 You probably need new tubes for those Citations. My CJ's start to sound constrained, stressed, and a bit weird when they want new tubes. I'd re-tube it and not look back, but I tend to be a tube guy on the midrange and upper frequencies and so... |
