| High impedance Speakers I have advocated high impedance speakers for a long time, not just for my own activities, but for the fact that any tube amplifier with a high impedance tap on the output transformer will perform noticably better with a high impedance speaker (in ... | |
| Sonics of Soundlabs Keep in mind that the room dimension issues above apply to all speakers, not just Sound Labs. I have found that having the capability is more convincing regardless of the size of the room.Also keep in mind that to drive Sound Labs you must use a t... | |
| Causes of long term listening fatigue? You are correct- the reason is that our ear/brain systems are tuned to accept odd-ordered harmonic content as *the* loudness cue (read: Listener fatigue) in anything we hear. Anything that causes an emphasis to those harmonics results in listener ... | |
| Attention Minneapolis Audiophiles We've got speakers, amps, everything you need. When you are ready to make your comparison, let me know. If you want to hear what the BAT and Aesthetix stuff does beside the MP-3, I am game for that too. | |
| Causes of long term listening fatigue? LF is caused by odd-ordered harmonic content in the signal, usually harmonics of the 9th order and beyond. These harmonics are emphasized by the use of negative feedback in amplifiers and by non-linearities in transistors (and to a lesser degree b... | |
| Are Horn Speakers good or bad or simply a complete joke? Just FWIW... to get horns and other high efficiency speakers to sound right usually involves an amplifier with a relatively high impedance output. Nelson Pass published an excellent article that raised this issue in Audio Express around the beginn... | |
| High impedance Speakers Classic Audio Reproductions makes two 16 ohm speakers, the T5 and the T1, which are both moderately high efficiency too (95 and 97db respectively). | |
| Progressive Rock You can't talk about Prog these days without mentioning Porcupine Tree. Most of their stuff is on LP too.My system, while not designed to play rock at all, is fine with it (and I tend to be brutal about it...) and I am one of those at the shows th... | |
| Attention Minneapolis Audiophiles Hi Art,I'm game! | |
| Subtlety ? do any American amps do it? Yes. Is this a trick question?? | |
| Our we Lazy? Ease of use vs performance has been with humans for a long time. Its still not a good excuse though. If the goal of this hobby is to get as close to the recorded sound as possible, then ease of use issues have to be tolerated in that quest, to som... | |
| why does preamp improve sound quality? OK- Here's how the preamp line stage should function. The problem is that the interconnect cable has electrical parameters, capacitance for the most part, that interacts with the signal. The higher the impedance, particularly of the source, the gr... | |
| why does preamp improve sound quality? One thing that no-one seems to be mentioning is that the line section of a preamp also has to control the interconnect cable. The better they do this is often also part of the measure of quality a preamp can portray. Passive controls do not contro... | |
| tube amplifier auto bias- accurate? Hi Eldartford, actually semiconductors are nice for self bias as they allow for a higher operating voltage. Since the bias voltage for the power tubes is usually developed across a cathode resistor, that means that the B+ available was the power s... | |
| tube amplifier auto bias- accurate? My 2 cents: There's a bit of confusion here about autobias and self bias. Self Bias has been around for decades and has been used by many manufacturers over the years.Autobias is a modern varient of Fixed bias. Fixed bias is the correct way of say... |
