| Is it too bright or is it high resolution? Bright is a bad thing. Its a coloration.Detailed is a good thing.Quite often the two are found together. This gives detail a bad name!Its possible to be extremely detailed and yet quite relaxed. Brightness is often not an actual frequency response... | |
| 6C33C tubes - sonics, implementation & availability ^^ the survival guide is good with one exception; Romy's assessment of the Japanese socket is flat out mistaken! They actually have a shorter life than the ceramic sockets and should be avoided. This is because the 'plastic' he refers to is actual... | |
| When and how did you, if at all, realize vinyl is better? We've showed with a lot of excellent digital gear at shows. One of the best was the Stahltek, so far ahead of the dcs, msb and the like that quite often I found myself looking at the turntable to see if an LP was playing. IOW it was pretty darn mu... | |
| When and how did you, if at all, realize vinyl is better? You will realize vinyl is better if you like snaps, crackles and pops.In many cases ticks and pops are actually artifacts of the phono section; while the actual tick or pop is on the LP surface, if the phono section is unstable it will exacerbate ... | |
| Why does bi-amping speakers sound better? I've not found that biamping works all that well but there are a ton of variables.Two of them are amplifier quality and speaker quality.A third is the quality of the crossover- which is certainly one of the more important variables!Now the amps I ... | |
| When and how did you, if at all, realize vinyl is better? It always sounded better to me. Early on using digital recorders, I noticed that there was this weird distortion, which is an intermodulation with the scan frequency. If you record with an analog sweep tone, its easy enough to hear the distortion.... | |
| Transformers humimg........again A balanced transformer does not seem to sort the problem of DC on the line although it does have advantages.There is a simple circuit consisting of a bridge rectifier and four electrolytic capacitors (bypassing the rectifiers in the bridge in reve... | |
| KT88 tubes for Monos Why- simple. You play guitar or bass- maybe you go on tour. A tube dies. If its a KT-88 its a simple matter to nip down to Guitar Center or the local guitar guru and fetch one up. If a KT150 you are so out in the cold... | |
| Transformers humimg........again What is your line voltage? It should not exceed 125V for more than a second. If its high that could explain the problem. The PS Audio should be able to correct that. | |
| 6C33C tubes - sonics, implementation & availability There is no such thing as a 'heavy duty socket' for that tube!! The typical warmup time is about 5 minutes.We recently reissued the Novacron in an updated version. Its a popular tube with OTL manufacturers. In fact most OTL manufacturers use it; y... | |
| High quality Speaker switch box for multiple amps? You would have to build a custom box. I recommend Grayhill switches if you want something that won't completely destroy the sound. You'll pay a bit for one but they are some of the best for something like that. | |
| 6C33C tubes - sonics, implementation & availability We were the first company in the US to use that tube (in our Novacron amplifier, about 1991). You are correct- the tube stopped production about 1999 when the plant making it went offline and was torn down. There do seem to be large numbers of the... | |
| Is It Safe to Warm Up Power Amps Without Speakers Attached It depends on the amp! A H/K Citation 2, Dynaco ST-70, no worries. Our stuff is no worries. Some amps (tube or transistor) can go into oscillation. Its best to check with the manual or manufacturer. | |
| How much gain is needed in a Phono Preamp for a 0.2 to 0.3mv low output moving coil? If the noise floor is low enough 57 db might be fine. But the phono gain isn't the whole thing. The gain in the line section, the gain in the amp and finally the efficiency of the loudspeakers all make a difference!So if you have 57 db, a passive ... | |
| Voltage source vs. current source amplifiers In broad sense, it appears that the amplifiers that increase their power as the load impedance drops - ideally double as the load halves, are voltage sources and the ones that maintain the same power, or close to it, regardless of the load imp... |
