| Impedance matching between 2k ohm phono pre and 100k ohm amps via passive pre The low impedance is on the drive side so that is not a concern. | |
| Amps Atma-Sphere M-60 Mono blocks OTL design I do not think the ZEROs will be useful on this speaker.The ZEROs should always be regarded as a problem solver (and for any amplifier). The problem is that the amp sounds worse without them, in a nutshell. If the amp sounds better without them th... | |
| Is It Safe to Warm Up Power Amps Without Speakers Attached It will damage tube amplifiers.Worse yet is "moving over" speaker wires to the amp while its powered up. A good way to damage, possibly permanently, the output stage of the amp.These statements are false. What is true is that some amps are stabl... | |
| Tube Pre+ Transistor Power will burn your power Amp. easily? I agree with your other responses, I think this is not valid but I'm not certain. I'd like to find out from an expert just to be certain.Some consider me to be an expert... the idea that a tube preamp can do anything to a solid state amp in pa... | |
| Tube vs Solid State Would this be a good time to add those Zero autoformers that Ralph advocates?Maybe.What I was thinking is that hard to drive speakers are hard to drive. As the many posts in this thread are pointing out.Amps of any persuasion don't like working ha... | |
| 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... |
