| Anyone in Vegas listen to the Gilmore speakers??? What Mark tells me is that there are dozens of colors to choose from. They way I understand it, the infamous ad that has been so effective and controversial is a photo of a prototype, hence the blue color. If you look at some of the photos that Al... | |
| Anyone in Vegas listen to the Gilmore speakers??? Sorry to disappoint you folks. First off, we were in the back room when that dude showed up and played the system at such a volume. However, For the record, temporary exposure to 115 db does not damage hearing unless your ears have some previous d... | |
| Anyone in Vegas listen to the Gilmore speakers??? -it took me a while to figure it out. Mark Gilmore had told me several times on the phone that the speakers need 50 hours of breakin to sound right, and this was proven at the show. When the speakers arrived, they had 10 hours on them. Shipping da... | |
| What makes different amps produce different sound? Some other variables that affect the sound of an amplifier:Humans are relatively insensitive to even-ordered harmonics and astonishingly large amounts are usually not objectionable. Even ordered harmonics tend to add 'bloom' or 'fatness' (in the b... | |
| Problems getting the best out of my Berning -Its an easy mistake to make and it would give you the results you have. Try reversing the phase of *one* speaker cable and leave the other alone. Don't pay any attention to the markings on the amp- its possible that it could have an internal phas... | |
| Transformer coupled / Capacitor coupled The Audio Note, EAR (E11??), the big Jadis and Atma-Sphere (P-2) preamps are the only high-end audio transformer-coupled units out there to my knowledge.Transformer-coupling is common in professional tube gear, particularly from the 50s and 60s. T... | |
| Best Tube to eliminate RFI Sorry for my slow response- been out of town.If you are having RF problems, the first thing to check (IMO) is whether or not grid stop resistors have been used in the design. If not, they should be installed before proceeding with any other soluti... | |
| Best Tube to eliminate RFI Often tube shields are used to reduce hum pickup, which can still be a problem in RF circuits. Other reasons to install them include reducing noise and other nonlinear effects (especially in areas of strong RF fields). They are also used to reduce... | |
| Best Tube to eliminate RFI Tubes don't pick up RFI, amps do. If the amp is properly laid out and using proper grid-stop resistors (similar resistors are found in all transistor gear) the amp will not pick up RFI. I heard of a problem recently where RF was being picked up by... | |
| What is the cause of Mosfet Mist or Veiling? Hi Rwwear, if you remember reading that mosfets are not linear either you remember wrong or the material you read was wrong. Mosfets tend to have greater linearity then most bipolar devices.The Gamut is a good example of what can be done with them. | |
| Tube amp troubleshooting question You have one of three problems, or a combination thereof.(assuming that the output tubes are properly biased)Either the filter caps are bad, or the value of them is too high, causing excessive current to exist in the rectifier tube, especially dur... | |
| Is a Tube Amp Capable of High Current? Yes, Ghostrider, the output impedance of course is a current limiting factor as more and more of the output voltage is dropped across the output section as opposed to the load as the load impedance is reduced. However in the case of the ARC this i... | |
| Is a Tube Amp Capable of High Current? The idea of a 'high current' amplifier is a bit mythological. If your speaker is a 6 ohm load (not particularly difficult for tubes, BTW), then it is easy to show, using Ohm's law, what is really happening.Let's say that you've settled on a tube a... | |
| Preamp Matching? -You can't retrieve lost information in the amp if the preamp lost it! | |
| Integrated Amp for Girlfriend? -As long as she can get by with only 15 watts/channel. You'll need easy to drive speakers but the amp is very nice sounding and the investment is minimal.The unit will accept high output phono cartidges so a turntable is possible. The line section... |
