| 120/115V vs. 100V .Low voltage can be harmful, but this depends in part on the way the power supply is designed. If it is a regulated supply, and the voltage is close enough to be within the regulator range there would be no effect at all. I don't think that there ... | |
| Does DK Design actually design and manufacture? In today's world "Cheap" often reflects an efficient manufacturing process rather than poor performance. Many people still think that quality requires a higher price, and therefore equate high price with quality. Audiophiles tend to be in that gro... | |
| 8 Vs 4 ohms inpepinnovations@aol.com...If the 4 ohm and 8 ohm taps have the same voltage (per your comment) why do we have two taps? Actually, the 8 ohm tap has twice the windings of the 4 ohm tap, and puts out twice the voltage as Cford noted. So, for a give... | |
| Servo controlled speakers and subwoofers sirspeedy70680@earthlink.netMaybe 57 is "well under 60", but if I figure it correctly this is only 0.45 dB down! It's closer than you think. | |
| What is under your TT, cheap islolation? I don't know why people continue to have problems with TT vibration. Mine went almost completely away about thirty years ago when I got an Empire TT which had two features of interest. (1) The platter and the arm moved together on soft springs. (2... | |
| Transformer Hum As Newbee sez...a ground loop or interconnect alongside a power cord could cause hum, but I assumed that you have ruled such things out already. Evidently your other vintage amps don't exhibit the problem. | |
| Transformer Hum The most likely reason for hum with an old power amp is tired (old) electrolytic capacitors in the power supply. Replace them. If there still is a problem then look into other things. | |
| Servo controlled speakers and subwoofers A servo involves a sensor on the controlled device (in our case a small accelerometer on the woofer cone) which measures movement of the cone. With a non-servo system the power amp puts out a voltage according to the input signal. The voltage is a... | |
| VCR for analog TV as well as HDTV Not too long ago I bought a JVC VCR for a few bucks over $100, mainly to fill the slot in a TV/HT setup, and, on very rare occasions, play a tape. Viewed on a 42" EDTV plasma the picture is much better than I expected. It does depend on the partic... | |
| Does DK Design actually design and manufacture? DK Design operates like most other manufacturers. Try another question. | |
| EQ's... why doesnt everybody have one? Henryhk...Digital Sound Processing (DSP) which includes EQ is almost universally done using a 32bit floating point processor called SHARC from Analog Devices. Google it. It, and everyone else but Sony, works with PCM.SACD does not output digital, ... | |
| 2-channel listening with a sub-woofer I have heard a lot about how hard it is to "integrate" a subwoofer with planar speakers like my Maggies. In my custom designed subwoofer system,I have been very successful in this regard, and I think that the reasons are as follows.1...I went with... | |
| 2-channel listening with a sub-woofer As usual, small diameter drivers are said to be "faster".Frankly I have never heard a "fast" 16 foot organ pipe. I think that what we really mean is that the cone is under tight control of the power amp, and this depends on the power of the driver... | |
| EQ's... why doesnt everybody have one? Nuguy...It's not the system being corrected...it's the room (mostly). | |
| 40hz room mode RPG Modex Corner trap? Nikturner920...Although I do have LP, my best source (IMHO) is a Denon 2900 with Underwood mod, via unprocessed pass through of Rotel 1066. My three DEQ2496s are between the preamp and the power amps. It would be better to use a TAPE loop (unaffec... |
