| "Breathing" of the air 'Air' is one of those things that, IMO, all audiophiles think that they are talking the same meaning, when I think you will find that there are several predominate meanings.For me, 'air' is the ability of speed in a system, in a way that allows fo... | |
| Grado 10K Ohm Loading? In the past (before the wood body Grados appeared) we ran the loading on the Grados at anywhere from 7K to 10K with excellent results. I can't speak for the current lineup, but on the lower priced models I would not be surprised in the least to fi... | |
| how valid is a nagra recorder Absolutely. The Nagra stereo machines are excellent. | |
| Repairing older amps If you are looking at older amplifier, whether tube or solid state, after about 15 years or so you will want to consider replacing the filter capacitors in order to maintain the reliability and performance of the amplifier. Often filter caps will ... | |
| Speakers and Tube Amps Cleaneduphippy, you can also have the case where the impedance goes high and the tube amp will put out constant power. This is OK if the designer expects that. Impedance dips are usually not a problem too, as you have to sometimes shut down the ou... | |
| Help all ye Triplanar Gurus Sunnyboy1956, I've known Tri a very long time and this story did not sound right, so I gave him a call. Turns out their emai l has been down the last month or so and they are in the middle of changing ISPs (and apparently, doing a whole lot of con... | |
| Ortofon Per Windfeld Load Impedance? Zieman, the traditional problem with long interconnects is loss of high frequencies. I say traditional because the case of a low output moving coil is a special case. The source impedance of the cartridge is very low- often only a few ohms. Althou... | |
| which tube mono blocks? Darkmoebius, just for the record, I stated that about **all** amplifiers, tube *or* transistor!To restate: If your goal is sound quality, your investment in your amplifier will be best served by a higher impedance speaker (8 or preferably 16 ohm),... | |
| Ortofon Per Windfeld Load Impedance? First, my apologies for this thread going OT...Zieman, perhaps a discussion of cables is appropriate here.Cables have what is known as 'characteristic impedance'. This value is an impedance such that when the cable is terminated with this impedanc... | |
| Speakers and Tube Amps Duke said it better than I can. FWIW Wilson has shown with Audio Research a good deal in the past and ARC has Wilson speakers in house. So despite the dips in impedance, Wilson's are 'tube friendly'.The Wilson Watt has long been an example of the ... | |
| Ortofon Per Windfeld Load Impedance? Zieman, since our preamp is balanced we tried exactly that, since the cartridge is a low impedance source. The result- no difference. Single-ended; hard to say what you might hear since single-ended cables tend to be more susceptible to coloration... | |
| Ortofon Per Windfeld Load Impedance? FWIW when you have a loading resistance of only 100 ohms, the capacitance of the cable can be neglected. To illustrate this point, even if your capacitance was as high as 0.001uf, the frequencies affected would be measured in MHz.There **might** b... | |
| SRA Isolation Platform under a Turntable An SRA base under your turntable will likely be an instantly audible improvement! | |
| Speakers and Tube Amps The idea that an amplifier has to double power as the impedance is halved is problematic. I say this because **in general** tubes sound better than transistors and tubes do not double their power. Instead, they will (or they will attempt) to put o... | |
| Ground Loop Issue 427 Hi Spencer, your DVM can measure Ohms. Just put it on the Ohms scale; the reading you are looking for between the RCA grounds and the chassis ground should be the same as connecting the probes of the meter together.Most SETs have less gain than am... |
