| Musicality vs Transparency & Detail The way you get 'detail retrieval' is to not create distortion. Distortion obscures detail. The way you keep it musical is by not adding subtle distortions that are sensed by the human ear as loudness cues (odd harmonics). Feedback as a source of ... | |
| Will an RCM make the Rice Krispies go away? FWIW I've found that phono preamps with feedback, particularly transistor units, will often enhance ticks and pops. When I started listening to zero feedback (passive EQ) preamps, I found that my LPs were a lot quieter than I had thought they were. | |
| Trying to match impedance It looks to me as if the Threshold was built to meet the balanced line standard, which is low impedance. The input impedance is set low to reduce ringing in line matching transformers that drive the input.There are not that many preamps that can d... | |
| Turntable Pre-Echo Sound....? I agree with UC -mostly- on this one, although working with mastering LPs, I find that pre-echo is actually a tape phenomena rather than LP. It indicates that the tape was stored before the LP was mastered- not a good idea as the energy of the tap... | |
| Zero feedback and class A,which is better? T_bone, you got it exactly right. Most SS amps make constant voltage with respect to load; on ESLs that is not the right response.With respect to the ZERO/OTL thing, we made a device similar to the ZERO about 10-15 years ago. It got to be a bit of... | |

| Zero feedback and class A,which is better? 'Lurk' is hardly the term!For a speaker like this, a zero-feedback amplifier will need a little help. Fortunately there are two things going for you- the first is that the speaker is an ESL and the second is that there is a way to deal with the im... | |
| Break in period Shadorne, if I get your comments right then I agree with them 100%. I feel very much that all components have their place and application.Component stability (I would think) is as important in audio as in any other application. To that end one of ... | |
| Break in period Shadorne, I wonder if you might clarify this statement:This is just one of the many reasons that modern electronics designers mostly use SS amps with feedback for low voltage level applications (tubes are still used in some very high voltage appli... | |
| Life of amp internals Electrolytic caps have a half life of about 20 years- in that time about half of them will have failed. The transistor amp above that is 30 years old has a seriously degraded power supply; despite that the amp still plays although at reduced perfo... | |
| tubes and analog Got that right! | |
| tubes and analog Rauliruegas, you can do better than that! First though you are going to have to figure out what the behavior of our amps actually is during a tube failure. So you have some homework to do. Then maybe you'll be able to create a more convincing story. | |
| Phono Stage - Passive Pre- Amp: Results?? Pawlowski6132, cable capacitance does play a role, but a more complex one than generally meets the eye. In addition to high frequency rolloff caused by the high output impedance of the passive control and the cable capacitance, the interconnect al... | |
| Tube amp for Sound Labs The last version of the SL *before* the 'torriod' option was introduced was an easy load for our amps- even the M-60 did quite well on them. When the torroid option was introduced, along with it came the low impedance in the midrange that Albert r... | |
| Phono Stage - Passive Pre- Amp: Results?? If you are running passive between the phono preamp output and the power amp, you will find that keeping the interconnect cables as short as possible will be very beneficial. |
