| A good Preamp for ST70 We've rebuilt and updated a lot of PAS-3s and PAS-2s over the years- given it a new line stage, better parts, power supply regulation, stepped volume control and the like.What's fun about that preamp is that if properly updated it can take on any ... | |
| OTL Tube Amp for Maggie 3.6? We've had a lot of people use our MA-1s on the 3.6 to good effect. In fact the moderator of MUG (Magnaplanar User's Group) emailed me a few years back saying that the MA-1 was the best amp for that speaker.However 4est makes a good point about pow... | |
| Woofer sucking in and out Vinyladdict, just for the record (if you will pardon the pun) I have a Westerx LP mastering system, and it does not do any mixing whatsoever of the channels at any frequency, and every attempt is made in the design of the cutter itself to enhance ... | |
| MC loading at 47K This has been covered in other threads. However, in a nutshell there is a simple reason that you see variable results. It has to do with how sensitive the phono section is to Radio Frequency Interference (RFI).Now its a fact that at almost any loa... | |
| perfect speakers for atmasphere amp and preamp Well if its any help, Israel had a set of MA-1 MkIIIs up until about a year ago. They work fine with any of his speakers. | |
| Woofer sucking in and out I got rid of woofer excursion by paying attention to the effective mass of the arm/cartridge system. Once that was set up right, I had the added benefit of flawless tracking, in fact a lot of LPs that I thought had some wear turned out to have non... | |
| A Copernican View of the Turntable System It seems that in a live performance one is very rarely (if ever) as acoustically aware of space between musicians or their three dimensionality. My suspicion is that hifi compensates for the visual stimuli that is provided in a live performance wi... | |

| Why do some model names use "MKII"? We have used this nomenclature. Our first lineup did not use the 'Mk I' tag; that got applied after the Mk IIs were introduced. So the Mk I lineup went for about 17 years.The Mk II was the most significant update that we had developed during that ... | |
| Calculating total capacitance Lacee, 200 ohms would be **way** too low! I would start with something much higher, perhaps 20,000 ohms. Certainly you should not experience a drop in volume! If that occurs, you need a higher value. Note that this only applies to moving magnet ca... | |
| Triplanar VII and Benz LP-S I can usually contact Tri-planar anytime, but I never use the email to do it! Call him on the phone, 612-623-0922. | |
| Tube amps and speaker matching Tubes are expensive power. With efficiencies less than 89 db or so, you start to need a lot of power to really make the speaker play, although there is a lot of variance due to rooms and taste. So the power rule of thumb thing is generally OK but ... | |
| Why Don't We See More High Current Electronics? Atmasphere, technically there is no such thing as no feedback in an electrical circuit and hence a zero feedback amplifier, can you quantify your statement ?Loop negative feedback is what I was referring to. I have no issues with degenerative feed... | |
| The sound of glasswear From looking at these links, neither seems to support the kind of scenario that involves a preamp. They both look like some sort of malfunction in the amplifier.Many SS amps use a protection relay or similar circuit to detect DC at the output of t... | |
| FURMAN, PS AUDIO, ISOTEK?? The Furman is a good unit as long as it is not overloaded. It is used a lot where AC voltage is variable, as it will try to keep the line voltage stable (it has a circuit for switching taps on its isolation transformer).It is most often used in st... |
