| Better than a CAT? The Merlins are a very easy load and they show off a tube amplifier very well! | |
| Power amps for Quad electrostatics 2905 Newer Quads have a lower impedance than the older ones, as Quad contiues down the same path that Martin-Logan took, trying to get transistors to work with ESLs. But the nature of ESLs is that tubes will drive them without high end empahsis and bet... | |
| Why does it sound better at lower volumes? If the problem is volume related, either your room is getting over-driven at higher volumes or physical vibration is upsetting your front-end. The latter can be solved by proper equipment stands and anti-vibration platforms- probably for the signa... | |
| Experts: Why is preamp important? preamp functions:1) provide volume control2) input switching3) provide any needed gain or attenuation4) and least understood- control the interconnect cable between amp and preamp to minimize the effect of the cable. Most sources cannot do this BTW. | |
| Why do amps sound different? Tvad, it can be (usually not clipping though), but there are other things that can do that that I would think would be more likely. Resonance excited by volume in the system is where I usually start when looking to kill sibilance. Cartridge setup,... | |
| Better than a CAT? Things sure go in circles! The RM-9 was one of the benchmark amplifiers that we felt it was important to compare to, back a good 18 years ago. I'm guessing that the RM-9s back then were not 'SE'. | |
| Why do amps sound different? Kirkus, sounds like he did! Since a feedback signal is one of voltage, to satisfy the test might be easier than you think. Just place a speaker with a test tone coming out of it about 1 foot in front of the speaker under test and measure the AC vo... | |
| 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 ... |
