| Technics 1200G vs VPI Forever Model One I concur that the Eclipse system, which I believe is the name of the package that gives you a SOTA motor, the drive amplifier, and the Roadrunner that feeds back to it, plus the required Hall sensor to give the RR something to read, is likely to b... | |
| Koetsu cartridges. They must be something special. Jason, I just read the long piece on "pickups" in Wikipedia. Seems there are a few different types and they operate in a few different ways, any set of which could affect the recorded signal in one way or another. So I would guess it is about as... | |
| Hagerman Piccolo Zero: New transimpedance head amp I did it but not with a Piccolo. I did it with a BMC MCCI and my aural results are to be found near the top of this thread. (1) where the cartridge has a very low internal resistance, it does make significant current output and is very good for dr... | |
| Source of Fremer's "1 arc second" claim? I don't think MF has anything whatever to do with OMA or even the K3, in a business sense. Odds are he borrowed the K3 from OMA for an extended period of time, but I certainly do not claim to know that for a fact. He may actually own it. And I d... | |
| Koetsu cartridges. They must be something special. This just in: platinum is not magnetic. The platinum in cartridge magnets is probably an alloy of Pt and Co, somewhat akin to Alnico (aluminum/nickel/cobalt) where both Co and Ni are magnetic. | |
| Technics 1200G vs VPI Forever Model One At this point in a thread like this (a "which one to buy" thread), all the cards are on the table. No one is going to say anything totally new to the topic or too revelatory. What will happen is you will accumulate opinions on one table vs the ot... | |
| Source of Fremer's "1 arc second" claim? All my TT experience suggests that speed constancy, the ability to maintain a single speed despite stylus drag, belt slip, belt creep, motor inaccuracy, etc, is much more important than speed accuracy (meaning centering a varying speed around 33.3... | |
| Koetsu cartridges. They must be something special. Yo-yo, so you’ve compared two kinds of magnet set up identically in terms of geometry and field strength and whatever other parameters pertain and compared them on the same Strat ( important to use the same guitar both ways)? And listeners agree t... | |
| Technics 1200G vs VPI Forever Model One I don’t think you can go wrong either way, especially if you have no particular preference for one type of drive system vs the other (Direct Drive vs Belt Drive). They really are quite different in their advantages and disadvantages. But otherwise... | |
| Koetsu cartridges. They must be something special. But I refuse to believe a magnet has a "sound". The magnet has an effect determined by its properties as a magnet in combination with the properties of the coils and its mass (of the magnet). The coil does not know it is being affected by a platin... | |
| What AC motor does BASIS use in their older 2500-2800 series TT If it comes down to having to pay $2K for a new Basis motor, I would consider the Eclipse system from SOTA as an alternative. Total cost is less than $2K and you get speed control in the bargain. | |
| Do vacuum tube test values reflect sound quality? "A mess" meaning there would have to be at least one or two more tubes, preferably of high transconductance to use as CFs. But could you then delete one of the 12AX7s and end up with the same number of tubes? While I recognize the importance of t... | |
| Do vacuum tube test values reflect sound quality? In a well designed circuit, tubes will last quite a long time, certainly many years, sometimes more than a decade. One of the few good uses for a tube tester (and I specify a tester that measures transconductance in units rather than as “good” or ... | |
| Stereo mode in phone stage going out I tend to favor porchlight’s suggestion that the fault is in the selector switch, because OP says it doesn’t happen with other inputs. on the other hand, if the stereo/mono switch is only in the phono stage circuit, in that case it could be that s... | |
| Do vacuum tube test values reflect sound quality? For a cathode follower you WANT high transconductance. Tubes like the 12AX7, used by many companies as a cathode follower, are not a good choice. They do it because there are billions of 12AX7s in the world, and more are being made in Eastern Euro... |
