Mounting: By boring one hole and inserting three screws, all of whi~ch are positioned by means of a metal template and plastic mounting pillar. These proved to be accurate. No overhang adjustment or alignment protractor is provided, although the exact position of the cartridge in the headshell may be slightly altered via the cartridge-mounting plate.

Cartridge acceptance: An additional screw-in weight is provided in the counter-balance, and with this inserted the arm would balance for cartridge weights…

There seems to be some confusion in the audio industry as to just which tonearm pivot is which. Some writers identify the pivots according to whether their axis lies vertically or horizontally, others identify them according to the mode of arm motion that they are related to. For the record, we wish to state that we use the latter system. (After all, the axis of a unipivot needle is vertical, but the arm moves both vertically and horizontally about the pivot.) When we refer to the vertical pivots, we mean those pivots about which the arm moves vertically…

Description: S-shaped tonearm. Counterbalance system: Rear weight sets static balance; light spring and calibrated knob set tracking force. Bias compensation: calibrated adjustment varies offset angle of force spring. Plug-in headshell weight (without pickup): 12.5 grams. Counterbalance range: 31 grams (shell plus Ortofon SI5T pickup) to 7 grams. Damped cueing lift lever. Isolated-ground four-circuit output.
Dimensions: Overall length: 12". Nominal length: 8.875". Rear overhang: 3". Distance from turntable center: 8.4375". Base-to-stylus distance: ?", from…

The V15-III's specifications (unlike those for the earlier models) include a statement about cable capacitance, calling for "400 to 500 picofarads total capacitance per…

The pickup does have rather high electrical inductance, though, which means it is not going to match all preamps…

The amplification was either a Mark Levinson No.25/No.26 preamplifier combination or an Audio Research SP14 driving my 1986-vintage Krell KSA-50.

Speaker cable was 15' lengths of AudioQuest Clear Hyperlitz, doubled-up for biwiring, while interconnects were 1m lengths of AudioQuest LiveWire Lapis connecting CD player to preamp, and preamp to power amplifier (1m lengths of Magnan V—an excellent cable—also served). Six-foot lengths of Madrigal unbalanced HPC connected the No.25 to the No.26. Source components consisted of a Revox A77 to play my own and…

I use a mixture of nearfield, in-room, and quasi-anechoic FFT techniques to investigate possible objective factors that might explain the sound heard (footnote 1).

As the Amrita MiniMonitor features first-order crossover filters, which can be time-coherent in behavior, I investigated the speaker's response to a 25µs rectangular pulse (fig.1). Fig.2 shows the manner in which this pulse shape is modified by the Amrita when the measuring microphone is on the tweeter axis, plotted over a 5ms window. The drivers appear to be connected in phase, but the up/down…
