| Current mode vs voltage mode Hi Bob, -you got it backwards- the higher output impedance amplifiers behave as 'current sources' rather than 'voltage sources'.Actually the two concepts are a bit misleading and counter-intuitive. A low impedance source is so because it can make ... | |
| Tube amplifiers that really drive MBL 101E's The MA-2 is full power to 1 Hz. The impedance curve of the MBL has no severe dips and is actually an easy load as far as the MA-2 is concerned. | |
| Recommendation for Computer/Digital Hi Ghunter, yes, the jitter issue is only during playback. On our system we buffer the playback from the hard drive through memory. The idea was to create a dedicated transport- thus the zero latency configuration (we found on Windows that the sys... | |
| Recommendation for Computer/Digital For audio, Linux is your best setup. You can configure the kernal for zero latency, which is something you cannot do with other platforms. Then use 'CD Paranoia' to read the CD onto the hard drive. Playing the CD back at that point you will have a... | |
| Tube takeover FWIW, we had enough go-arounds in the past with New Sensor that we started sourcing our own tubes (right now none of our tubes are made in Russia). The writing was on the wall about this 2 years ago- if I were him I'd pull all the tooling and move... | |
| Choice of tube amp? Bombaywalla, the first thing to do is drop the notion that tubes are voltage devices and transistors are current devices. While it is true that tubes run more voltage and less current, and transistors more current and less voltage, to think in bla... | |
| Tube Characterization: 6DJ8, 6922, 7308, CCa, etc Mrtennis, you might reread the caveats I included earlier. However I might also point out that this experience is from working with literally thousands of tubes. I do agree that the tube type ought not be the criteria for selecting a component, al... | |
| Tube Characterization: 6DJ8, 6922, 7308, CCa, etc Ah- OK. The 6SN7 will *generally* offer you smoother sound with less 'hash', especially at higher volume levels where airbourne vibration can affect the tubes. Detail will be the same and 6SN7s will generally allow you more drive ability as they w... | |
| Tube Characterization: 6DJ8, 6922, 7308, CCa, etc Tvad and Neebee, there is no doubt that I support my design decisions !! :)-And the reason that I made those decisions is based on the experience that I had with the tube types I mentioned. The 6DJ8 was a popular intrumentation tube (look in an ol... | |
| Choice of tube amp? If you are running ESLs it is the nature of the technology that you will have to run tubes for best results. ML has set up the speakers at a low impedance in an attempt to make them work with transistors, but it is only half successful as you stil... | |
| Tube Characterization: 6DJ8, 6922, 7308, CCa, etc I agree with Albert too. Having said that, I will now proceed to step on some toes so please excuse me for a moment :) : 6DJ8/6922s are not a good tube for audio despite what you might hear here. The reason is they have a tendancy to microphonics ... | |
| Contrast/compare 50W tube amps FWIW the M-60 is fine with speakers that are described as above. The amp is not quite *that* load sensitive (as many tend to think it is). Most speakers that have a dip to 4 ohms due to the crossover will work fine. The real issue is efficiency- i... | |
| Solar Electric/Battery Driven System? If you are planning solar power, the advances in the area in the last 10 years have been profound. I wouldn't worry too much about the amplifier technology. If you are serious about solar power, the other items in your home (usually lighting, appl... | |
| Can tube preamps be as 'detailed' sounding as ss? Sean, tubes *are* as fast as transistors, else vacuum-tube radio circuits could not exist. There are many things that limit bandwidth in tube *designs*, but tubes are not the culprit (check out the risetimes on our website sometime). Soft clipping... | |
| Can tube preamps be as 'detailed' sounding as ss? IOW means 'in other words'.The 'citation' I've been referring to is the study by General Electric that was done back in the 1960s. In it, they found that people will tolerate quite a bit of even-ordered harmonics added (up to 40%), but were not to... |
