| 8 Vs 4 ohms Hi Eldartford, actually the 16 ohm tap is twice the number of turns as the 4 ohm tap. The 8 ohm tap is in between. The impedance of the winding goes up by the square of the number of turns. So the 4 ohm tap is the center tap between 0 and 16.Also,... | |

| 8 Vs 4 ohms If you load the 8 ohm tap with a 4 ohm load, the plate to plate impedance that the tubes are supposed to be driving will be reduced. This will result in less power and increased distortion (the 'loosness' that others have mentioned).This is harder... | |
| which preamp sounds most transparent? Only problem is, you can't control the volume. If you use the digital volume control that is the typical fare, you can expect it to sound worse than using a preamp.The other problem is that not all CD players can control the interconnect cable, wh... | |
| best preamp ever - cost is no object 21 entries and more than 21 candidates! I bet there are more than that. So here's my recommendation:1. Go with tubes.2. A good preamp can drive interconnects over 25 feet with no ill effects at all.3. Avoid remote control volume systems except tho... | |
| Transformer based passives vs passive stepladder The problem is that you have to control the volume somehow. In active line stages and in the case where the passive is at the input of the amp, there is no interconnect cable that has to be controlled. It does seem that the interconnect cable (in ... | |
| Transformer based passives vs passive stepladder The problem you have is that all passive devices will have an artifact unless they are directly at the input of the amplifier. The reason is that the interconnect cable, even if very short, plays a major role in the results that you get. Resistive... | |
| What is the lifespan of a good SS Amp Atma-Sphere has a 20-year design rule for the simple reason that 20 years is about as long as you can reasonably expect filter caps to hold up. After 20 years, even if they have not failed outright, it is a good idea to replace the filter caps any... | |
| Vintage Tube Amps, I'm Lost The ST-70 is a good place to start. Very nice output transformers and simple enough that the driver and power supply are easily upgraded/updated. 35 watts is about as high as you are going to see in an integrated and is not enough power unless you... | |
| Future of analog controlled class 'D' amps? Ndeslions, I'd like to agree with you because I could stop with the foolishness I'm in up to my neck with already. But the amps you mentioned don't challenge even what *I'm* doing so imagine what would happen if someone came along that could get i... | |
| 4 ohm vs 8 ohm taps If you have an 8 ohm speaker, use the 8 ohm tap. If you use the 4 ohm tap, the transformer will not be loaded correctly and will 'ring' that is to say it will add distortion, which usually makes the amp sound brighter (though not always).Conversly... | |
| Future of analog controlled class 'D' amps? A lot depends on the 'Class A' amplifier. Do you mean class A transistor- maybe, if class A transistor amps do not improve at all in the future- which is unlikely.Given that class A tube amps will not improve at all in the future :), again maybe. ... | |
| Overpriced Tube Amps I think you are right :) nevermind.... | |
| Overpriced Tube Amps In 1968 you could be a nice Cadillac for about $5000. Nobody bats an eye at $50,000 for a nice Cadillac now.A Marantz, 7C, 9 and 10 cost you a cool $1600, another $700 for the Dayton-Wright ESLs, $200 for a turntable with arm and cartridge and $20... | |
| balanced vs unbalanced If you can run balanced- do so. Balanced cables are more effective than their single-ended counterparts and the system will sound better for that reason alone- assuming that the amp is indeed balanced internally. The original balanced standard was... |
