| Using tube amp with electrostatic speakers. @lewm Yes, the tricky bit is that the transformer impedance increases as frequency goes down. So with a given capacitance with increasing impedance, the crossover point moves lower- there is no set crossover point! This is why the resistor is ther... | |
| high-efficiency loudspeakers Ralph is there an established price list for the "Classic Audio Loud speakers" ?It depends on which model and which options. So they can be anywhere from $8000 and up. I've not seen an established price list- just give John a call. @dodgealum , wh... | |
| Why do some amps provide more output power when using a balanced connection? "The Jotunheim is balanced differential. Meaning it will not turn a single-ended connection to a "Fake" balanced connection. You may notice more power from using the balanced headphone output with a single-ended input but I cannot speculate on ... | |
| Rega RP8 or Technics SL1200G Have you listened to an RP 8 in controlled circumstances, and if so, how did it fall short? That would seem to be of help to the OP.From your post I can only assume that the Linn LP12 is not a well regarded vintage machine, as “...all the well-... | |
| Using tube amp with electrostatic speakers. For the example given above where 10 ohms and 36uF values of R and C give you a X-over point of ~440 Hz, removing the R entirely would give you a high pass -3db point at ~4400 Hz. This would leave a big gaping hole in the midrange, because the... | |
| high-efficiency loudspeakers If there is a 'best'... I look at what would be on the short list.Another vote for Classic Audio Loudspeakers. 98 db 1 watt/1 meter, 16 ohms, 20Hz (honest) to 35Khz). Optional field-coil powered woofers and midrange; first breakup at 35KHz so very... | |
| Balanced Preamp recommendations up to $5,500 What about true balanced (ie, dual mono) tube HIGH BANDWIDTH preamp? Does such a thing exist on the face of the Earth?@madavid0 Yes, but to be clear dual mono and true balanced are two different things.Our MP-3 preamp is based on the first balance... | |
| Overloading a preamp input question 9 volts is a lot. You are correct- Redbook Standard for balanced operation is 4 volts. But if the preamp is set up right, it should be impossible to overload the input! This is because the volume control **should** be at the input of the circuit; ... | |
| 20 Year Old Amplifiers compared to 2017 Amplifier technology reached maturity in the seventies, when output transformers were abandoned in solid state amps. Ever since, well designed amplifiers used within their specifications have exceeded human hearing acuity.@cheeg, As I pointed o... | |
| Which watts are the right watts in SS amps? First 5 – 7%? I’ll presume this initial area pertains directly to the scenario you presented, otherwise, isn’t the first 10 – 20% of a class AB amp where one finds Class A functionality, and many adore that area of operation.@blindjim Well th... | |
| Using tube amp with electrostatic speakers. @jazzdude99 Andy, If you want to get an idea of what the Sound Labs can do with the new backplate, there is a resistor that can be removed from the old toroidal backplate that gets you about 90% of the way there. The resistor is usually composed ... | |
| Which watts are the right watts in SS amps? Go ahead and spend gobs of money on those pure class A amps that burnout after 7-10 yearsAny truth to this? (i.e. is a class A amps life span known to be less than other designs)No. We've been making class A amps for the last 41 years, and recentl... | |
| Using tube amp with electrostatic speakers. ESLs on paper have low efficiency, but that is because the standard measurement is made at 1 meter.If the ESL is a large panel, a good deal of the sound might go past the microphone without being picked up. So in reality many ESLs (and planars in ... | |
