According to Grado:
The All New Grado GT220 True Wireless earbuds utilize an 8mm Dynamic Driver to deliver rich accurate bass, detailed midrange and clear precise treble, resulting in a user experience second to none. Grado wants you to hear the music as the recording engineer intended it, true and natural, nothing artificial.
The GT220 incorporates Bluetooth 5.0 as well as aptX, AAC and SBC codecs, making it possible to connect with a wide range of devices. When the…
THe speakers was substituted for the SL600s in my usual system of Krell KSA-50 power amplifier, Audio Research SP-10 preamp, CAL Tempest II and Meridian MCD Pro CD players, and Koetsu Red/SME V/Linn Sondek LP player mounted on a Torlyte stand. (At the end of the listening period, I substituted a 1987 Linn/Ittok combination fitted with the new composite armboard and the new Linn Troika cartridge, the whole sitting on a Sound Organization table.) Interconnect was Monster Interlink Reference A, and Monster M1 speaker cable was used for…
I measured the frequency response in the listening window—spatially averaged to minimize room standing-wave problems—using third-octave pink noise, and measured the near-field low-frequency response with a sinewave sweep to get an idea of the true bass extension. The in-room response showed a smooth characteristic with a slightly falling trend above 80Hz, broken only by a slight excess of energy in the 3–10kHz region. The nearfield –6dB point lay at 55Hz, but, as indicated by Martin Colloms in his article elsewhere in this issue, an optimally damped small sealed-…

The Model 6 is a rather large four-way system employing an 18" woofer with a ½"-thick cone of light, rigid foam plastic (See "Farewell to the Paper Cone," in Vol.1 No.1 of The Stereophile), an 8" paper-cone driver for the lower-middle range, and compression-type horn units for the upper ranges. Crossovers are at 250, 800 and 3500Hz (footnote 1). A five-position rotary switch provides treble adjustments in steps of about…

Harry Weisfeld began his career as an audio manufacturer with the HW-9, an isolation base for Denon's DP-80 direct-drive turntable. (You could say the introduction of a VPI direct-drive 'table completes a circle.) Next came the DB-5 "Magic Brick," a wood-encased block of laminated ferrous metal said to act as a "sink" for stray electromagnetic radiation. Audiophiles around the world bought these…
One more thing: This arm is the first in my experience with VPI where the armrest lock actually locks…
One of the best pickups we've heard to date, the Grado A was introduced with some fanfare in the fall of 1964 (footnote 1) and then, for no apparent reason, was withdrawn just one year later. It is probably still available, though, either used or, discounted, as new stock at some dealers.
This is (was?) the cleanest-tracking pickup we have tested to date, by a small but perceptible margin, and unlike most ellipticals, its high end is extremely smooth, with no audible rise at all. A slight, broad response dip centered around 5kHz gives it a somewhat…
