| Cleaning amp/preamp If you have a board contaminated with oil a car wash (the kind where you use a pressure wash and do the cleaning yourself) can be a good move. I've had to do this a couple of times when customers put weird 'contact enhancers' on their tube sockets... | |
| Can you do anything to make power tubes last longer ? If you’re talking about the US, you are mistaken @atmasphere. Nominal voltage in the US is 120VAC ±5 percent, so anything between 114VAC and 126VAC is normal. That is established by ANSI C84.1 standard. @cleeds I stand corrected. However if t... | |
| Mullard EL34 that sounds best And as far as type I and type II, I see a set they are specifically calling EL34s type II and the rest are just EL34s, so are the ones that are called EL34s the type I? @inna as best I can make out the difference is how much plate Voltage they... | |
| Pick it Pro Balanced cartridge? real balanced? any good? So there is nothing unusual about the cartridge in the advertisement, good or bad. In balanced mode, the "hot" lead by convention carries the positive phase of the audio signal, and the "ground" lead carries the negative phase. Ground floats. ... | |
| Can you do anything to make power tubes last longer ? @inna For longest tube life: 1) keep the tubes clean and free of fingerprints. 2) keep them biased properly, if you can run them a little below spec. This works only if the sound isn't adversely affected. 3) use the Standby switch to warm up th... | |
| Somebody Please Make This Already... @eddnog We looked at something like this but the simple fact is to do bass management properly you start with a distributed bass array; four subs placed asymmetrically so to break up standing waves and thus have flat bass response everywhere in th... | |
| This Might Not Exist, Any reasonably priced, smaller speakers with 100db Sensitivity? If you don't mind DIY you could install a Tangband 1772 driver in a sealed box and supplement it with a tweeter (both crossed over properly to avoid comb filtering). Its 97dB and in a reasonably sized box (bigger bookshelf) would go to 45-50Hz. I... | |
| Mullard EL34 that sounds best @inna Mullard made a 10,000 hour EL34 FWIW. I've not seen one in 40 years or so. I doubt you're interested, but if you were to try new EL34s, if it were me I'd be using one of the JJ types (they make two) or something from Psvane. Considering ho... | |
| More on XLR vs RCA considerations? How on earth do we know if our gear supports AES48? @billpete You could ask the manufacturer. | |
| Thinking about going electrostatic Speakers would be powered with a rotel 1090 and prima luna dialogue pre amp. Have never herd of that type of speaker. Would like to here your thoughts @bill1957 You might look into an ESL called Popori. Some of their speakers are very easy to ... | |
| Are EL34 based amps more musical than KT series based ? Or it's purely a matter of design? it's purely a matter of design @inna That's the answer. If you want to hear a really musical KT88 based amp, the Harmon Kardon Citation 2 (properly refurbished) is a good place to start. It makes a difference too if the amp is pentode or Ultr... | |
| More on XLR vs RCA considerations? Perhaps if the circuitry (caps etc.) becomes equal between the two, there is not much advantage to XLR? Not sure, myself. I like to have the option even though I've never used it, just makes me feel good, knowing it's there if I ever decide to us... | |
| Spatial Audio Raven Preamp @yyzsantabarbara The Raven employs an output transformer so should support AES48. There is a correct loading for the output transformer that will prevent it ringing- you might inquire how that is handled. Traditionally if the output transformer i... | |
| Balanced vs RCA preamps As for @atmasphere, he simply won't accept that his opinion that the only proper way to build a balanced component is to make it consistent with the AES48 standard is simply his opinion. It's one that most of the high end community has rejected b... | |
| Balanced vs RCA preamps It’s a red herring, really and you’ve already acknowledged that AES48 is not commonly accepted in home audio. You describe your MP-1 preamp as "featuring Balanced Differential Design®" and state it’s "still one of the very few preamps to support ... |
