| Tube Amp lower power vs higher power and cruising volume Usually in tube amps (with output transformers) the smaller amps are the better sounding, usually on account of the output transformer, but also in how the power tubes are driven by the driver circuit (by far the lessor variable). If you don't ove... | |
| High end Class D amps? The answer is simple: Gain knowledge instead of made up stories. These are words of someone either in denial or in product protection mode.George, as a simple tip: the ability to admit that you were wrong is a strength, not a weakness. In my quot... | |
| High end Class D amps? How can anyone believe that "any" Class-D driving a pair of Wilson Alexia etc etc could possibly do anywhere near the sonic job that an amp like Gryphon Antllion or similar could do. Especially in the lower bass where the Alexia's are 0.9ohm loa... | |
| High end Class D amps? Now you go find a Class-D that will keep pushing even more current into that kind of loading like a good bi-polar amp can.You mean like, *most* class D amps?? Because its most of them.@jaytor I've found that dealing with George means you have to ... | |
| High end Class D amps? Class-D semiconductor devices operate in saturation and would not be impacted by this.That, and the fact that the amp has an output impedance of a handful of milliohms. Phase angle isn't going to affect it. | |
| Control volume with DAC or Preamp? George is omitting the rest of Nelson's comments when he makes that quote. He seems to do this as part of his 'product protection' program, since he sells (actually a very good, but also obviously not of his own design) passive volume control. Her... | |
| Class A triode - on/off on remote? There's really no point. Other things in the system have to be turned on too. The preamp has to be first. So no point in using a remote. If a preamp has it, its only because they could implement it, not because its actually practical. | |
| High end Class D amps? Why would a Class-D amp care about phase angle?In a nutshell, any good class D amp wouldn't. | |
| HDMI to Analog Decoder/Converter? You might consider an HDMI to USB adapter, which can then be plugged into a DAC. | |
| Control volume with DAC or Preamp? Quite often the volume control in a preamp is better than one in a DAC. This is usually true if the DAC employs a digital control, since digital controls usually shut off bits to lower the volume, resulting in lower resolution as the volume is red... | |
| DYNACO Pre-Amp PAT-4...with an added Volume knob Not heard of that. You might hook it up and see what happens- does it control the main outputs? Does it control the recording outputs? That will give you a good idea if you need to do anything about it. | |
| Driving different pairs of speakers with different speaker wire lengths Its unlikely that the different speaker cable lengths are doing anything bad, unless the cables have some sort of high capacitance which is known to mess with certain designs that have poor phase margins. If the cables simply have two conductors s... | |
| High end Class D amps? In general, solid-state (ss) amps reproduce deep bass frequencies better than tube amps. A good indicator of an amp's bass reproducing ability is its Damping Factor, which basically measures its ability to control, or start and stop, the bass... | |
| High end Class D amps? class d greatest strength is outstanding bass, so yes on that frontbut dual subs are much better than one... some will even say the best way is a 'swarm of subs' to smooth out the deep bass response, which can be very lumpy and hard to modulat... | |
| 100 W Tube Amplifier Malfunctioned As a tube equipment manufacturer, I don't buy the scenario. If one amp is running fine, something else is up. When the input voltage is lower, the current through the transformer is lower- which if anything, would prolong its life. |
