| Would I be wasting my money to get a turntable? @fritzenheimer Master tapes from the 1950s, 1960s, 1970s and into the 80s have all degraded. Some are lost. So if you want to hear any recordings from this era and want to hear them at their best, you use a turntable and get LP pressings as origin... | |
| How many subs? I found whatever I did, multiple subs interfered with the sound from the main speakers. @bilateral In that case they weren't set up correctly. The most common problem is crossing them over too high! Here's a tip for your sub. Point it at an a... | |
| Pass....Accuphase....or...... If you have a minute....I need ideas in that price range...+/- $$. Thanks! @southofdallas There are class D amps out there now that are every bit as musical as the amps in your original post. Less heat too, and less cost as well. | |
| Question about high current amps versus "not high current amps" Therefore, my conclusion is slew rate is important to SQ, though not as much impedance matching, To the physicists and electrical engineers, is my conclusion valid? @jsalerno277 No. Its a lot more complicated than that. Slew rate is only one of... | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? So, a good SET with matching high sensitive speakers will be a huge step over any vintage push-pull amplifier including Dynaco. @alexberger I suspect your sample size is a bit small to be making that conclusion. For example I think the ST35 is ... | |
| Question about high current amps versus "not high current amps" @thecarpathian 'Output devices' means components in the output section of the amplifier; usually power transistors mounted to a heatsink. We make both class D amps and tube power amps so in their cases either GaNFETs or power tubes. | |
| Question about high current amps versus "not high current amps" so what might be the instantaneous currents provided in music reproduction, even for a few milliseconds? @mclinnguy The instantaneous power will be within the output power limit of the circuit. Therefore so will the current (else the amp fails... | |
| Question about high current amps versus "not high current amps" I’ve always thought the higher capacitance reserve an amplifier has, the more amps it can deliver when needed. This isn’t correct? @thecarpathian That isn't correct. By that metric our MA-2 can deliver more amps that most solid state amps of th... | |
| Question about high current amps versus "not high current amps" @mclinnguy This statement is false: A Coda 16 has 280,000 uF of capacitance and can deliver 100 amps of current, per channel. Here’s why. As @immatthewj points out, the power the amp makes is equal to the current times Voltage. The actual Powe... | |
| Question about loading with an SUT I use five different carts and use one SUT currently wired at 1:10. @theflattire If you hear differences between the cartridges its likely got more to do with loading the transformer correctly than anything else. @adam8179 That method I mentio... | |
| So I Just Bought a Cassette Deck A checkout shouldn't be expensive. If sorting out the power supply I'd expect $200 might be pretty close. | |
| Your journey with lower-watt tube amps -- Can a kit be good enough? Do you think the issue is not voltage swing of driver but the current and power it should drive on capacitive load. @alexberger Generally speaking, yes. Specifically you want to be able to swing the Voltage without distortion. To do that the so... | |
| So I Just Bought a Cassette Deck Deck was just serviced by the previous owner, @jaybe If you can, ask the previous owner if the power supply filter capacitors were replaced. Any cassette machine is old enough these days that these parts should be replaced if the machine is to ... | |
| Question about loading with an SUT I’m wondering if there would really be much of a difference if I had an SUT with the exact ratio and loading that is specified rather than "getting close?" @adam8179 Transformers will ’ring’ (distort) if insufficiently loaded and will roll off ... | |
| Who positions their speakers straight ahead (zero tow in) and why. In both cases I ended up with tweeters on the inside and zero toe in. I like the more immersive soundstage I get with zero toe in. I sacrifice a little of the lock in for the center image. This can work fine with some speakers if there's no sid... |
