| Why do amps sound different? Kirkus, Your technique for the D130s should do the job. I'm not so sure about the other but why not give it a try?I had one of those Knight 6 watt amplifiers too. FWIW the AR-3s really like power; I have a zero-feedback Dyna ST-70 that barely has ... | |
| Why do amps sound different? Hi Kirkus, I have a set of AR-3s myself- I use them for monitors. They are power hungry but they like low feedback amps just fine. Actually, the idea of putting a resistor in series with a transistor amplifier is a good one. Nelson Pass suggests t... | |
| Which speakers will fill 5,000 cubic ft coherently It seems I need to clarify something here. My comment above referred to **all** tube amps, not just Atma-Sphere (and FWIW, our MA-2 is quite comfortable driving four ohm loads).However- what everyone in audio (and thats a lot) need to realize that... | |
| Are horns and hi-eff designs becoming more popular Mlsstl, I've heard horns that honk too. That does not mean they all do! I too have been at this a long time as I suspect many of the 'goners have, like you about 40 years also including professional recording and mastering. As you know, having acc... | |
| Why do amps sound different? Kirkus, the Acoustic Research AR-1 is a good example of a speaker that was designed with intention to be used by a 'current source' amplifier. They recommended an amplifier with an output impedance of 7 ohms. Sure enough, it actually does sound be... | |
| Are horns and hi-eff designs becoming more popular Mlsstl, the 'honkiness' you refer to is real, -but- it is usually an artifact of using the wrong kind of amp on a horn. Amps with low output impedance can get strident and honky as the highly reactive horn driver can put an amp with lots of feedba... | |
| Why do amps sound different? Hi Kirkus, I'm not the one who has created these paradigms; they simply are what is. And for the record, you would be hard pressed to build a tube amp of the type you describe! Even if you ignore the taps of the output transformer, most tube amps ... | |
| Rich; organic true balanced amp w good detail $6k Sutts, FWIW there are amplifiers out there that run as hot as OTLs. In fact, OTLs only run hot if they are class A, not due to the number of tubes. It has to do with the energy that is dissipated in the output section, not the number of tubes.For ... | |
| Why do amps sound different? Phd, one of the distinctions of the Power paradigm vs the Voltage paradigm is under the Voltage paradigm, the specs often have no meaning as you already know. Under the Power paradigm, the specs correlate with what you hear. | |
| Phase switch on pre amp use? The phase switch is likely to be audible only if you have a recording that is completely phase coherent- using 2 or 3 mics in the recording. Any more than that and the phasing information becomes too confused to hear the effect of the switch. I'm ... | |
| A question about front-ported speakers I have my speakers 6" from the rear wall and they work great! The ports are front-firing.But- the front of the speaker is about 2 1/2 feet from the rear wall, so maybe they don't count? | |
| Why do amps sound different? Amfibius, take a look:http://www.atma-sphere.com/papers/paradigm_paper2.html'Current source' is a Voltage paradigm term for amplifiers that have a high enough output impedance such that they exhibit (or at least try to exhibit), constant power wit... | |
| Current Trends in multi thousand dollar speakers Sean's assertion that an increase in impedance results in 'less power, less control' is incorrect. In fact 'control' (which is a poorly defined term and can only be related to damping factor) increases with impedance. Furthermore, many tube amplif... | |
| Tri Planar / ZYX Universe soundstaging Hi Terry, certainly. If you have heard a proper reel-to-reel system, one thing that strikes you regardless of whether it is a master tape or a dub, is the quality of imaging solidarity and the black background. Also, there is simply no strain when... | |
| Why do amps sound different? Although alluded to before, it seems that the amount of negative feedback is a big issue.2 amplifiers can easily have the same bandwidth, but one running with feedback and one without. The one without will likely sound more relaxed, since it lacks... |
