| CES 2010 and THE SHOW This year had the best foot traffic I have seen at T.H.E. Show in years. It was fun seeing Harry Pearson's presentation, and the food was great! I heard several reports that CES only had two floors this year so it appears that it was about 2-2 1/2... | |
| Using XLR for Phono out John_tracy, just for the record, to do things balanced does not double the parts (its about 50% more) and the noise is actually **lower** for a given stage of gain, not higher! The noise is theoretically 6 db less per given stage of gain; this can... | |
| Amplifier for Klipsch Cornwalls Winoguy17, no worries! Not all tube amps are equal :) | |
| The closest approach: what amplification? Ggavetti, I completely agree with you. To be clear here though, its not the audiophiles that need to understand this stuff, its the **designers**!IOW when you see designers building equipment that follows the human perceptual rules rather than ben... | |
| Amplifier for Klipsch Cornwalls Those 15 inch woofers can sound slow and mushy with tubes.The size of the woofers has nothing to do with the speed of the amp; this is a common amplifier myth. It turns out that if the woofers are over-damped, that that can slow them down, IOW if ... | |
| The closest approach: what amplification? If you are going to make progress with audio, the first thing you have to do it look at the way the human ear perceives sound- IOW understand the rules of human hearing.Unfortunately while the bench specs we are so used to were being developed, re... | |
| Amplifier for Klipsch Cornwalls Most high efficiency loudspeakers get their efficiency from tight gaps and precise construction. As a result they are highly reactive and are over-damped with anything more than a very moderate output impedance from the amp.IOW, a tube amplifier w... | |
| Zero Autoformer good/bad for Atma/Quad combo Jwm, just for the record, all ESLs have an input matching transformer. So if you used a set of ZEROs with a transformer coupled amp you would be passing the signal through three transformers if you were using ZEROs. Even though we are an OTL manuf... | |
| Which tube monos? So many choices.Very intimidated FWIW the 2.2 ohm figure is not a problem for any tube amp because it is at higher frequencies and is not broadband. Its actually more of a problem for transistors that make too much power into that impedance! The rising impedance at low frequencie... | |
| low output mc: noise free listening possible? My experience has been that low noise is possible with tubes as well as transistors. You can do it by going fully differential. Contrary to Herman's comment balanced operation in fact offers you lower noise and immunity to artifacts in the interco... | |
| Using XLR for Phono out R_f_sayles, almost all phono cartridges are balanced sources. Many arms are too. The signal is converted from balanced to single-ended usually in the way the RCA cables are connected to the arm. That is why there is that weird grounding wire that ... | |
| Questions on switching to tube amplification The 2Ce's are very tube-friendly!! You won't have any troubles finding something to work with them. | |
| Cartridge Loading Dertonarm is absolutely correct on this one. BTW I have yet to see a MM that actually loads correctly at 47K. Most are more like half that and I have seen Grados that are closer to 10K. | |
| Can someone give me an explaination re: power amp. Neubilder, I'd be one of those! So far the most accurate speakers I have heard are 98 db 1 watt 1 meter. They go from 20Hz to 40KHz and have the same transparency and detail of the best ESLs but dynamic range no ESL or magnetic planar can hope for... | |
| The Hub: Futterman H3: Seen one lately? It was Cecil Hall that had the first Circlotron patent, although he did not call it that. BTW the Graaf amplifiers use the Hall approach which incorporates the driver circuit into the output section. The Wiggins amplifier got a patent also, and is... |
